The RAR – short for rocking armchair rod base – is widely recognised as a classic in the history of modern furniture design.
We're offering one reader the chance to win a version produced by furniture brand Vitra, featuring a white plastic seat and maple rockers.
Modernist designers Charles and Ray Eames designed their now iconic moulded plastic chairs in 1948 for a competition hosted by the Museum of Modern Art (MoMA) in New York, which sought ideas for well-designed, moderately priced furnishing for the masses.
The modernist chair, with its changeable base and optional armrests, was praised for its adaptability and awarded second prize.
The first rocking version was made available in 1950, produced by Zenith Plastics and distributed by Herman Miller.
The Eames' updated the design the same year, adding the criss-crossing wire configuration found on today's RAR chairs.
Today the RAR is largely unchanged from the 1950 version. It is produced by Vitra in a variety of colour and finish combinations.
The rocking chair we're giving away comes with a chrome-plated wire base, joining its maple rockers with its white-dyed polypropylene seat.
One reader will win the RAR chair, courtesy of retail website Luisaviaroma. The chair is also available to purchase online. Use code LC30 to benefit from an additional 30 per cent discount on sale items. Offer ends 15 January 2019.
Competition closes 6 February 2019. One winner will be selected at random and notified by email, and his or her names will be published at the top of this page.
