Life changing!
I have had desk jobs my entire adult life and struggled with back/hip/leg pain from sitting for long periods.  I've tried everything imaginable...then I bought the Purple Cushion and I can honestly say I am 99.9% free of pain!  It only took 2-3 days to feel better.  I like it so much, I bought another for my home and am considering the mattress topper.
