AN AIRY AESTHETIC

Conceived by Hoffmann Kahleyss Design, the Sinum Chair features a generously upholstered shell, combining comfort with refined aesthetics. The design is available with two base options in black powder-coated steel: a classic four-leg tubular base and a delicate, tip-toeing swivel base with an optional return function. For added flexibility, the swivel base can also be equipped with castors, providing full freedom of movement.

SUPPORT FOR ALL SEATING POSITIONS

Deriving from the Latin word for ‘pocket’, the Sinum Chair aptly takes up little space in a room – be it the conference room, the hotel room, or the dining room. The seat is characterised by a curved pocket of padding, ensuring uncompromising comfort, enclosed by either low or high armrests sloping upwards to the slightly tilted backrest that equally supports an upright and more laid-back seating position.
