The Joker Desk-bed is a transformable system made up of a desk and a bed. An easy movement enables you to pull down a bed ready for use without moving any objects from the desk. Optional: Bookcase cm h 89x214x29. (Priced with mattress: $3367.00 Too rich for my blood! The basic concept seems hackable though - albeit, without hydraulic lifts!) It is a very good tiny-house sized design, especially if climbing a ladder to a sleeping loft is impractical.
