Our beautyrest silver is only 5 yrs old and just started being uncomfortable to sleep on. We were waking up unrested with aches & pains and I recently have had a very sharp pain in my back so I ordered this. So glad I did bc my back pain has subsided and my husband & I are sleeping like babies. We feel refreshed when we wake up and its only been 3 nights. Guess its bc it contours to your body that makes it so comfortable to sleep on. Love it!
