Sleep Number, ahhhhhh
We bought one for our bed in the house and love it. Our son moved out and took his queen mattress with him. We found a deal on a Sleep number and got one for his old room, just in time for him to move back in.
After a brief discussion and a lot of measuring, we put the queen Sleep Number in the camper. I had to lengthen the platform by adding some 5/8" plywood to the existing frame. I sanded the edges and screwed the plywood up and down to the existing base.
It's not any heavier than the other custom mattress we had made for the camper. We do have to prop it up when we are getting something large out of the under-bed storage.
It's well worth is to us.
