Side cabinetry – most people are interested in shelving or drawers or wardrobe cabinets alongside their new Murphy Bed.  The sizes of these items vary, of course, depending on what you need for that space.  Try to do business with a company that offers 100% custom products.  If you have 21” on either side of your Murphy Bed and you want some shelving on either side, then the cabinetry company should be able to fabricate their cabinets or shelves to fit precisely.  If they offer “pre-made” items that are only available in 24” or 30” wide, then you are not dealing with a custom shop.  Their product may be fine, but if your needs are unique, they may not be able to meet them precisely.
