The ONYX sofa is a three-meter-long seat made of carbon fiber and Volvic lava stone. Presented for the first time at this year’s Milan Design Week, the ONYX sofa is the demonstration of a made to measure furnishing concept dreamed up by Peugeot Design Lab. The sofa is the latest in a series of unique pieces of furniture which always respects a common idea: the union, via a pronounced clear cut, between hyper-technological materials like carbon fiber, glass and aluminum, and raw and natural materials like rock, wood and stone. This specific ONYX sofa has been priced at $185,585 USD. Since the sofa is made to measure, pricing will depend on the cost of the materials chosen by each client. This particular model took designer Pierre Gimbergues a total of 70 work days to make. For more information head on over to Peugeot Design Lab.
