BOUGHT THIS FOR A FRIEND AFTER I HAD PURCHASED ONE FOR MYSELF. SHE HAD TROUBLE SLEEPING AT NIGHT AND ACHES AND PAINS IN THE MORNING WHEN SHE WOKE UP SHE LIMPED ALL DAY. SINCE SHE RECEIVED THIS MATTRESS SHE HAS BEEN SLEEPING THRU THE NIGHT AND WAKING UP WITH OUT ANY PAIN AND IS NO LONGER LIMPING. EVEN HER LITTLE GRANDDAUGHTER SNEAKS IN TO THE BED AT NIGHT BECAUSE SHE LIKES IT BETTER THAN HER MATTRESS. I HIGHLY RECOMMEND THIS MATTRESS TO ANYONE THAT HAS TROUBLE SLEEPING BAD BACKS IR WAKES UP SORE AND TIRED EVERY MORNING.. HAVE MADE THIS MATTRESS TO ANOTHER FRIEND WITH THE SAME RESULTS ALL I CAN SAY IS IF YOU CANT AFFORD THE ORIGINAL TEMPURPEDIC BED, YOU CAN AFFORD THIS ONE ITS GREAT. I LOVE IT AND YOU CANT TAKE IT AWAY FROM ME..
