Interesting thread. My Dh and I have had the TP pillows for about 10 yrs. now. I think they are getting too old and we need new ones. Got it when I sprained my thoracic, lumbar, and sacaral regions. Seemed to help my neck greatly.
We have thought about a mattress, but cannot afford it.
I like teh idea of the sleep number mattress. One of these days we will get rid of our way too old mattress. Thanks for all the feedback.
