Made this cot sized Murphy bed for my son. We have very little space and needed something that could be a bit more versatile that a regular bed.   We bought all the plywood from Bunnings for $54 and all the hinges and support wood was rescued from old building materials we got for free. It&#x27;s all screwed together using chipboard screws.  Took one day to design another to buy and collect the wood and another day to put it all together.
