The seat shell fixes two persons in a certain position. The lower seat allows one person to sit with their legs slightly open. The thigh of their right leg rests against a step forming the transition to a second seat area that is higher by the thickness of a thigh.
A helmet-like balloon that is connected with the seat can be tilted over the heads of the two people seated. Their heads thus are enclosed a narrow cylindrical space that is covered by a glass-clear plastic dome above which a transparent balloon hovers. A series of lines and stamped-out shapes made of reflective foil are placed on both the dome and the surface of the balloon in such a way that, depending on whether you concentrate on the level closer or further away from you, the elements constantly overlay each other to form new patterns.
