I purchased this in hopes it would help me get up without pain since my Dr put me on non-weight bearing after a recent revision of hip surgery. I also have had the other hip replaced, knee replacement and back surgery. I wish I would have bought it before but I’m in love with it now. The heat is perfect and not to hot and it compliments the massage which you can adjust to to you liking. I usually don’t write reviews but if you have medical conditions this chair will make your life easier and safer. Take it from a RA disease warrior!
