Nice chair, w/ good cust support
Color: Black, Style: Classic
I apologize for length, but if I am doing a review for other people I assume you want to have as
much info as possible to make a decision. I feel this chair is for tall/fat/both so will review it as
such. At 6’4” @ 350lbs I fit into both, but reviewing based upon my body, yours is different so
adjust according.
TLDR – Would buy again, cavernous comfy chair with excellent customer support. Only
personal dings against chair are the back could be taller, but added back due to support.
Parts + Fit/Finish + Assembly:
The parts have some heft and feel solid as expected for a chair designed for heavy people.
Material and stitching look proper and I see no flaws. My box was beat to hell and ripped
opened at one point. Packing material took the hit and did its job as the items were unaffected.
The gas cylinder for the chair was missing and assume lost during shipping. (see customer
service). Assembly was standard office chair fare with simple and clear instructions.
Wheels / Height / Controls:
I normally wouldn’t think of mentioning wheels, but it’s different than expected. They are
good, maybe too good. A slight kick to push you back on wood floors sends you flying. The
height adjustment for me is good/standard. At full height my feet are flat on the floor and
where I would have the chair even if it went higher. My wife (5’6”) at that height is about 2.5
inches above the floor. Taller people than myself may wish for more height. Chair controls are
standard fare and operate smoothly
Seat:
It’s large and with the arms is there is nothing even close to your hip/legs. I can put my fist on
my hips and my arms barely touch the chair arms. This is why you are thinking of this chair, and
for that you will not be disappointed. The seat is not pillow soft and IMHO a little firmer than I
liked at first, but after a few days got broken in or I adjusted. I am a programmer + gamer so
spend a lot of time in the chair for hours on end. Comfortable and no complaints at all. Seat
depth for me is ~1” from my knee and good with roughly 20.5” usable butt/thigh length. That
should be fine for big/tall but may be a bit much for big/short. Measure your current chair and
decide from there.
Back:
The back lets the chair down a bit for me, the big/tall user, as the target seems to be big/short
users. The back ends just below my shoulder-line. That obviously means no leaning my head
back and the headrest is squarely on my shoulder blades. Not uncomfortable, but I’d prefer a
taller back. For me personally I’d like it to be extended 4”, but that would likely be an issue for
shorter users. I feel if the manufacturer increased the back by 2 inches it would be an ideal
compromise for all users. The chair has an inflatable lumbar support, which I did not use as I
personally find those uncomfortable. Also note the chair is designed for a more proper posture
with a 90deg back and not a more relaxed 100-110deg. Neither pro/con as personal
preference.
Arms:
The design of the arms being supported by rear only as mentioned earlier allow for an
abundance of hip/thigh space. This is an excellent ergonomic design with a potential caveat.
More stress will be placed upon the connection/joint. The joint for this chair is just shy of 4” so
seems beefy but only time will tell if it holds up to the lateral force of leaning on it while
reading. My chairs tend to last 5-7 years, due to the right arm feeling wobbly or the chair
leaning to the right. The arm adjustments provide a nice front/back of ~3”, from touching chair
back to 3” gap between chair/armrest. The height is similar and also moves the armrest
forward about another 2”. At full forward/up the armrest are higher than I like so should easily
accommodate taller users.
Customer Service
My chair was missing a part that I suspect was lost during shipping due to box condition. I
contacted them Sun (7/20/2025 @ 1201). At 2228 that night I received a response that they
acknowledged the issue and gave a tracking order for the missing part. The part arrived Mon
7/28 and gave a few days to test it out for review Fri (8/1). Obviously you don’t want an issue,
but if an issue arises how a company handles it tells you a lot IMHO on how they feel about
their product. I am very pleased with their handling of the matter.

Great Chair
Color: Black, Style: Classic
The durability, recline, noise, fit, and appearance, and stability of the chair were all fantastic. As someone of a shorter height, the backrest which is normally way to high or short for my head fits perfectly. The chair itself is easy to assemble and very comfortable to sit in for long hours. I tend do a lot of work at home and this chair feels very comfortable without feeling the need to get up. The chair looks great set up in my office and is honestly a great office chair. For moving around a room, the wheel guides across my carpet very smoothly with struggling unlike my previous chair which would need a heavy push. Not only that, the chair is noiseless which is a plus for people who get bothered by little sounds when moving around. The fit could honestly fit anyone of any size as the chair itself is quite wide and roomy for me. The seat is also made up of faux leather and feels well stitched and quite durable.

Decent Price
Color: Black, Style: Classic
Chair arrived and was missing critical component so that I could not assemble it. Contacted seller and they sent me a similar component within 2 weeks. Chair was now easy to assemble and very comfortable to use for long periods. Although I wished it could raise another two inches. Also be aware chair might be challenging to get thru a standard 29-30inch doorway but not impossible. Thank You Seller for your help.

Easy installation and comfortable
Color: Black, Style: Classic, Color: Black, Style: Classic
This chair features a premium, quilt-stitched design with thick cushioning that immediately feels supportive. Installation is straightforward — the major components align cleanly, and the hardware fits without forcing, allowing the entire setup to be completed quickly. Once assembled, the chair provides excellent comfort: the padded headrest, wide seat, and soft armrests create a stable, ergonomic sitting experience suitable for long work sessions. The overall build feels solid, and the smooth-rolling casters add to the ease of use.

Seat angle problem
Color: Black, Style: Classic
This chair is very good. Has exactly the dimensions I was looking for. Overall it looks very well made, excellent quality, easy to install. I'm not giving it 5 starts because I'm not liking the angle of the seat very much. It goes low at the back end and at the front it is very high. It feels really good when I'm working on my computer where I have 1 widescreen monitor with 2 smaller ones on top, so it is very comfortable there. But not so much when I'm just working on my desk filling forms and reading papers. I'm actually getting low back pain. I wrote the seller to ask if there is any kind of adjustment I can make but it doesn't look to me like there is anything than can be done. I'm still keeping it.
