ABSTRACT:
A mattress construction includes upper and lower structures defining generally parallel planes, and coil springs operatively connected to such structures and located between those lanes, and with at least one of the upper and lower structures including a first tensionable sheet; a member or members extending at the periphery of the mattress and connected with the first tensionable sheet to interact therewith and transmit force for tensioning the tensionable sheet; and a device for adjusting the tension exerted by said member or members. The mattress construction also enables treating of a patient having a spinal condition for which traction is recommended by suspending the patient's body to extend generally horizontally on a "trampoline" grid mattress surface which interacts with the mattress border perimeter structure to create a surface lift and therefore stretch reflex on the patient's body. This surface lift is transmitted vertically in a rebound proportional to the weight and movement of the body or bodies on it to further transmit forces horizontally to the perimeter border surface and substructures creating an elongation and decompression of the patient's spine.
