An occupant support such as a bed 20 includes an articulable deck 34 having an upper body section 44 and a section 46 or 74 longitudinally adjacent to the upper body section. The upper body section is pivotable relative to the adjacent section about a laterally extending upper pivot axis. The upper body section may be pivoted to angular orientations between a substantially flat angular orientation and a maximum angular orientation. A siderail 86 affixed to the upper body section, includes a grip 102 having an ascending orientation relative to the upper body section. The grip is longitudinally bounded by a siderail back portion 106 located behind the grip and a siderail front portion 110 located in front of the grip. At least part of the front portion has a non-ascending orientation relative to the upper body section.
