Abstract: A cot is designed to be used positioned against the side of a parent bed. A folding leg arrangement enables the height of the cot sleeping base to be matched with the parent bed. The leg arrangement uses support struts and sliding connections to the cot support base to maintain its footprint at all heights. The end walls and side walls are all foldable relative to the sleeping base. The cot can be folded flat by folding the side walls onto the base and the end walls in on top of them. The leg arrangement can also fold flat. One side wall can be folded out to lie on the adjacent parent bed, bridging the gap. It can also be folded at half height to provide partial access when upright, or a shorter bridge when folded out.
