I don't fit real well into the chair. Seems that I'm listing to the right and need to put something under my bottom to make my back straighten out. Otherwise very comfy.
Assembly instructions were easy to follow but the seat and back should have been put together first. Before being put on the base due to chair rolling away from you while trying to get the back attached to the seat assembly.
I'm waiting for Lumbar surgery and this chair supports the injured area very well decreasing the pain by a huge amount. Very good chair at a reasonable price!
