Very comfortable to work on a daily basis and super easy to assemble.
Color: Black
Size: 21.7 in D x 21.7 in W x 38.2 in H
It really surprised me for good. I have been using it for a while to work at home, and the mesh backing is a relief because it doesn't give any heat. It's quite comfortable, the cushion feels good and the back support helps a lot during long sitting days. Besides, putting it together was very easy, it took me almost no time. For the price, it's great, it does its job very well.

Great chair and great price.
Color: Black
Size: 21.6 in D x 21.6 in W x 38.3 in H
Super easy to put together. Got for my kiddo since he does school from home and over summer did some computer gaming and he really likes it. We both think it's comfy and functional. Perfect size to be able to be pushed and fit under the desk. Rolls and carpet smoothly. And the material is much better then the fake leather computer chairs that we keep going through. I will be getting another one of these if I ever get a work from home job.

Great chair for a fair price
Color: Black
Size: 21.7 in D x 21.7 in W x 38.2 in H
Wonderful chair easy to build just make sure your using the correct screws it tells you to! It’s sturdy and durable I can fully lay back without fear of it completely falling under me and with a sleek appearance and design I’d definitely recommend

Good, cheap, small.
Color: Black
Size: 21.7 in D x 21.7 in W x 38.2 in H
The quality is better than expected for the price. Seat cushion is firm but not overly hard, wheels roll nicely, piston goes up and down smoothly, and assembly is quick and easy. The one major caveat is that it's quite small. If the user is going to be maybe 5'4 or less, it'll work (this was for a child, so it turned out great). But even on a 5'6 user, the seat is rather shallow (front to back) and the armrests are so low that your elbows won't reach unless you have freakishly long arms. If you're after a cheap office chair for brief adult use, or for kids, this is perfect. I don't know how they turn a profit given that it's a fully functional office chair, shipped from China to your doorstep, for only $30. However, if you're of average height or bigger, it's probably going to be too small for you.

Comfortable but MUCH smaller than expected
Color: Black
Size: 21.6 in D x 21.6 in W x 38.3 in H
I’ve been using this chair for almost a month for work and studying. For the price point, the quality is pretty decent. It feels comfortable, adjusts in height, and mine hasn’t been super squeaky or wobbly. BUT bro, this chair is SMALL. That’s the biggest thing I would keep in mind before buying. If you’re taller or bigger, I really don’t think this would be comfortable. The seat feels pretty tight and seems much better suited for someone smaller and shorter. Assembly took me a while, but I eventually figured it out myself. Disassembling it though?? Especially the bottom portion… good luck. I had to take mine apart and that was way harder than I expected. I just really wish they made the chair a little wider. It’s comfortable for me, but the size seriously limits who I would recommend it to.

So comfortable
Color: Black
Size: 23.8 in D x 22.3 in W x 38.4 in H
I have POTS so sitting in one position for too long is very uncomfortable, but this helps wonderfully. Being able to move the arm rests back means I can criss cross my legs if I want to and nothing will dig into my skin. I also love having a chair that is “me size” since I am a bit on the smaller side, it takes up much less space that way. Comfortable for long term gaming, and it was easy to understand the instructions when putting together. the only thing I dislike is the mesh because it hurts when wearing shorts and there is skin contact and any pet hair will stick up out of it like a sharp nematode, but I cover it with a blanket and the problem is solved for me. This is my first chair that I’ve owned that hasn’t been secondhand so having no issues has been very nice. The price was also great when I bought it, at least $15 cheaper than the cheapest non mesh version
