This is definitely firm, at first you might go "I made a mistake, I should have gone medium". But it softens up pretty quickly to the right point. As someone with multiple herniated discs, this is so far the best mattress I've tried. No ache in the morning when I stand up, which was usually the problem with my old mattress. It's comfy, not terribly warm (compared to what people were telling me), and it has just enough give to relieve pressure points that other firm mattresses create.

Purchased same mattress a few years ago and I sleep really well on it. Seamless process from purchase to delivery

Love the Tempur-pedic material combined with traditional springs in the Hybrid model. Wish Tempur-pedic's website was better. Never bothered to ask if we also needed a foundation, so we had to put up with two deliveries when they showed up the first time with just the mattress ??

We had a temperpedic previously and it was great this one is awesome also. I cannot sleep on any other mattress pain free

This mattress is supportive and very comfortable. It does not sleep hot at all. It is my second one in 17 years. I have a genetic problem with my back and when I started experiencing pain I knew it was time for a new mattress. It has been a life saver.
