Build Your Own Horizontal Murphy Bed Plan Queen Size Wall Bed Plans DIY Furniture. The plans for this Horizontal Queen Sized and double-sized Murphy Bed include a Material list. This is the same design as my Vertical Murphy bed but lays horizontally for rooms where this design will work better. This is designed so that you do not need to buy an expensive metal frame. You build everything yourself. I absolutely love this design. I have one in my office to be used by guests when they come. I have 6 of these in my cabin. It is great, they look good when they are folded up and at night, I have an extra 6 beds that can pop out when I need them without taking up space during the day. I even have one in my ice fishing shack!
