A hospital bed comprising: a frame; a plurality of extendable patient support panels mounted to the frame, each patient support panel including a central section and at least one side section selectively movable laterally towards and away from the central section; a movement transmission assembly including at least one transmission member connecting at least two of the movable side sections for laterally moving at least one of the movable side sections when another one of the movable side sections is moved.

A hospital bed includes a frame, a plurality of extendable patient support panels mounted to the frame, and a slide mechanism. Each patient support panel includes a central section and at least one coplanar side section selectively movable laterally towards and away from the central section, where the at least one coplanar side section is slidably connected to the corresponding central section. The slide mechanism allows sliding movement of the at least one side section relative to the corresponding central section.
