We bought this mattress after testing it out in stores and thought it would be our forever mattress since we're hot sleepers and everyone always recommended Tempur-pedics. What we didn't know is that this mattress is only cool to the touch, meaning when you first get in bed it's cool but your body heat will warm up the bed. There's nowhere for the heat to go, so after 15 min the 'cooling' feature is gone and you're stuck sleeping in a warm/hot bed. The only option is to move to another part of the bed to get the cool feel again but you're basically moving around all night or sleeping in a hot bed. Unfortunately we got this bed as a 'all sales final' deal so we can't return it and are now stuck with a hot bed.
