The king platform, and it accepts a headboard mounted left or right without a change to the base. Edges are rounded rather than square, a small mercy for shins in a dark room, and mattress retention is built into the frame so bedding stays put through nightly use. Accessible king rooms take a version on the same visual program at a lower deck height. Buy it alongside the queen and double platforms and a mixed floor stays consistent. Minimum order of 10 units, priced by quote.
