A new series of chairs in modular design – with focus on using as few elements as much and for as long as possible – in exciting combinations. A chair that is easy to disassemble, so the parts can be recycled and reused for the benefit of the customer and the environment. The chair is created under the aspect of unique design, longevity and minimal transport costs due to the chairs stacking ability. The design is based on circular economy: all elements of the chair can be returned to Magnus Olesen and upgraded. The chair consists of three parts – seat, back and frame – elegantly combined with just one screw. The Ø-Chair is a sustainable chair that offers endless combination options, even when replacing individual parts over time.
