Composite inflatable mattress

Abstract

A composite inflatable mattress includes a bottom layer, an air cushion layer and an air pressure adjustment unit. The bottom layer defines a bottom space. The air cushion layer is disposed on the bottom layer and includes an outer casing, and a partition plate disposed in the outer casing and cooperating with the outer casing to define two air chambers thereamong. The air pressure adjustment unit is mounted to the bottom layer and the air cushion layer, and includes an inflation mechanism mounted to the air cushion layer and in spatial communication with the two air chambers, an air pump motor mounted in the bottom space and in spatial communication with the inflation mechanism, and two pressure relief valves mounted to the outer casing and in spatial communication respectively with the two air chambers.
