Planning your room
Room layout
considerations.
Castaway Bed is designed to fit comfortably in most standard bedrooms while giving each sleeper more personal space when open. The main planning consideration is leaving enough room to move comfortably around both sides.
Mattress compatibility
Works with any
standard Twin XL.
Castaway Bed is designed to work with two standard Twin XL mattresses. When the beds come together, the mattresses align to create a complete king sleeping surface.
Recommended mattress height: For the best experience, we recommend mattresses between 10–14 inches in height with similar firmness on both sides. The custom 31" center platform mattress is included with your Castaway Bed purchase.
