Tray support for a mattress
A mattress core support system in the form of a padded tray with a rigid bottom surface. The tray is comprised of four foam sides, providing edge support for persons sitting on the edge of the mattress, and containing therein a mattress core. The system is compatible with (and sized for) all standard mattress cores, e.g., coil spring, foam, foam/coil composite, and all known sizes. The mattress avoids the need for flipping and the associated increased cost of a two-sided mattress by including as its bottom member a rigid platform.
