Query: QUITE HAPPY!!!

i bought this for my boyfriend about a week ago...he frequently mentions he has back pain (diesel mechanic) he's used it probablly every night. it's king size so it's long and wide, covers more area..i've used it a few times as well. it's a very nice product. haven't tried the "moist" heat feature yet...just regular. it's soooo nice..sometimes it puts me to sleep!! i'm short 5'2 so when i lay on it, it gets my lower back AND my shoulders.
