Abstract: A system of padded covers that are attached to adjustable split bed rails, and which are pivotally engageable so that the bed rails may be adjusted with a bed without having to remove or reposition the bed rail covers. The bed rail cover system includes a pair of upper covers, which are mirror images of each other, so that they fit on the upper bed rails adjacent the head of the bed on both sides, as well as another mirror image pair of lower covers fitted over lower bed rails adjacent the foot of the bed on both sides. Each upper cover includes two sides having an upper end and a lower end. The upper end refers to the portion of the cover toward the head of the bed, and the lower end refers to the portion of the cover toward the foot of the bed. The lower covers each include a pair of longitudinal sides that form a slot therebetween, at an upper end. The lower end of the upper cover slides into the slot formed between the longitudinal sides of the lower cover.
