I have been experiencing back and neck pains for a while. I initially thought it was my pillow so I switched to about a dozen different types of pillow. Even tried the ones advertised on TV and infomercials. I finally decided maybe it was time to switch my mattress and one night on this posturepedic mattress my back and neck pains were gone and I have not experiences any pain since. Only a restful, painless nights sleep. I am about 6 foot tall and 200 lbs and this mattress supports me very well.
