in the last 5 years, i've owned 3 new beds. luckily all were returned w/o my having to pay more than once. my greatest problem (beside being a side sleeper) has been they're so "hard", they cause me to lose feeling in and/or use of one or both hands, esp. thumbs. tried gel; it feels wonderous at first touch. problem is, overnight the gel moves away fr your body leaving another rock hard mattress and pain. bought a fantastic topper that was double the price of others. such a pleasure; all pain gone. problem: the 10 yr. warranty is worthless. instead of dying in 9 mos. it died in about 14-16 mos. seller double talk; no exchange, no refund. i refused to buy again fr these cheats. initially, this mattress was to go in the guest room, but the reviews convinced me to try it on my boxsping. whew! overall the reviews seemed to indicate that it will last at least 2-3 yrs. for under $*. that's at least a thousand less than my beds w springs and gel. some said it felt too hard, but it felt like heaven to me. i slept all night. my fingers are crossed, but not in pain. my fingers are also crossed that it doesn't let me down like the foam bed my god-daughter bought for $800. this one was delivered fast and my movers got a kick out of my smashed bed in a zip lock bag. they stopped laughing when it puffed up a few minutes later. i can't say what'll happen later, but if this mattress fails me in the near future, i'll be back. right now, i'm satisfied.
