anyone own a certified tempurpedic mattress?
i’ve read other reviews here and people i know love it, but i would like to hear more reviews before spending a couple thousand dollars on one. Has anyone purchased the foundation for it or what do i lay the mattress on?

Yes I own one. Although it is very comfortable and has helped my back . . . it holds body heat very badly. If I could get my money back I think I would try a different type of adjustable bed, I think I could be as comfortable without being hot all the time. If you and your mate are snugglers, this is NOT the bed for you!
I LOVE my tempurpedic but with a mattress no matter what the reviews say, it’s going to be up to you and your personal preference. I never understood why people put so much stock in reviews for mattresses which is a very objective product.
You may look into the new Sealy True Form. In my opinion it’s A LOT better than the tempurpedic. It doesn’t have a brake in period and it also sleeps cooler b/c it has a material called outlast on it. Outlast is what space shuttles use to keep from burning up when it gets back into orbit.
Why go synthetic?
Check out http://www.EssentiaDirect.com. Much better quality for the price. Natural memory foam..glueless…super comfortable.
