I have a double size floatation mattress bed with black metal frame for sale. The mattress is in good shape no stains etc. The bed looks like a regular bed but it has water tubes in it, but it is not as wavy as a waterbed. The tubes are in excellent shape and it has never leaked or been patched. The frame has a few scratches on the headboard that faces the wall. I really need to sell this bed due to my husband having cancer surgery and I can use all the extra $$ I can get while he recovers.
