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.

Great desk chair for kids/teens
Chair is super comfy. My daughter loves the style and has been in it months since purchasing. It’s held up in terms of quality.

Great value and quality
Bought this for my 19-yr old daughter to use at the desk in her room. The chair was a fantastic value, went together easily, and looks great in her room. I was honestly surprised at the quality! I think she will enjoy it for years to come.

Pretty pink chair
Definitely a good value for the price , really easy to put together, works well, and it’s comfortable! I was worried that it would be too small for me (218lbs) but it was just fine. It feels stable and durable and it’s adjustable in height.

It's okay
Chair is small. Comfy enough, nor super comfy. The back does not recline nor is it adjustable. Cute though. Pink is the exact pink in the pic .Will probably return.
