My wife and I decided to Purchase a Tempur-Pedic mattress due to my back and neck issues. I noticed a huge difference after one night. I awakened with minimal back and or joint pain. I felt like it molded to my body! I like a firm mattress that will help keep my vertebra properly aligned. Like the old saying " why didn't I purchase this Mattress years ago. The thing I most like about the mattress so far is when you roll or turn I didn't feel like I was rolling out of a hole. My wife stated she did not feel me moving... Yay!! Win-Win. I'll check back and give an additional review after a few months
