This chair is amazing. Most of my back pain is gone now and as a full-time writer I spend a lot of time at my desk. Great price too (it was on sale). Highly recommend.
I really do like this chair. I sit all day long and am comfortable. The only problem was assembly. It was tough getting the wheels on. Otherwise it would be 5 stars.
I especially like all the ways the chair can be adjusted. The neck rest is key for those long days at the computer. I also felt that my lower back was well supported. Would buy again.
