The Lori Wall Bed will work with any standard mattress up to 12 inches thick. If you wish to store a comforter, bed spread or other thick bedding on the mattress, ensure it adds up to a total of no more than 12 inches in thickness.
If you need to use a thicker mattress, it's not too hard to add a few inches of thickness while building your bed.
While the bed will work with any mattress, we don't recommend using a memory foam mattress if you can avoid it. These mattresses are incredibly heavy to lift; choose a conventional innerspring or latex foam mattress if you can.
