My husband and I recently bought a Serta Perfect Sleeper Pillowtop Grandis.  We both had been sleeping with an extra pillow under our knees for back relief, without much relief! It would take me 30 minutes or longer to go to sleep due to pain.  Now we can lay down with support under our backs and knees as the memory foam conforms to the contours of our bodies!

 I do not ever want to be without my mattress.  We go on "short" vacations because we are uncomfortable sleeping and anxious to get back to our sweet comfortable mattress.

 I would highly recommend this product to anyone with Arthritis,...
