ABSTRACT:
There is a support module for a posture support device such as a bed mattress. The module comprises upper and lower frames (3A, 3B) connected together by linkages (3C, 3D) which in use of the module within the support device are adapted upon activation by an external control (3H, 3J) to displace the frames (3A, 3B) between a collapsed configuration and a spaced apart configuration so that the posture support device can be adjusted between a soft support and a firm support. The module may be fitted between rows of conventional innersprings during manufacture of a conventional bed mattress,
