My wifeee has sleep problems too...even here at home and our mattresses in the guest room and our bedroom are upgrades from the originals we purchased and they still have only lasted a couple years under warranty
.May have to get them to upgrade again...they did not charge the difference in price the first time since the beds didn't seem to be as good as they had warrantied...if they won't do that again for another upgrade we may join those of you have oneand get a sleep number too...We haven't priced any yet are they reasonable for RV's?
