A siderail assembly 40 for a bed 20 includes a link P pivotably connectable to a bed frame at a joint PF and to a rail at a joint PR. The link P has at least one reaction surface 64, 66. The assembly also includes a link R having a rail end 78 and a common end 80. The rail end of link R is pivotably connected to the rail at a joint RR. The assembly also includes a link Q having a frame end 72 and a common end 74. The frame end of link Q is pivotably connected to the frame at a joint QF. The common ends of link Q and link R are pivotably connected to each other at a joint A constrained to move substantially parallel to the reaction surface.
