Inside the wall bed, there is about 11” left of space for the mattress and bedding. With a 9” thick mattress, sheets and comforter can stay on the bed before the wall bed door is closed.
Advice : Use a single size comforter with a double size wall bed. With wall beds, you do not have to use the comforter panels on each side to “hide” a box springs. This will result in less bedding inside the closed wall bed. Similarly, use a double size comforter with a queen size wall bed.
