Clever DIY Sofa Bed - Folds out in 6 seconds!

This week's idea is to build a sofa bed out of plywood and I wanted to do three things. First of all, I want it to be actually comfortable. Most sofa beds I slept on were super uncomfortable. So I am building the whole thing around an actual bed mattress. The second thing is I wanted to have storage for the bedding so you can just put it in there close this lid and then that's it. And the third thing I want the mechanism to change it from a bed into a sofa to be very, very quick and easy. Well, I have three days to build this. Let's see if I can do it.
