i have been mattress shopping for about 9 months now and am just totaly confused. i really liked the sleep number. i will most likely buy it, but before i drop the 5g's i want to be sure. and as i am posting this an infomercial for one called the octaspring. anyone used this prouct? i need to bite this bullet soon, i can't stand my sleep pattern. my back is so bad after sergury and my current mattress is not helping things. do you guy's sleep well? i sleep 1-2 hours at a time. and the last month i have only been sleeping 3-5 hours per night. i need to get this done.
