Abstract
A mattress for use on a hospital stretcher has an upwardly facing support surface which can support a patient. The top surface of the mattress has a plurality of small, parallel ribs which extend transversely of the mattress, and which resist sliding movement of the patient lengthwise of the mattress while simultaneously facilitating sliding movement of the patient transversely of the mattress. The mattress has bevels extending along opposite sides of the support surface, the support surface being provided on a sheetlike material which extends from a lower edge of one bevel to a lower edge of the other bevel without intervening seams extending lengthwise of the mattress. The sheetlike material is preferably a laminate which includes a rip-resistant scrim layer made of a closely woven spun polyester material and two vinyl layers disposed on respective sides of the scrim layer, the ribs being provided in one of the vinyl layers on a side thereof remote from the scrim layer.
