Folding Bed Bench (Hidden Cot)

I found a version of this bed at a local antique barn. I loved the idea of it and couldn't find any plans online. So here is my interpretation. 
This bed works well for small basement suite my wife and I rent. We love having friends over, but if anyone needs to sleep over they are usually subjected to the floor. This handy bench solves the problem and provides a conversation piece at the same time. 

This project posed a few complications. Precision and accuracy are necessary. Replicating 32 1x7/8"x24 pieces with 3 holes drilled in the correct spot is difficult. 
Hardware is expensive, again everything needs to be the same. I tried to avoid using washers and discovered the leg pieces flexed and jammed against themselves. Washers solved this issue. 
Finding material that can flex but is still strong enough. I chose this canvas but it will still need to be reinforced with a cotton belt along the edge to prevent the grommets ripping out of the fabric. 

         What I learned: 
No need to replicate exactly what you see, I made the legs 1x7/8x24" because that's what the original was. It would be simpler to do 1x1x24 
Mock everything up first
Sand after everything but before applying a finish. 
Be flexible and don't stick to the original design if it doesn't work. 

I hope to make another in the future and will post a more detailed instructable.

Hope you all enjoy the photographs.
