The only complaint I have is the mattress sleeps warm. It heats up to body temperature so if you live in a warm client it's a hot bed. The Restonic is just as comfortable as the thempurpedic mattress but you can save about a third or more of your money by purchasing the restonic. We have had it for eight years and love it! we move a lot and it has held up very well through all the moved and kids jumping on the bed. My husband has back problems and we shopped every store in our area to find the right mattress for him that was also comfortable for me. It does not matter if you sleep on your side, back, or stomach it is a very comfortable bed. We loved the mattress so much we also bought pillows that are also the same make. It makes a world of difference. Now we have a hard time sleeping anywhere other than our own bed. Even while being pregnant I was comfortable sleeping in this bed.
