It's time for anew mattress, our current one is way worn out. I've tried the sleep number and didn't like them at all. I tried a couple from Sleep's which claimed to have been designed by an MD sleep expert (whatever!).
What mattresses do you like? Did you buy from a national store/brand? Did you take advantage of the alleged satisfaction guarantee? (Sleepy's charges a mere $175 for an exchange plus any price difference!)
