We've had our tempurpedic for probably 8 years now. Very good mattress, but the new ones are better. Definately look around - even the newer tempurpedic is better than our old one.
Still - it is a great mattress and has held up very well. The only things I have against it is that it is ridiculously hot in the summer and a has no "bounce." A little bounce in a mattress is kind of a good thing.
