Abstract: A bedding arrangement having a versatile mattress foundation which is designed to be utilized in combination with an accompanying inflatable mattress. The mattress foundation has a primary support structure for supporting a mattress and any loads imposed thereon, and a compartment is defined therein which houses an air compressor. The primary support structure includes a first area of support structure extending substantially the full height of the mattress foundation and a second area of support structure extending from the top surface of the foundation to only a portion of its full height, and the compressor compartment is positioned below the second area of support structure. The air compressor is pneumatically coupled to the inflatable mattress to provide a very convenient control over its internal pressure and resultant firmness. In one disclosed embodiment, a control panel is positioned on one side of the foundation to provide for convenient control over the compressor and mattress internal pressure.
