Furniture Design Pebble Outdoor Sofa by Mattice Boets Inspired by the tactility of pebbles, Pebble is an outdoor sofa made from white-grey cork. It consists of various pebble-like cushions that perfectly fit together. The design translates the tactility of pebbles, the urge to feel and touch, into a pebble-like composition that everyone can experience at any time of the year. The sofa can be left outdoors permanently and is resilient against natural weathering. The use of cork is a premier in outdoor furniture. It allows a new design language to emerge, is lightweight, and shows the potential of using cork beyond indoor use.
