I bought a TempurPedic back when they only had one type... it was almost 20 years ago, and still is in wonderful shape, with no indentations or problems, so you definitely get what you pay for.
I used to have shoulder and hip pain ever morning, and from about 2 days after I got this mattress, the pain has been gone ever since.
If this mattress ever starts having problems, I'll definitely be getting another Tempur-Pedic, but I'll have to research them, cause I have no idea how mine would compare the new options out there now, in terms of firmness, etc.
