A vacuum formed water bed mattress providing a pair of large flat opposite parallel sides and four narrower sides joined to form a substantially right regular parallelopiped is disclosed. One of the large flat sides is made of a heat resistant material. The other flat side and four narrower sides are formed from a single sheet of material by a vacuum and temperature molding process. The two sheets are heat sealed to form the mattress. A method for the making of a water bed mattress is also disclosed.
