Pneumatic bed assembly

A bed assembly comprising:

• a box spring support structure including a resilient top surface and deformable wall means supporting said top surface;
• at least one air mattress supported on top of said box spring, said air mattress having an overall firmness determined by the quantity of air in said mattress and a port for admitting and releasing air to and from said air mattress;
• means for adjusting the overall firmness of said air mattress by adjusting the amount of air in said air mattress;
• said adjusting means including at least one flexible walled balloon, conduit means for connecting in fluid communication said balloon with said port of said air mattress, and means for applying pressure to said balloon to transfer air between said balloon and said air mattress;
• said pressure application means including a housing with a top wall, a bottom wall, a plurality of upright side walls, and means for moving one of said walls relative to the other walls, said moving means including means for holding said movable wall at a fixed position after a desired overall firmness is selected, said housing being supported below and within the outer perimeter of said box spring support structure.

A box spring assembly for use with an air mattress assembly comprising:

• a box spring for resiliently supporting the air mattress including a bottom surface, a top surface, deformable side walls and a plurality of springs supported between said top and bottom surface;
• means located within the box spring for adjusting the overall firmness of the air mattress by adjusting the amount of air in said air mattress;
• said adjusting means including a set of flexible walled balloons, conduit means for connecting in fluid communication each of said balloons with a port of the air mattress, and means for applying pressure to said balloons to transfer air between said balloons and the air mattress;
• said pressure application means including a housing with a top wall, bottom wall, a plurality of upright side walls, and means for moving one of said walls relative to the other walls, said moving means including means for holding said movable wall at a fixed position and exerting a fixed pressure on said balloons whereby a desired overall firmness in the mattress is selected, said housing being supported below the top surface of said box spring and within the outer perimeter of the box spring.
