DIY Murphy bed made from solid wood

My husband used the plans from this website to make a single Murphy bed. He didn't make any changes, save for building the frame out of solid poplar and using birch plywood for the flat surface the mattress sits on when it's unfolded. We trimmed it to mimic the the lines of a built-in in the same room, and stained it Jacobean to make it look dark. It's a solid piece of furniture and is saving us tons of space.
