Beds: We tried the sleep number bed for a month and had them take it back. I could not get comfortable at any number. To me it was like sleeping on an air mattress with a good pad on top. I had a friend who found a hotel that uses the Temper-pedic mattress and spent a night to try it out...worth the expense if you don't like it. I hear it gets very HOT and if you are heavy at all you get stuck and it is hard to roll over.
We purchased another side by side, didn't think the others offered enough room. Be sure to check out the reviews on brands that. My son bought an LG and then found out the ice maker was very little and slow.
