    • perfect chair and great for price
Color: Pink Style: Fixed Arm
Review Image by Logan Walker Logan Walker
i am a 5'6, 125 pound female and it is perfect! it was very easy to set up with basic numbered instructions, only took about 10 minutes. its incredibly sturdy and everything works as intended, hydraulics, recline, and it rolls so smoothly. the chair itself is silent which i appreciate, and also incredibly comfortable. its honestly quite large and i still have so much room on the sides. the reviews scared me and i thought it was too small or for children but its perfect for regular sized people. ... show more

Best find! Affordable price with great quality. Easy to assemble, very sturdy, and the cushion is comfortable. The backrest supports my lower back perfectly. Fits well with a 30-inch desk, and I’m 5 ft tall.

    • For those with kyphosis, please read!
so, i have kyphosis, and this chair is just. wow. ive never been so comfortable sitting for long periods. i knew office chairs were better than gaming chairs for those with spinal issues, but i couldnt have imagined how amazing this would be for my back, and for such a cheap price. the back support thing is super sturdy, and the cushion on the bottom is super tough, perfect for the weird positions i have to sit in to stay as comfy as possible. honestly, the size is a little less than i expected, BUT its not a bad thing. i live in a very small space, so the smaller the chair, the better. however, i'm not too certain larger people can be as comfortable as i am. also, in terms of building, even for a total stupid dumb idiot like me, it was comically easy to build. even though i did use the wrong screws at one point, thats just because at this point im functionally illiterate from years of reading children's writing and trying to comprehend it. its VERY easy to build, and only took me about an hour (which is obviously increased by the fact my back is terrible, so i do things slowly) the little height lever thing also functions perfectly, which was something i struggled with in other chairs. it has a very wide range of heights, so if youre a bit on the... short side, like me, you can raise it like 6 inches (again, absolutely insane.) and it doesnt start that short, either. all in all, i am very VERY pleased with this chair. seriously, i nearly cried from joy when i realized i could do work from home without sacrificing my comfort. ... show more

    • Decent quality, good value
Color: Black Fixed Arm Style: 1 Pack
This chair seems to be identical to other chairs on Amazon except that this was the cheapest option. Any worries that this was a low-quality knockoff were allayed by the actual product. It is sturdy, well-built, easy to put together and comfortable. I'm very happy with this purchase.

    • Average Chair.
Color: Red Fixed Arm Style: 1 Pack
Color is amazing, so far durable. few steps to build but it took a while to build. not every nail fit in perfectly. rolls fine. not that cushiony but over fair for the price you get.

    • Comfortable chair
Color: Black Fixed Arm Style: 1 Pack
This chair was relatively easy to put together, and it’s great quality. Since it’s ergonomic, the back support is good, the seat cushion is supportive, and the wheels roll very well. The size is great as well. It’s definitely not oversized, but average office chair size.
