This is the 2nd tempurpedic bed we have purchased; the first being a Rhapsody. I was excited to get another after owning the glorified air mattress for a few years. Sadly this one does not meet up to what is needed. The longer we own the bed the worse I sleep (which means my husband sleeps poorly also). Additionally, it has been causing more back pain and I now have my arms and hands go numb. I toss and turn all night long too. No exaggeration. It's causing my mental health to take a dive again because I cannot get the restful sleep needed. In my 20's I had a few car accidents ranging in severity so the muscles in my back cause quite a bit of discomfort as well as a medical issue that causes muscle and joint pain. When we had the Rhapsody, it was great. A little too firm but worked well otherwise. Both my husband and I do not feel the cooling effects from this bed either. If anything, it's like it heats us up 8 degrees or more through the night.
