ABSTRACT:
In a water mattress, a series of interior bags or bladders are individually attached to the top and bottom layers in order to damp the movement of water. Each bag or bladder comprises a pair of disks or layers peripherally heat sealed together. Each of the layers of each of the bags or bladders are welded to the respective layers of the waterbed mattress, there being indentations on the inside of the bag or bladder layers, the outside of the mattress layers being substantially free of indentations, there being a bead formed between the welded layers which bead is extruded primarily from the bag or bladder layers.
