Welcome mobility — via roll-around castors and a seat that swivels and tilts — accentuates the finely engineered utility of this Fiber Conference Armchair model from Muuto. Its distinctive sculptural design and long-lastingly comfortable ergonomics devised by Copenhagen-based Iskos-Berlin get a sustainable turn with the seat’s inner shell made of 99% recycled plastic. Apropos for home office and the workplace alike, the chair is fully upholstered in a choice of premium materials and fitted with a soft fixed cushion.
