25 May 1915 to 9 November 2010, was a British furniture designer. Died at the age of 95. Day is best knownfor his injection moulded polypropylene stacking chair, of which over 20 million have been manufactured. It was one of the first pieces of furniture to fully use the mass-manufacturing opportunities of injectionmoulding. It is now so iconic, it was selected as one of eight designs in a 2009 series of British stamps of "British Design Classics". He rose to prominence during the 1951 Festival of Britain. Day was a past winner of the Chartered Society of Designers Minerva Medal, the highest accolade the Society can offer and is awarded for a lifetime achievement in the field of design, and is Patron of the South Coast Design Forum. His wife, Lucienne Day (1917 to 2010), was a noted textile designer. Robin and Lucienne Day established themselves as Britain's most celebrated post-war designer couple, and have often been compared to their US contemporaries, Charles Eames and Ray Eames. An exhibition of Lucienne Day's textiles and Robin Day's furniture, "Robin and Lucienne Day: Design and the Modern Interior", will be held in spring 2011 (26 March - 26 June 2011) at Pallant House Gallery in Chichester-the city where the Days retired in 2000, in order to be closer to their Sussex cottage, where Day spent much of her time in the garden.
