Abstract
Abstract A cushion of the type having a plurality of forms of resilient material has a core of foam rubber or its equivalent, with a cross-section preferably suggestive of an I beam. The foam rubber slab in the position of the web is normally horizontal, with this characteristic ''''I'''' cross-section extending substantially throughout the length of the pillow. The foam rubber core is surrounded by a padding of preferably fibrous batting, and this assembly is surrounded by a cover.
