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.
I live in a remodeled garage where the floor is concrete. This chair supports my back and floats around the floor like a dream. It was super simple to assemble and is a recommend from me!
