Metal Bed Frame

Just a quick piccie of the metal placed together on the ground, the large piece will be the frame that fixes to the top of the seat box, and the smaller one will butt up against the front of the seat with some smaller tube attached but inside the seat tubing, so its telescopic, when we need the bed out, just pull it out and fold the seat board out and over the top of it. Confused ? Honestly it will work, I think :)
