Comfortable and Affordable
Color: Black
I normally dislike chairs like this, but with the budget I had I had to go with something more affordable. It is perfect and love how the handles go up to make a little bit more flush with the desk giving me some more room. The cushion is amazing, lumbar support is perfect for me. Very stable and I sometimes almost catch myself reclining back and wanting to fall asleep. Quality sturdy materials make it easy to attach any additional neck accessories to the chair. 10/10 would recommend.

Comfortable and Stylish Office Chair
Color: Black
The NEO Chair Office Desk Chair Computer High Back is a great addition to my workspace. It was easy to assemble and feels sturdy once put together. The high back provides good support, especially during long hours at my desk. The cushioning is comfortable, and the chair rolls smoothly without any issues. Overall, it looks professional and offers solid comfort for the price.

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!

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.
