Good Basic Chair with a Few Drawbacks
Color: Black
I bought this Amazon Basics office task chair for my boyfriend who works from home. Overall, it’s a decent, simple chair that gets the job done for everyday use, especially if you just need something functional and affordable.
However, there are a couple of downsides. The recline doesn’t go back as much as he would like, so it’s not ideal if you prefer to lean back and relax between tasks. Also, after about a month of use, the wheels don’t glide as smoothly as they did at first, which can be a bit frustrating when rolling across the floor.
Overall, it’s a solid basic chair for light use, but if you want something with a deeper recline or super smooth mobility long-term, you might want to consider other options. Still a reasonable purchase depending on your needs.

Had for just over 9 years now and still pretty solid
Color: Black
I ordered this chair back in December 2015 for our front office, and it's been moved to our back shop where we fabricate. We're not a gentle work space by any stretch of the imagination; we build stuff and it's messy, lots of tools etc. This chair has held up surprisingly well!
The faux leather is delaminating almost entirely on the seat but honestly, I'd expect that for faux leather on something that is used daily. The seat pad, in my opinion, has gotten de-poofed. So it's not plush anymore but still usable. I've asked the guy that's using it if they want an upgrade/update and they said they like it and don't want to change it out just yet. That's saying something!
The size is nice and wide. We've had a range of differently sized folks sit in the chair over the years and the seat was always comfortable (less now without so much seat poof), I was able to sit cross-legged and the whole chair felt sturdy then as it does now. All of the standards functions you'd want an office chair to do, it can still do: it goes up and down smoothly, it rolls just fine, it's still pivot-reclines comfortably and doesn't feel like it's going to topple. I like it!

Good enough
Color: Black
Comfortable chair. Easy to put together. Allen nuts aren't cut perfectly so sometimes hard to get the wrench in there. My biggest complaint, and I didn't even realize this until I sat down in it, the arm rests are not adjustable and they are a little short for my liking.

COMFY CHAIR GOOD SUPPORT
Color: Dark Brown
So I needed an office chair because the one that I had wasn't really helping my back any. And it just didn't have enough cushion on the chair because when you want to sit for hours at your desk you want to be comfortable. So I took a chance on buying this chair. I thought the color was good and the price was right but I was still a little nervous because it said put together. So I got it right away only took 3 days. And the directions for pretty easy there were a couple of spots that I think we're out of order because you had to kind of play around with the screws going into the holes from the arms but I think if I were to get another chair like this I would probably do it my way because it's pretty self-explanatory but I followed the directions that came with the chair. And hey I'm 65 years old and I put this chair together. It's nice it's sleek and oh my God is it comfortable!!! Right where my lower back and sciatic is I get the support and it just feels good and I know that if I have to be at my desk for 3 or 4 hours I'm going to be comfortable. I highly highly recommend getting this chair.
The only issue that I had was the driver did not leave it on my porch. I had ordered a Vizio TV a couple months ago and the driver brought it up to my porch. So I just had to go out and take two steps bring it into the house I really appreciated that.
This driver didn't even come through the gate and there is no signs of any dogs because there aren't any. So this driver just left this giant heavy box it was about 35 lb in front of the garage where it was very visible from the road. And I had a dragon to my front door it was heavy I did not like that at all. But it wasn't damaged or anything and I do love the chair. I just don't like what the driver did.
