ABSTRACT:
A mattress includes a flexible tube having a pair of major surfaces alternating with a pair of side surfaces with marginal portions of the major surfaces extending beyond the side surfaces at each end of the tube. The marginal portions are bent toward each other and lap sealed along seams extending substantially between the side surfaces to form the end surfaces of the mattress. At each corner an insert is disposed along a line where the end surface approaches the side surface and is attached thereto by a continuous lap seam having substantially parallel sides extending substantially between the major surfaces. An associated method includes the provision of a special mandril for heat sealing the insert.
