Abstract
Corner structure for a waterbed mattress and liner in which a cornerpiece is formed as a monolithic structure with a relatively thick base plate and relatively large ridges or cleats projecting from the front surface of the base plate. The base plate has a peripheral sealing area which is affixed by heat sealing to the walls of the mattress or liner to form the corner, and the base plate is formed of a material which is pliant enough to conform to the contour of the mattress and tough enough to resist puncturing. The ridges or cleats help to keep bedsheets in place on the mattress.
