Abstract

A foldable infant mattress system with a sleeping recess. A head mattress section is hingedly connected to a foot mattress section. Each mattress sections include an end wall and two laterally spaced apart sidewalls traversed to the end wall. The foldable infant mattress system is deployed in a flat position for sleeping and foldable into a closed position for carrying. In the flat position, the end wall and sidewalls of each mattress section together form the recess which contains an infant to a sleeping area. The walls are of sufficient thickness to allow for sound structural support and effective restraint of the infant. In the closed position, the mattress sections form a compact, easily carried assembly. A closing device such as a combination of straps and a snap is used which also forms a handle for carrying the mattress system. The mattress system is constructed of a foam material which is air permeable.
