ErgoGenesis "BodyBilt" J752 ESD / Clean Room Task Chair

The now discontinued ErgoGenesis "BodyBilt" J752 ESD / Clean Room Task Chair in Blue (ESD) Vinyl with the "Number 2 Deep Seat" and padded armrest option.This was NOT a low cost "mid-back" chair, so was it worth the money to purchase from this company (NO) ? See my "Hard Hitting" (updated) full report below . Above picture was taken as brand new out of the box in November 2010. It became rubbish exactly 10 years later (November 2020), but was in failure mode years before.

New “Radio Room” Chair / “Now For Something Completely Different”

Was in the hunt for a new chair for the "radio room" and wanted to TRY something different over the usual Chinese offerings that one sees in retail stores and on line. This of course entails most of what is sold today.

After some research the
USA Texas made “BodyBilt” chairs appeared to be very different (and desirable at the time to my eyes) over just about any chair on the market. They have been manufacturing office chairs since 1989~1990. What intrigued me first about these chairs was the offering of the very contoured seats (boy was that a mistake).

However , there is one other USA manufacture that is very near the “BodyBilt” offerings.
Also made in Texas USA is “Neutral Posture”. After a bit of research, there was in fact was a major legal battle in July 2002 between these 2 companies. “BodyBilt” won this particular court case.

Also has been at least one financial difficultly (bankruptcy) with “BodyBilt” over the years. The core company was renamed “ErgoGenesis” later on (was previously
“ChairWorks”, but this name is now used by a Taiwanese chair company).

“Neutral Posture” also markets chairs with different contoured seats. I also found the street pricing to be less too. But they just do not look as exciting for some reason?

Yes, what I found out in reality was very sour with this BodyBilt chair, as you will read below. As usual I’m NOT going to give any “rosy-candy covered” advertising type report. In the usual “Hard Hitting” N9EWO style. Mind you there are many other models and configurations of BodyBilt chairs (but we will only cover the one in review here).

Even if this chair I review here has been discontinued now, this should inform
YOU if it's worth dealing with this company and it's current products. The current mid-back BodyBilt "Task Chair" that still offers ESD / CR at the time this report was typed is the model J757.

Taking the Plunge / Arrived Almost Totally Damaged

Anyway, after liquidating a few radio goodies in order to finance this high-end chair, I decided to go with a “BodyBilt” ESD type J752 task model in Blue ESD vinyl. Mind you this is not your typical “Office Max” or “Staples” chair as the price is on the commercial side of the fence (ouch !). So it was major sticker shock. It was hand made to order and took about 4 weeks for it to be built (not including the shipping time) via Texas in the USA.

In my case it was shipped via truck (Estes Trucking). For what chair I ordered it was too big for UPS or Fed EX Ground. It came fully assembled (could the shipping method vary with the model ordered ?). The downside was the box arrived in very very bad condition (see photo below). Was heavily damaged on the lower end including being somewhat wet, but (whew) the damage missed the chair by inches. In my view the packing and thin box used were on the wimpy side for such a heavy high end product being shipped via truck. The chair was wrapped in plastic (as it should have been) ,so no water damage either.

The shipping weight was 73 lbs. The general chair (as ordered) was on the heavy side with its metal-chromed base it came with. Being a ESD chair that was a standard option.

Chair was sent via truck and the very poor shipping carton that almost did not make the trip !! As I read around the internet (including reviews on Amazon) , I'm not the only person to experience this with BodyBilt chairs along with very poor customer service. (N9EWO Photo)

Why a “BodyBilt” Chair / Ordering / General Model Features / Generally Modular Construction

Why a “BodyBilt” chair : At first I liked the selection of the heavily contoured seats (I did not know any better before this) and the most chair adjustments that anyone can have.

One needs to take the time and read and understand the options BEFORE ordering. It’s intense, very confusing (ergogenesis very poor web site not helping the cause), and even the representative in Chicago I talked to did not even know AT ALL what was REALLY up with this ESD model for options (duh ??). That was a song and dance exercise and I think I knew more than he did. He was more worried about his credit with any sale (I said "see ya later gator"….I was done dealing with him at that point). Customer service first strike !!

I ordered an ESD Mid-Back Task type (J752, now a discontinued model), with a # 2 type “Deep Seat” and upholstered armrests. See the chart on this page (below) for the exact details on what I actually ended up with.

NOTE: Additional “memory” sport foam option was NOT available on an ESD chair model. I went with ESD Blue Vinyl. Black vinyl is the other color option as well as a (Gray ?) fabric version. Sorry, there is no real leather available on an ESD chair from BodyBilt. Leather would have driven up the already super expensive chair greatly anyway (like adding $ 700.00 + USD more?).

J Mech (chair mechanics) was also ONLY available with an ESD model. There are other chair mechanic types available for other models.

Neat part with these chairs is the modular design (for the most part). If you need a new seat, back or armrests, you can actually order these parts (however at extremely high prices) and should be easy for the consumer to install or change out (this may not be in all cases of course) ? However we don’t know what pricing would be involved either for parts like the entire replacement seat ? Will a replacement seat cost half the price of a new chair ? UPDATE : Cost of a new SEAT (at the time this update was added in 2011) is $ 250. USD , NOT including shipping and handling.

Getting Used To The “Deep Seat”....NOT !!! / Many Adjustments / So-So Chair Mechanics

There were different seat types available when I ordered this chair. I went with the # 2 “Deep Seat” for more support as more seat to body contact for less pressure. Well that’s what the manufactures hype said .

"The deeply contoured seat gives for passive weight distribution via surface contact. This also encourages proper-seated posture and cushions the high-pressure points that lead to discomfort on flat seat designs."

With this # 2 deep "tractor" seat configuration, it positions your legs out quite a bit so you are forced to sit near “spread eagle”. This takes a bit of getting used to (OK more like NOT !!!).

Now in my view if this highly contoured (maximum) # 2 deep seat really does help with total seat pressure could be greatly argued ? I feel "thigh" pressure in the process no matter how much I adjust it. Proper seat height is important too. If it’s too low the butt area suffers , too high any your thighs suffer even worse. These are basic chair adjustments of course. Also ones butt needs to be properly in the seat. It too forward is no good either (or too far back). Without a "seat slider" adjustment with this ESD model (it's not an option) along with the #2 seat, it sort of locks you into place anyway.

One has to keep in mind that it takes time to adjust any chair to your liking and comfort, do not expect to do this in just a few minutes. It took me a good week of playing around and is still fairly uncomfortable. .

The # 7 Moderate seat is probably going to be best for most folks ?? The manufacture actually recommends the # 7 seat for most of its customers.

But the real gremlin with the # 2 deep seat for me is with the LARGE pommel (bump in the middle) and is covered more below. One Internet dealer says that most women prefer the # 7 seat to the # 2 seat and I can sure understand that (would a # 2 be even more painful for women)?

With the chair as ordered, I can adjust the seat height, seat tilt and tension, backrest angle, backrest height, armrest height and angle (arm rest tilt not available with upholstered type). Seat slider option is not available with the ESD model, but a similar backrest depth option is , but however I did not order this.

Talk about being the extremely versatile in the adjustment apartment. However to be fair, if one looks around (like I did) one can find most of these types of adjustments with some Chinese chairs at about 1/3 of the cost.

The mechanism was imported from Canada and does not look that robust to me (Northfield Metal Products in Waterloo, Ontario). The welds that hold the arm brackets on , look fair to me (see photo). Its body is anodized steel and some parts of the adjustment levers just feel very flimsy to me. The chair tilt adjustment can make some nasty cracking noises like something busted into pieces if you don’t support the seat properly before you engage it. Also when in the locked mode, it giggles around just a bit. At this price point, this seems to be a weakest "metal" part of it ?

A little note in regards to the "seat tension" adjustment (tilt when in free floating mode) . I found that you should tilt the seat fully (lock off) forward BEFORE adjusting the seat tension. Otherwise the knob may not feel properly. This one is not covered in BodyBilt manuals, or any Internet information on their website .

The ErgoGenesis "BodyBilt" J752's underside "J Model" chair mechanics (this part was made in Canada) To my eyes only "so-so" construction , also one has to wonder how long the the 3 adjustments (levers) will hold up ? The added welds for the arm brackets look fair to me as well. You can see one of these small weak welds in center picture above if you look close enough. (N9EWO Photo)

Perhaps not a real issue here , but should a high end "ESD - Clean Room" chair have rusty parts out of the box new ?? The rusty area shown is on the top of the steel armrest brackets (both of them). At least the welds look good here. (N9EWO Photo)

Seat Issures / Backrest and Chair Height Adjustments / Not All Bad News

Yes, we have vinyl covering being used in this chair. Of course will not be as durable as leather (again this is not available on a ESD chair). It is on the light softer side too and how long it will hold up will be another very interesting part we will have to see (Update : It did not , see below ) ?


NUMBER ONE : However only after a week of careful use we have I would call excessive “ripple marks" on the seat. You always have marks that are going to appear in the vinyl (or the foam) from pressure from your clothing. These should disappear for the most part in a few minutes after your butt is out of it ?? This could be a normal trait for a vinyl chair with a # 2"deep seat", but how much worse this will get is a good question (see photo below) ? UPDATE : In 2 years of use the seats glue that holds the vinyl to the cushion (yes glue) has totally lifted up. So the vinyl just sits floating in the air now. Also the vinyl has serious wear creases (see picture below) and I'm now just waiting for a major tear to happen . It has NOT held up well !!

NUMBER TWO (and is the MAJOR NASTY seat issue for me) : Next seat nasty involves a sharp feeling after you settle "sink" into it (say an hour or so). Involves the rear end of the seated area and feels like I'm hitting one layer (end of) of foam in the cushion that has either moved around or is just defective ?? Like a foreign sharp object is moving around in there. After awhile this gets to such a "sharp feeling" where I MUST stand up and get out of it.

UPDATE : After a number of contacts with the "so-called" customer service and only getting a royal run-a-round on this matter , I then sent a long email to the CEO of the company , then (and only then) did I receive a replacement seat. This was indeed a defective seat issue here, but is still uncomfortable anyway you try it . Anyway customer service was near a total joke for me (why did I have to go through the CEO to get action) !! Yes as covered above the seat has NOT held up well at all either in only 2 years after !

NUMBER THREE : (however this one is not a defect per-say and a much lesser issue, but for the record) Last seat bug for me is with the very large “Pommel” and may very well add to the uncomfortable situation. This is the bump in the middle that helps spread out the weight distribution (see main photo at top of this review). The # 2 seat places very undesirable pressure in the prostate area for me and of course gives PAIN (this would have to be even worse for a woman ??). Again one of course one must sit properly in the chair (back far enough and not too forward either) and have done this. But even with that properly executed, it can be a painful part of this chair for me.

There was a reduced “Pommel Foam” option for this chair that takes off 1inch of that area. Cannot say one way of the other if this would help the issue (untested) ? But I think if there is even less Pommel rise, could this make for an even a worst case issue in my case ??

It's not all bad news mind you. The backrest is super neat (but is not 100 % either, see photo below). The height adjustment has clicks and can be moved right where you need it. It can make a creaking sound while your back hits it, which is a bit annoying. Backrest angle adjustment also works very well.

The chair “gas” height adjustment works well too. Some chairs that have a gas cartridge for chair height have what I call “sink factor” as one sits down. This BodyBilt chair "gas" lift seems to sink down a bit more than usual (like its in 2 steps too ??). But is not a drawback to me at least at the time this report was typed .

Vinyl seat photo only 2 weeks old (left photo) , photo above taken "cold" at the start of a day. This vinyl has gotten much worst in only 2 years of use (right photo). Also the spray glue (yes glue) that sticks the vinyl to the seat cushion has now totally broken down , so the vinyl just floats now (sags bad as shown) in the air until I sit in it. There are other issues with this # 2 "Deep Seat" too (see text) , it's just plain uncomfortable after awhile (say under 1 hour). But the seat just does not hold up under normal use.
(N9EWO Photo)

In my view at this price point , construction quality (and some parts) of this "Body Bilt" chair severely lacks.You can see that the backrest does not "center" properly to the back of the seat. I can see no way for the customer to correct this nasty ill.  There is simply no excuse for this !! (NOTE : This picture above was taken when brand new, first day) Note : Adjusting the seat "mounting" (ever so slightly) with it's four mounting bolts made no difference with this backrest centering issue. None. (N9EWO Photo)

So Is It Worth It ?? / # 7 Type Seat Better ? / "Forget It" - We Say Stay Well Away from anything "BodyBilt"

Like I was saying at the beginning of this review that it was a very mixed bag for this J752 BodyBilt ESD task chair for me.

I find it to be "comfortable" only when one first sits in it. It does have an extreme degree of adjustments and the contoured seat which are the perks .

So with the TWO seat issues as covered above (#1 and #2, plus the Chair Back Also Falling Apart) and bad customer service issues , I simply DO NOT recommend BodyBilt chairs . Yes nice "vinyl" Chinese chairs actually DO exist even if these "high-end" high priced US chair manufactures say "no way" (of course they say that.....). Of course there are MANY junk Chinese chairs too ! See our reviews below.

I cannot say for sure if a # 7 Moderate seat would clear the Pommel issue up that happens with the # 2 type ? I have not tested a # 7 type seat and have no plans to do so at time this report was typed. The backrest being out of center with the seat is just another nasty that should not be at all at it's $ 1200. price point !

So the old saying: “You Get What You Pay For” is NOT valid here to me. Sorry that I must give a solid "thumbs down" for any BodyBilt chairs. WAY too much money for the low quality and the nasty issues I experienced (plus extremely POOR customer service).

As it goes with ALL office chairs sooner or later, the gas cartridge for chair height adjustment out went out just one month shy of being 10 years old. THAT part failure can be expected with ANY of them as they age.

I hope this review was of use and interest ? Caveat Emptor !

[It appears that this model / ESD configuration has been discontinued ?]

November / December 2020 (updated July 2023) :
We test TWO Chinese and ONE Taiwanese made Task Chairs 

After the BodyBilt disaster task chair reviewed above (and after it totally was not safe health wise sitting in it anymore), it was time to HUNT for a replacement for the Radio Room. Staying with the MID back type and not too expensive (no where near the overpriced BodyBilt junk chair as above). Of the THREE tested below, TWO were defective out of the box and were sent back. Were all UPS or Fed Ex "Ground" shippable.

We are not a fan of fabric upholstered chairs (too hard to keep clean). We also do NOT prefer ANY MESH type chairs and avoid them. So our desired covering is the Vinyl type (or better quality SMOOTH leather). Only one of the tests chairs had this. One with REAL (low grade) Leather and the last "el-cheapo " chair tested had very limited "Bonded Leather", most of this chair had very low grade vinyl. Nasty bonded leather is using a Vinyl (or polyurethane) base with vinyl and or PU covering that has Leather dust thrown in it. These usually wear out the fastest, the outer covering starts to PEEL away in time. However the plus side (and the only one) these are very soft but also usually lack seat support too as they usually skimp on PROPER amount of seat padding (or it gets compressed down in short order and or it's low quality that does not hold up in use).

Just like with radios, there is no perfect product here. As you look around are hundreds of office chairs being offered today, very overwhelming indeed and I have spend MANY hours just doing research ! So here we go below for trying to find at least something "reasonable" comfortable with no major defects of the 3 tested. IMPORTANT NOTE : For our BAD back and back comfort issues, I REQUIRE a chair that has seat and back as close to a 90 degree angle as possible. For many who like to lean back in a chair in normal mode my comments and reviews below may not be acceptable for YOU ! We say ANY chair that has seams on the actual seat surface (where you body makes contact with) shoud be avoided !

Global Industrial "Interion" 24/7 #T9F695506 (Black Vinyl - approx. $ 250.)

The Global Industrial T9F695505 is actually a decent chair for the money.
Also includes "seat tilt" which at this price point is quite rare.
Has adequate seat foam but it does have seams (but are not on top of the seat surface).
However the test sample arrived with a defective mechanism (see text below for update on this).

Country of Manufacture : China
Gas Height Adjustment : YES
Backrest Height Adjustment : YES
Backrest Angle Adjustment (independent of seat) : YES
Backrest Tension Adjustment : YES
Seat Tilt : YES
Seat Slider : NO

Upholstery Type : Ruff Finish Vinyl with Seams (Black)
Leg Base Material : Single Piece Plastic
Seat Base Material : Pressed Wood Chips
Carton Weight : Approx 40 lbs.

The Global Industrial #T9F695505 is a house brand and only sold by "Global Industrial" in the USA. The upholstery is made out of a alligator feeling ruff vinyl, so should be pretty durable (don't let the shinny pictures you see fool you if you desire a smooth type vinyl). Was overall was decent chair, except our test sample had defective mechanics. So it was returned and no second sample was attempted.

Seat even if only at a small 17 inches (front to back) has plenty of padding and being this is classified as a 24/7 chair is on the stiff side as new out of the box (but is also very supportive). Seat also contains side seams (but are not located on the top seat surface thank goodness), so cleaning might be more difficult ? But overall we felt it was very comfortable chair and at a great value (provided is received with no manufacture defects).

Typical wood seat base and the arms screw into the base as well with 3 screws each (width is also adjustable). Padded arms have height adjustment and are made of soft rubber like plastic, so should be most durable ?

NOTE : The Global web site photos above show the padded arms assembled backwards.

UPDATE : Chris B. sends a note that with most office chairs the backrest tension knob can ONLY be turned with the "seat tilt" FULLY adjusted FORWARD (of course IF a chair has that feature which this one does) ! However there was NO comment made in the skimpy single page assembly manual on this. Our test sample was promptly returned with it not working so I can't say one way or the other on this.

Honorable "Affordable" Mention (around $ 240. USD in July 2023) : The
Global Industrial "Interion" T9F506795 APPEARS to be another affordable decent model chair to consider if you can do without with seat and backrest rocking ? PLEASE NOTE : We have NOT tested this chair ! Is touted to have REAL Leather (NOW if it actually does is another story....I'm guessing it's of the Bonded type ?), 3 1/2 inch seat padding and LOOKS very comfy and also appears to have NO seams on the actual seat surface. Poly-shell (plastic) back and seat base (it's NOT using a wood base which is good thing). Arms attach to the bottom metal mechanics and not to a flimsy wooden base. Not totally clear if it has backrest amd chair base can rock (I do not believe so as we see NO tension knob ?), very hazy description on this. Price is slightly cheaper over the Global model above. It clearly does NOT have as many adjustments and that we can easily see this in the photos and description. The backrest angle is for sure adjustable (so hopefully does not have to be tilted back so much as shown below ?).

The Global Industrial "Interion" T9F506795 APPEARS to be another decent
model chair to consider if you can do without with seat and backrest rocking (maybe ?).
Does not use a wood base which is a good thing (most lower cost chairs use wooden bases)  !
Tilt of the backrest in the photos is disconcerting (can it be adjusted to a sharp L  / not tilted back so much ?) ?
Has seams around the rim of the seat , but appears not to have any on the ACTUAL seat surface (which is a good thing).
 (PLEASE NOTE : We have NOT tested this chair).

Honorable "HIgh Back" Mention (around $ 500 ~ 600. USD) : The Zuri "Draper" LOOKS to be a acceptable High Back shack chair in our research.  SOFT real leather seat (vinyl back), metal base (arm height is not adjustable). Available in various colors including the most attractive orange as shown below. More pricey than the two Chinese task type chairs above (but any high back style will be of course). Has the desired solid L type design. It's not one of those a fixed reclined types which KILLS the lower back !  (PLEASE NOTE : We have NOT tested this chair).

The Zuri "Draper" LOOKS to be a acceptable High Back shack chair in our research (not tested).
The orange color was the most desirabloe to our eyes (but is available in many other colors).

Eurotech 4x4LE - LM59802A (Black Leather - $ 500.)

The Eurotech 4x4LE - LM59802A in Black "Top Grain" Leather. Made in Taiwan (not China),
Generally decent, however the seam that runs across the middle of the seat was a deal beaker.
Was very difficult to sit in this chair for more than 2 minutes ! Also test sample arrived defective.
Rip in the seat and the Gas Height cartridge was sinking a good inch as new out of the box.

Country of Manufacture : Taiwan

Gas Height Adjustment : YES
Backrest Height Adjustment : YES
Backrest Angle Adjustment (independent of seat) : YES
Backrest Tension Adjustment : YES
Seat Tilt : YES
Seat Slider : NO
Upholstery Type : Ruff Finish Top Grain Leather with Seat Seam (Black)
Leg Base Material : Single Piece Plastic
Seat Base Material : Pressed Wood Chips
Carton Weight : Approx 60 lbs.

The Eurotech 4x4LE - LM59802A while very sturdy and heavy was just too uncomfortable to sit in. For some strange reason they put a nasty seam ACROSS the middle of the seat. With soft vinyl you might be able to get away with it, but not in stiff leather ! Has more than enough seat padding and is very supportive (is quite stiff), but it does not matter with that blasted seam ! Leather is a dull and ruff alligator style finish (don't let the manufacture photos fool you if you think it has smooth finish). Wood base as it usually is in this price bracket.

Alas it was defective anyway. Arrived with a nice rip in the seat and the Gas cartridge sunk a good inch when sat in. So this one went back as well ! So much for you would think better Taiwan made quality. Sorry it was not in our case.

N9EWO says "totally forget" this one !

Lemberi AB-EOC01 WM-08-01
(Black Bonded Leather - Discontinued. Was $ 85. + shipping Amazon only)
(was also sold under the "Bossin" Name / same model number, also Discontinued, Amazon as well / same price)

Lemberi / Bossin AB-EOC01 WM-08-1 in Black Bonded Leather, The lowest cost chair tested of the four.
Arms are attached to the backrest. Overall comfort is barely so-so.
Assembly can be a bit of a pain in the A$$ trying align the screw holes up (see text).
You do not want to tighten up any side screws until all are properly threaded in the holes.

Discontinued  / no longer available as this page was updated thank goodness.

But when you get down to it, this was another Chinese chair to take OFF the list anyway !

Country of Manufacture : China

Gas Height Adjustment : YES
Backrest Height Adjustment : NO
Backrest Angle Adjustment (independent of seat) : NO
Backrest Tension Adjustment : YES
Seat Tilt : NO
Seat Slider : NO
Upholstery Type : Very limited "Bonded Leather" with Seat Seams (Black),
(however most of the chair is using very low quality vinyl, see text)

Leg Base Material : Single Piece Plastic (Nylon?)
Seat Base Material : Pressed Wood Chips
Carton Weight : Approx 35 lbs.

The Lemberi / Bossin AB-EOC01 WM-08-1 in Black Bonded Leather (very limited) was the only sub $ 100. chair in our testing. We could ONLY find it available on Amazon under these two band names (same chair and model number). The card enclosed with the single page instructions sheet indicated the manufacture and or distributor as "Weave Gaming" (whatever that is ?). It meets our required 90 degree angle requirement (barely) and it's photos LOOKED decent enough. Yes, not all are going to happy with the sharp L configuration (and that is NOT adjustable).

Typical plywood seat base with arms that attach to the backrest with 8 total screws. Assembly can be a bit daunting as the holes do not line up 100% properly with the threaded parts in the wood (see our assembly tips below). So one needs to be very careful NOT to strip any of these screws. Be sure to assemble all loose and then tightening all up (equally) once all has been well started.

ASSEMBLY TIPS : Loosely insert the 4 screws to the "BACK" FIRST (these are more misaligned). Then CAREFULLY tip the entire chair on it's side (with the arms loosely attached to the back....being very careful !) and place the back and line up the seat bolt openings on the arms. THEN install the four lower bolts of the arm to the chair seat (again all loosely at first). WARNING : The LAST bolt you deal with will be the hardest to get threaded. TAKE YOUR TIME AND DON'T BE IN  HURRY ! Chair is light enough so setting the chair back upright after is not a big deal.

Leg base is of a single piece of plastic (nylon ?) which is good. So many lower cost Chinese chairs these days have gone to a 6 piece assembly base affair that uses screws. This is not very sturdy in our view. As long as the plastic is of adequate thickness and quality, a single piece of plastic is the better way to do it (sadly not all are after research on the internet with larger heavier chairs).

Tall padding on the armrests are extremely thin / weak material and appear they will fall apart in short order but that remains to be seen (UPDATE : in use they have  flattened and dimpled) ? There is a excessive amount of of lumbar support (after awhile is extremely annoying). It's gas lift cartridge was excellent with no dips or other nasties when sat in but this quickly started to go defective in only a month of use. Comfort level is just barely OK as between the excessive lumbar and seams in the seat is not so great (but no where near as bad as the EuroTech
LM59802A chair above). Would be a good candidate to add one of those lower cost "gel seat" add ons ?

The Bonded Leather has a very dull non shinny look and feel (once again don't let the ad pictures fool you). Downside is it was only used on a very limited part of the seat and backrest , otherwise this "cheapie" chair mostly uses about the lowest grade vinyl we have ever seen ! Also the vinyl parts in the seat became extremely HARD in less than a year of use and will most likely crack next.

But overall it was another one to forget about and clearly shows why to spend a bit more with a carefully chosen office chair !

WARNING (Updated) : From reading Amazon customer feedback this seller has a bad habit of taking an excessive time frame to send product or in some situations never receive it AT ALL (ditto under the Bossin Name again via customer feedback comments). Caveat Emptor (buyer beware) ! Best to forget this one all together. Also we need to add that the gas lift cartidge started to fail only 30 days after use (and then failed all together) with the test chair.

UPDATE (July 2023) : This chair is now discontinued which is not a bad thing. Spend a bit more and perhaps TRY one of the Chinese "Global" models listed above (my view here of course). We see variants all over the place of this Lemberi / Bossin chair in November 2022. Look very similar and most likely have the same issues.

.......and the Winner is ?

The $ 250. Global Industrial #T9F695505 24/7 chair is the winner here, provided no quality issues are experienced with the mech that we had new out of the box with the test sample (and was returned). Still available as of April 2023. We would like to test another sample on this model in time (donation ?). The Global Industrial "Interion" T9F506795  might be quite decent too as it does NOT use a wood chip base and is SUPPOSED to be leather (not tested).

Just plain FORGET the Eurotech 4x4LE - LM59802A. It is a real "pain in the butt" ! It's price has also skyrocketed way beyond what it's worth with in our view for very low grade real leather and a painful seat seam !

We ended up using the low cost Lemberi / Bossin  AB-EOC01 for now (until it gets heaved in the trash). But is near the bottom of the heap I'm afraid as it gets very painful to sit in after awhile ! Also don't expect a long life either (UPDATE : After only 1 year old year old it's about ready for the trash can, gas lift cartridge has gone bad and also the low end vinyl has become hard as a rock as well) ? But this can be said with ALL approx. $ 100. chairs. Again comfort is not good, it's seat seams and excessive lumbar "bump" being major nasties ! (UPDATE : Thankfully this chair has been discontinued and is no longer available. However as a WARNING , variants / similar style are still sold by others as it usually goes with Chinese products.

(USA made) Cramer chairs we made comments to in the past.....

Much more expensive Cramer RPM Fusion series does offer these options with what they call "6 or 7 way" models. This allows the chair (seat and back together) to tilt forward and back and to rock when seat angle is unlocked. Also includes a tension control with these 2 Cramer models. Seat and backrest bases are made from STEEL metal ! HUGE downside here is this makes the chair awfully expensive around the $ 800. + area (6 or 7 way mechanics with the least costly arm option).

Chair / Backrest "rocking " (and backrest tension) are important features I put as a must have with any office chair (this may not matter to YOU ). The Global chair above has backrest tension adjustment feature for around $ 250. so be it a Chinese made model. Now how well it's vinyl holds up in time is another story (unknown as I only used the test sample for a few hours.).

The Cramer RPM (properly configured) is WAY outside most folks budget range (including mine). But are something to consider for those who can afford and demand an above average quality "radio room " chair and want it to have MUCH better longevity !
