Celebrated Danish design duo Nanna and Jørgen Ditzel were known for pioneering new materials and that spirit infuses Mater’s eco-conscious reimagining of their 1955 chair. Ocean’s slatted contours, originally fashioned in wood veneer, are composed of used fishnets (primarily from Denmark’s west coast) and recycled hard plastic—each one using 960 grams of ocean plastic waste. With its steel frame in a gunmetal finish, the seating comes in black or sand hues and is made and tested for outdoor use as well. Such sustainable thinking is a hallmark of the Mater brand and was honored with a 2019 Wallpaper Design Award.
