The SeatCushion by Tempur-Pedic™
Product Review (submitted on January 30, 2012):
This cushion is too narrow for a normal work chair. It's would be great if it were wider and didn't shift around in my seat all day and also if it was a bit thinner. The thickness of it made me so high in my chair that my feet didn't touch the floor. And YES, my seat was as low as it would go - duh! I'm about 5'3 and weigh 125lbs and the cushion is small. I am sending it back, but I did go out and buy the Tempurpedic chair. My bulging discs are very happy today! I highly recommend going for the whole chair instead of the cushion.
