Great product!
I have bursitis in my hip and this has help me be able to sit on the hard kitchen chair longer.  It took a few weeks for my hip to stop hurting, but now I can sit for an hour and not look like a 90 year old woman when I get up from the chair.  Very comfortable.  I'm small (5'1" and 108 lbs) and don't notice any problem under my theighs like some others talked about.
