It is comfortable! The tall back reclines has adjustable arm rests and adjustable height of chair. Doesn't seem to roll well on my linoleum floor but that it pretty minor. Overall a great chair for the money!
I've bought this chair for two different locations in the house. The mesh seat curves down in front more than most padded chairs relieving pressure on the upper thighs. I sit in this chair for hours a day and find it very comfortable.
I purchased this the end of March and have been using it for about 2 weeks. Feels pretty comfortable. Especially like that I can sit back in the chair and feel that my back is supported. There is a moveable lumbar support on the back of the chair also. So far I am satisfied with my purchase.
