I love my tempur-pedic mattress/pillow...and my latest great find, my tempur-pedic seat cushion. I was unable to sit comfortably for more than 30 minutes. I found sitting at my desk at work and driving to be the most challenging. Any pressure to the backs of my thighs leads to pain in my lower legs /feet. This seat cushion has provided me with such relief, that I bought a second one so that I could leave it at my office.
