Abstract: The improved mattress of the present invention is adapted to sleep two or more people in side by side relation, each person being supported on resilient means defining a separate area of preselected firmness, the two areas being deposed lengthwise of the mattress in essentially parallel relation and being of different firmnesses. The mattress also includes resilient means defining an intermediate area between and integrally connecting the first two areas, and also disposed lengthwise of the mattress and having a graduated range of firmnesses from that of the first area to that of the second area. The resilient means may comprise elastomeric foam layers and/or sets of springs, and a detachable fluid-filled layer may be deposed thereover for improved comfort. The mattress is inexpensive and durable and offers individualized support and improved comfort for both sleepers without any sharp uncomfortable line of demarcation between the areas of differing firmness.
