The Boyd Flotation Galaxy Free Flow replacement waterbed mattress bladder will fit inside an 8" deep fill softside waterbed mattress. You can control your level of firmness by adding more or less water.
A Galaxy Free Flow replacement waterbed mattress bladder will fit inside your existing 8" deep fill softside waterbed foam cavity. A free flow mattress provides for a greater deal of motion than a fiber filled waterbed mattress.
We recommend that when you purchase your new softside waterbed mattress bladder that you add Blue Magic Waterbed Conditioner at the time of filling. By properly conditioning your waterbed mattress each year you protect the vinyl, fiber and foam. Waterbed Conditioner also controls odor causing gases and slime forming bacteria.
