For anyone who is interested, I wanted to give some (I think) valuable feedback on Tempurpedic products. I was a die-hard Tempurpedic fan, with the emphasis on "WAS"- we have had their mattress and pillows for several years now. My hubbie gave up on the pillow a long time ago because of softening, but truthfully I still find mine comfortable. The bed is a different story. Count on the bed lasting for about 4 years only! My husband and I are both thin, and his side started softening after 4 years. It is now 4 1/2 years later, and while my side is not as soft as his, it is catching up quickly, and we both wake up with backaches. The company is cute too- their warranty requires a .6 inch depression, but won't cover extreme softening so as to make the mattress no longer supportive. When you press it with your hand it even has a cellophany-type noise. The company has been non-responsive. If you really search online, a lot of people have had similar complaints. I think a mattress that costs in excess of $2000 for a king size should have a life span for more than 4 1/2 years. Avoid an expensive mistake...while it retains its firmness, it feels wonderful, but suffice it to say I am replacing it with another brand mattress. All of the memory foam suffers from similar limitations as far as I could ascertain talking to salespeople and from my research.:disgust::frown::|
