Delta is a collection of chairs that stands out for its minimalist design. A single line defines the shape of the backrest and the seat that conceals a self-weighing mechanism. The levers for adjusting the height and tilt of the seat are integrated in the chair. The backrest is available either upholstered or in breathable mesh. It comes in two heights: high or medium. The frame, available in white or black, can be combined with a 5-spoke nylon or aluminium base or a 4-spoke aluminium base.
