This vibration chair pad gives you a lot of options for comfort. It comes pre-programed with 4 set combinations or you can choose the area you want to vibrate on your own. For myself I choose the hip and thigh areas for my needs. It also has a lumbar area for heat therapy if you choose. Not noisy at all and it will automatically shut off after 30 min if you happen to get up and forget about it. Also gives me great support even if I choose not to turn it on. Extremely easy- use remote that stores right on the pad so you won’t loose it. Oh, and it has an adjustable strap for the back of the chair so it won’t fall over onto itself ! ..More
