Wooden beds with a high head and footboard, so named as the ends are often shaped like a classic sleigh, joined with deep sidebars within which the mattress sits, hidden from view.
As they are partially enclosed, sleigh beds feel comfortable, benefit from some draught-proofing and carry a sense of privacy. They look as good against a wall as free standing within the room and are a popular choice when space is limited, as a sofa/bed option for guest rooms, as day beds in dressing rooms, or beds doubling up as sofas for children and teenagers.
Although sleigh beds are mostly made in wood (upholstered or not), some metal day beds are shaped similarly.
