Abstract

A mattress assembly includes an air pocket, a flow channel, pumps for making air flow into the air pocket, a valve that regulates the air flow in the flow channel and air pocket, and a controller for controlling the pump and the valve so that the hardness of the air pocket changes. The flow channel includes first and second injection flow path members that provide passages for making the air flow from first and second pumps to a first and second air pockets, respectively, and an air flow path which communicates with the first and second injection flow path members. The valve includes a flow path valve for opening and closing the air flow path, and the controller controls the pump and the flow path valve so that the hardness of at least one of the first air pocket or the second air pocket changes.
