I've never really given it much thought about the quality of good rest and sleep until I recently started having back issues over the last 2yrs that I've been very restless and tossing and turning never getting a good night's rest waking up tired and sore. After constantly visiting the chiropractor twice a week over a year just didn't make a difference. So my last option was to break down and buy a quality matress and when I say quality I mean it, this is the last mattress I'll ever own. The best sleep I've experienced in years, I felt so rested and couldn't believe the pain relief from this mattress. Unbelievable!!! You definitely get what you pay for. Best investment I've made in a long time. I highly recommend.
