Designed by Charlotte Perriand for Cassina, 529 Rio consists of six wedge sections of varying radiuses set out of alignment alongside each other with an outside edge of solid natural oak or open-pored black-stained oak. The six non-aligned sections, forming the table top with a hole in the centre, are available in three different finishes: rattan with natural oak edges, white Carrara marble with natural oak edges and black Marquiña marble with open-pored black stained oak edges. Six legs in the same finishes as the edges form the base of the side table. The base of the table has six legs available in the same finishes of edges. It was designed in two different sizes by Charlotte Perriand: Cassina has reissued the first project of 1962, designed for Jacques Martin's home in Rio. Later, this table was adapted by the designer for the Japanese Embassy in Paris, increasing its size.
