Here are some photos of how our platform bed is put together. The wood is 3/4 inch birch plywood, the hinges are brass piano hinges, and aluminum angle is used to create the “box” portion and other supports.

My method for holding the platform in place: bed_support1 bed_support2 ](/2013/11/IMG_1473.jpg)

The platform is hinged in such a way as to form a seat (from before we had a drawer): seat_up

View with platform removed (looking towards the back of the van): bed_box

We have a drawer under the bed that is also used to support the front edge of the platform: bed_drawer1

Small pieces of wood “flip up” to prevent the drawer from sliding back: bed_drawer2

Pins, set in brass bushings, are used to hold the seat closed, as well as hold the platform in the “upright” position: bed_pins

Countersunk bolts are used to connect the “box” to the floor: bed_bolts

I removed the metal plate that was used to support the bench seat and replaced it with a piece of plywood with brass inserts - I have heard of others keeping the metal plate in place, and sliding the box into the angle pieces on this plate - that is a pretty slick idea! bed_plate
