I take the right side. I used to take the center then my current and long time roommate moved in. I learned two words - Compromise & Voluntold. I was voluntold to move over to the right side
I got tired of my bad and really wanted a new one. The water bed is still the very best, but you have to tolerate the eventual leak. So I bought an air bed instead.
The first thing you learn about an air bed is that it won't go on a frame, so it sits on the floor, and the temperature of the bad is the temperature of the floor. Electric blanket under the mattress and you are sleeping in heaven.
The second thing you learn is that you can't get out of an air bed. It is too close to the floor. I poked through the family storage shed and found a bunky board. Since mattresses are now made with springs inside, they had to invent the bunky board to take the place of the box spring and raise the mattress to a height where normal people can get out of it. A double size bunky board happens to be exactly 3 1/2 inches smaller than a queen size mattress, so I bought some lumber and made a box to keep the mattress from sliding around. The third thing you learn is that an air mattress slides around if you don't tie it down somehow.
The fourth thing you learn is that nobody makes fitted sheets that fit an air bed. They might claim that their product fits a mattress up to 18" thick, but an air mattress is usually 19" thick and the sheet maker lied. So you buy your bedding at the dollar store, sew bra hooks to it, and tie it on with elastic tape.
This all lasted from September last year to April this year, so Christmas goodies were on sale to make room for Easter goodies. Teddy bears were half price, so I adopted one.
These pics were taken before I widened the bunky board.
BTW an air mattress costs 60 bux at Wally World and is expected to last a year. That works out to 5 bux a month and the only snooze cheaper than that is on the floor. A water bed has to last 8 1/3 years to get down to that number, and most other beds are twice that much.
