Twentytwentyone is a respected design retail company set up by Simon Alderson and Tony Cunningham in 1996. As well as acting as exclusive agents for international design companies, twentytwentyone produces its own collection of furniture and accessories.
Robin Day first collaborated with twentytwentyone in 1999 when he contributed a design to the Childsply charity project. He went on to design the Avian family of seating, reflecting ideas inherent in his 1951 Royal Festival Hall Lounge Chair. In 2006 Lucienne Day worked with twentytwentyone to develop reissues of four of her midcentury tea towel designs.
In 2012 twentytwentyone launched a new production of Robin Day's Reclining Chair (1952), which won Wallpaper magazine's Design Award for Best Reissue.
In September 2014 twentytwentyone curated and hosted At Home with the Days, an online charity auction of items from the Days' own homes. All proceeds went directly to the Foundation to help fund the new Robin and Lucienne Day Foundation digital archive.
twentytwentyone celebrated the 100th anniversary of Robin Day's birth in 2015 with a Centenary Edition of his Reclining Chair, with upholstery selected by ten of the country's leading designers.
In 2017 twentytwentyone launched a new production of Robin Day's Slatted Bench (1954). The company celebrated Lucienne Day's centenary with Day for Flowers, an exhibition of floral displays by leading figures in the design world using a new Limited Edition of Lucienne Day's 1966 designs for Flower Bricks.
As part of their 25th anniversary celebrations in 2021, twentytwentyone launched three new Robin Day products: a special edition of the Reclining Chair with walnut armrests and a richly textural heritage Mourne Textiles weave, a limited edition of the Transparent Table created in the early 1960s as a one-off piece for the family's living room, and the first-ever new production of his Chevron Chair (1959).
