After suffering from lower back pain at night (for quite a few years and about 3 mattresses), this bed has completely solved the problem!This bed is so cozy, like a cloud.  It sleeps cool for me and my husband (this was his biggest concern).  Our pup loves it too!  I feel well rested in the morning, no more snooze for this girl!  Definitely will recommend the wave hybrid to friends and family!  With the 100 night trial, why not!?
