I really am enjoying my new ReST bed. I sleep longer and deeper than I have in any other bed of my recollection.I just turned 87 so I have a lot of experience! The only drawback is that I hear the ‘whoosh’ and clink of the bladders inflating and deflating. I am comforted by the fact, however, that they are relieving any pressure points that I might have if they didn’t accommodate to my body and its various positions. Once I’m asleep, I no longer hear those noises.
