"MONO chair appears as a rectangular case and opens up into a back, seat and armrests in only one movement of the hand. When closed, the chair is only 12 cm deep. The seat is spring-loaded, and returns to the casing simultaneously with the backrest and armrests."
The armrests don't look particularly comfortable, so just sit De Stijl.
It's also available in non-Mondrian finishes, like Birch, Beech, Ash, Maple and Oak.
Mono is in production by auditorium furniture manufacturer Hamari.
