The 19 Outdoors Dining Arm Chair, designed by Butterfield Brothers for NINE, is an outdoor chair. Made in powder-coated aluminium, this dining chair is part of the outdoor collection 19 Outdoors inspired by the charity project 19 Chairs. During the Covid-19 lockdown, the design duo designed and made 19 chairs in 19 days in their south London garden. The chairs were then sent to different designers who were challenged to reinvent or redesign the design with an older person in mind. They were then displayed at an exhibition in London and in parallel there was also an online charity auction, where all proceeds were donated to Age UK.
