There is a sleep number bed store at the mall. One day after walking around the mall for an afternoon I decided to head in there and try one out. I ended up taking a little cat nap, when I woke up the salesman sold me a bed! I am not like those people on the commercials with a set number that I always sleep on. I find it nice to have the option to be able to switch up how firm or less firm I want my mattress.
