My wife and I both prefer a form mattress and this fits that well. Very comfortable and sleeping better. Cooler too. Pricey but you get what you pay for.
After sleeping on a conventional pillow top mattress it only took three nights to adjust to the tempurpedic. I love the sinking in feeling when you get into bed. It really conforms to my body and doesn't transfer any movement from my spouse to wake me up. Best decision I have made...wish I would have bought this years ago.
Came from base model we used for past 15 years. No break in period it felt great from day one. Also got a power base and live them both. If I get half as long as original one I'm happy.
