Perfect for College Students!
Color: Grey
I first bought this chair back in August of 2023. I used it nearly everyday for several hours. The chair just broke recently- the metal frame bent on the bottom of the chair (probably due to long term sitting and leaning to one side). This a great chair for college students looking for a more affordable but comfortable chair. The wheels move nice and smooth, the arm rests move up and down, and the back mesh of the chair is supportive, comfortable and breathable. To me, the seat of the chair is slightly bigger than a normal desk chair. It reclined decently far back and had a wide range of height adjustments. I just reordered this chair because I love it so much! I recommend this for anyone looking for a affordable, but comfortable desk chair!

as great as any 400 $ chair for so much less
Color: Black
This chair is wonderful. Easy to assemble, great home office size, not to overwhelming, very soft seating , great back support, adjustable in height and back. This chair meets all the expectation of a great chair.

This is the chair! Stop looking! You found it!
Color: Grey
Seriously, it's just a great chair.
It's comfy, it works, it's well made and it's a fantastic price. I picked this up after trying a "criss cross" style chair that simply was NOT working for everyday, all day home office work. This chair is great and I love that the arms can go up, which turns it into a great art chair as well! The back support is solid, although it's not cushioned at all so you may find putting a little lumbar pillow will help (it hasn't bothered me but over time the elasticity of the mesh has worn a bit)
It was very easy to put together and I've been using it everyday, for 8-10 hours a day for several months now. For price you can't beat it. It's also wide enough of a seat I can sit cross crossed.

Cheap and pretty comfortable, but poor adjustment functions.
Color: Black
Chair is pretty comfortable, wheels are solid and it holds height well. Biggest issue is the lean lock, even when engaged the chair does not hold an upright position, so if you're like me and prefer sitting relatively straight, this chair does not offer much support when doing so. Not bad for the price, but I would generally look elsewhere unless you don't care much for adjustment.

Pretty nice. Good price for a good quality chair.
Color: Black
Nice overall. Decent back support, but not really much going on there. Very sturdy chair and is comfortable. The adjustments are just enough to make it good. I would buy it again. rolls great. Easy to put together. perfect adjustable height. It works for my son who is around 5', my wife who is 5' 3 and also me and I am 5' 10.
