How to turn matresses into a sofa?
I have two fairly old and unused doublesided spring mattresses, measuring 190x90x19 cm each.
I am thinking of turning them into a compact convertible sofa that would allow me to sit during the day and sleep when necessary.
Could anyone come up with an idea of a chassis to hold the matresses, that would make the conversion process as easy as possible?
Was thinking about a chest & rails stuff, but never came up with anything substantial, as my designs were lacking proportions (too deep, too tall, that kind of stuff).
