Abstract: One embodiment of a foot support assembly, for preventing a person from sliding down on a bed, includes a foot support member, at least one protruding member and at least one attaching member. The at least one protruding member extends outwardly from the foot support member. The at least one protruding member includes a plurality of engagement slots configured along a length thereof. The at least one attaching member includes at least one engaging slot and an adjacent elongated groove. The at least one engaging slot is adapted to be aligned with any one engagement slot of the plurality of engagement slots for adjustably attaching the at least one attaching member to the at least one protruding member. Further, the elongated groove enables the at least one attaching member to be detachably coupled with the bed, thereby attaching the foot support assembly to the bed for supporting the person's foot thereon.
