Scottiemon has a bad back, we slept on waterbeds for 25+ years. We have usually slept on $20-$25 inflatable mattress for the last 8 years of fulltiming except for the ten nights we tried a Select Comfort Sleep Number Bed. Made her back much worse, then had to jump through all kinds of hoops to get our money back. Back to the $20-$25 air mattresses, they last about a year and we get another one. We've tried the Aerobeds with the built in pumps but they don't last 4 months as a rule for many times more money.
