What a cave bed can do to a child’s imagination is priceless. Arched and shaped like a cave, it can be anything the child wants it to be. Inside it are shelves and a lamp, to encourage reading.
The top part of the “cave” is covered in fabric, which can be removed at any time while the side has a drawbridge providing the illusion of protection (from dragons and beasts). On a more functional side, the drawbridge serves as a table. The cave bed also offers privacy, a secret hiding place from ghosts and goblins in dreams.
A standard sized kids mattress should fit it.
