Nice chair but definitely not breathable.
Color: Black
Once I figured out the arms had a left and right...the chair was easy to put together. The faux leather is nice. The seat is (or will be once I break it in) very comfortable. I have 2 minor complaints. It is extremely straight up and down. I haven't had much chance to play with it to see if I can get it to recline even an inch. That would help. And number two, it's HOT. I'm going to have to get some sort of seat pad because the pleather is not breathable and every time I get up my bum is sweaty. I know, TMI. But all in all I think it will serve my purposes.

Highly recommend
Color: Black
Beautiful chair, comfortable and rolls well, the directions were not very clear, we had the seat on backward at first, but finally figured it out and the chair is perfect, I've had it over a year and it works perfectly

Good quality, fairly easy assembly
Color: White
Comfortable chair as advertised. Assembly time about 20 minutes with one screwdriver needed.
(Note: don't follow the instructions included. Lay the left arm assembly down on the floor and THEN affix the seat, followed by turning that over on its side and adding the right arm assembly. Trying to affix the two arms in an upright position is too difficult as directed.)
The only thing I don't like about it is the fluted upholstery on the seat and back, where a bit more padding would have helped greatly. Otherwise, it's comfortable and functional and reasonably priced. Delivery was on time.
ADDITIONAL COMMENTS AFTER 18 MONTHS OF USE: I've used the chair for 6-8 hours a day. The leather on the arms is cracking in multiple places. This is a big disappointment. And speaking of the arms, there's a major problem with the sewing of the leather on the outside edge of both left and right arms: the stitching is on the top at the outer edge, which means that it forms a jagged edge that your arms scrape on when resting on the leather. That jagged edge scraping my skin has caused a great deal of chafing, is most irritating, and could have been avoided entirely if they had just applied the stitching one inch further down on the side rather than along the top flat edge. This is a major design flaw. I will not buy this chair again because of the one flaw and the too-thin, cracking leather on the flat top of the arms, which is too bad, because it's fine in all other ways.

Good, but not great
Color: White
I work from home, so having a really comfortable chair that supports my back and provides me a nice place to sit for 8 hours is really important to me. I ordered this chair in March 2023 and was really happy with it at first. Sleek, easy to put together, and comfortable. I then had an issue with it because after I sat on it while wearing leggings, the entire seat and armrests turned black from the fabric. No other furniture I own turns black from my leggings. I reached out to the seller and they were kind enough to provide me a replacement for the seat and the two armrests at no charge. I went through the whole summer and didn't wear leggings. However, I am now in Oct 2023 and wearing leggings again. The chair seat and armrests are black again, but there is also a lot of wear to the chair in general. I understand I sit in it a lot, but the seat lost its comfort factor. Additionally, I lean on the left armrest a lot and it shows - there is a large indent on it. The fake leather material is just not for me and the chair no longer looks attractive. I wish it lasted longer considering how much I paid for it.

Worth Every Penny
Color: Black
Bought this chair Aug 2023 and as i come up on 3 years with this chair i can say i absolutely love this chair.
i bought this chair when i was having very bad back pain and assuming my old chair was to small i decided to purchase it. Zero complaints about this chair at all, no rips, cuts or broken parts. The chair does have some cracking but that's because I'm fat so its a lot for the chair to hold on a daily bases. I give this chair a lot of props for removing my back pain considering my back pain was due to a popped gallbladder that was infected..
If you are reading reviews and looking for a good chair that's worth the money just get this. Its easy to assemble & it has great stability AND most importantly it holds the weight of myself.. I'm built like a butter ball turkey..
