I have a temperpedic imitation from Cotsco. It is 12 inches thick. I got it after I broke a few bones and hurt my back badly from an accident and I love it! It was only $500.00 2 years ago.

I don't feel hot in my bed. I just run a fan on hot days in the summer. But that is just me. I tend to feel cold more than most people. I dislike being cold!

I like the idea of the wedge for draining sinus issues with allergies. I never heard of that before but it is worth a try!! I will have to see if my allergist will write me a prescription for that!!

Good luck with whatever you decide. I do like the idea of a mattress that raises up and down like the hospitals have.
