- Start from 
 - close both flaps (turning them 90 degrees)
 - switch the hinging side of both flaps and open carefully (there is some stretching!)
the resulting shape has a form almost identical to the cubechair. It has two superposed tiles.
 - turn 90 degrees one of the two superposed tiles (as a flap).
 - another tile becomes a flap and can be turned down 180 degrees. We get to the final shape (cubechair).
