My husband got this chair for me and it is PERFECT!!! I am a side sitter meaning that if the seat is too big I will sit on one side. It wears the chair down very quickly and becomes very uncomfortable, I have back and hip problems anyway. This chair is just the right size for my hips, forcing me to sit in the middle. I am also short so the fact that the back of the chair has no hump my head is not forced forward, causing neck problems. This chair has a soft firmness to it if that makes sense. It's firm enough to give me the support my back and hips need but it is also like sitting on a big pillow! Thank you Tim for my PERFECT chair!
