The completed sofa
In the back of the sofa I built a well to store the cushions for the bed
The well
The front piece has a 3/4 lip to hold the cushions and hide the hinges
It lifts up to clear the draws when setting up the bed
The back piece lifts up to form the front leg of the bed
Both pieces are lifted up and pulled over to form the base of the bed
The base opened up
The cushions are arranged as such and you have a bed
If you need any more info just ask. good luck.
