This apparatus for supporting a human body for improved blood circulation comprises a frame, a pair of endless flexible belt assemblies having transverse roller members, means for mounting the belt assemblies on the frame to form laterally juxtaposed body support spans each consisting essentially of an upper stretch of the roller members of a belt assembly, means for moving the belts to cause the roller members to move along the body support span of each belt assembly, and track means for supporting at least some of the roller members of the laterally juxtaposed body support spans in an angular position toward a Y-shaped relationship for a partially cradling body support effect. |
