Look on the Internet for plans to build a robot from an old computer mouse and you’ll find plenty. Really useful, huh? But, look for a set of plans for a Murphy bed and you’ll be disappointed. Oddly there are plenty of people out there searching for do-it-yourself plans for Murphy beds, myself included (both in the “searching” and in the “odd” category).
I finally found the Moddi Murphy Bed Plan and purchased their set of plans for $8. The plans include not only the exact parts that are needed (and where to buy them) but a pretty thorough set of instructions, too, including cut sheets. I was suspicious about shelling out money for a set of plans that you would think would be available anywhere on the internet but after a few days of searching and not finding such a thing, I was willing to splurge.
The deciding factor for me was not only that the plans are in one place and contain obtainable parts list, but that the entire bed (minus mattress) can be constructed for less than $400 (or less than $300 for a twin size).
