Make the simplest platform I could . I’m using a futon mattress (air mattress always seem to suck ) so I made the platform fold in two spots so I can roll the mattress up with sleeping bag on it and still be able to put stuff on top of the mattress and as a bonus it will sit angled when folded half way making a lounge to sit and chill . Found a piece of 3/4” ply in the back of the warehouse at work that had piano hinges on it so total cost so far is 0$ . The sliders are just pieces of hardwood that I did a round over on and sanded super smooth and smothered in paste wax . It slides super easy actually to easy because it bangs back and forth when driving . Took the scraps I had left over and mocked up a box for the sides . I will pick up some nice birch or other nice plywood to make them out of .
