This side table or coffee table is made of fiberglass (Fiberlite) in Black. It is square with an indented tabletop. It was designed by Mario Bellini for C&B Italia in the 1960s. This table is the large size, 84 x 84 x 36 cm. We have other sizes and colors. Signs of use and some slight discoloration. This piece is attributed to the mentioned designer/maker. It has no attribution mark and no official proof of authenticity, however it is well documented in design history. I take full responsibility for any authenticity issues arising from misattribution
