I have a tempurpedic foam pad on my normal mattress and it is AWESOME!! 6 years of waking up with back pain every single stinking morning is GONE!!! It made a world of difference for me. I actually make it to work and start doing something before my back starts hurting on some days and most days I don't have any pain at all. I would pay one heck of a lot more for a new one to replace this one if I had to, it really has made a difference for me.
