Abstract
An inner spring mattress with firmness adjusting air bladders, the inflation pressure of which defines the mattress firmness. A plurality of inflatable bladders are disposed within the mattress. The bladders may span the entire width of the mattress. Alternatively, the width of the mattress may be divided in two using two bladders placed end-to-end providing independent firmness control for both sides of the mattress. Still further, bladders may be grouped together to form firmness zones, and the entire process may be computer controlled.
