Don't buy a Tempur-pedic if you aren't the exact size of your sleep partner
We purchased a Deluxe Queen Tempur-pedic mattress from Slumberland (separate review there, stay as far from that store as you can). My husband is 6'5" and 250 lbs, I am short, 5'4" 150 lbs. We were told that you won't feel a thing from the sleep partner. Well, that is absolutely not true. I am forced to sleep on the edge of the bed, because otherwise I roll towards him. They won't tell you that the mattress sinks in all around, causing the whole side to cave in.
This might be an okay mattress for average sized people that are the same size, but if you are 2 completely different sized people, PLEASE do not buy any Tempurpedic mattress, you will get stuck with something you will be very very uncomfortable sleeping with-the biggest $3000 mistake I've ever made.
