The back rest does not provide support, however it would make a good lounge chair for sitting back. Not recommended for any desk work.

Similar to other reviews, sitting in the model in store had me sold on this chair. However once assembled at home it never felt the same as the one in store. The angle of the back puts you in a very uncomfortable position and makes my back hurt after 10+ minutes of sitting.
Not only this but the seat fabric has torn across the base in only 2 months of ownership and after "wearing in" the seat, both the base and back feel hard as a rock, the foam seems to have disappeared.
If you are considering this chair I would recommend buying literally anything else, even a bar stool would give you better posture.

This chair as the display model is super comfortable one of the best chairs I've sat in, but somehow that magically changed when I purchased it as a box, it does almost nothing for lumber support and little for comfort, the spine dip that's supposed to comfort your back makes it ache because it's at an 80° angle when it should be at a 90° angle, I wouldn't recommend this chair to anyone unless I want them to suffer.

I bought this thinking it'd be worth the money since it looks comfortable (my local store didn't have any in store, so I couldn't test before purchase. Assembly was tough as there is very little wiggle room to fit the screws in for the arm rests.

The seat is not comfortable at all. It looks like it has plenty of cushioning, but it seems to be a cheap synthetic material like dacron, so as soon as you sit down it feels hard and loses any support. It also has no lumbar support

I do not recommend this chair!

Very comfortable and incredible value for the price.

Perfect for my video editing duties.

This chair turned out to be very comfortable. Assembly was easy if you follow the instructions properly. I was going to buy a Racer chair but this was on special and feels more comfortable to sit on and game as well. Recommend it.

Comfortable chair, Purchased around 3 months ago.
No problems. It was cheaper then.

Comfy chair and easy assemble

Comfy seat with good texture
