I HAVE CRONIC BACK PAIN FOR OVER 45 YEARS, AND MUST SLEEP IN A RECLINER, THAT IS UNTIL I START SLEEPING IN THE MOST COMFORTABLE BED EVER. THIS MATTRESS ALONG WITH MY NEW ADJUSTABLE BED IS THE BEST THING FOR ME AND MY WIFE. NO MORE PAIN AND TRYING TO FIND A POSITION EVERY FEW MINUTES JUST TO END UP BACK INTO MY OLD RECLINER.  I MUST SAY THIS IS TRULY A GOD SEND FOR US.
