Hi Callakn,
Take a look at the Ovano system (link below). Basically a birch ply system that you can store flat when not in use if required. Though not sure you would want to remove once fitted as it looks very flexible. Key feature being that can use either with or without the Kombi seats fitted. If seats removed then the bed rests on some legs that also double as locking supports for the bench seat position. Means you have the space that the seats would normally take up and a bench seat for the day. Then easily pull out the bed for night.
