A body support apparatus, for example, a bed, includes a support surface defined by support members. Each support member is mounted for movement in a direction substantially normal to the support surface. Support members are so arranged that movement of any one of the support members in a direction substantially normal to the support surface and beyond a threshold distance relative to an adjacent support member causes movement in substantially the same direction of said adjacent support member. No movement of a support member is caused by the movement of an adjacent support member when the distance of relative movement is below the threshold distance. The support members are resiliently urged towards an unloaded position, by tension springs. |
