Whereas 1930s furniture had been heavy and ponderous, Day’s post-war designs were light on their feet and economical in their use of materials. A minimalist frame was adopted for the 675 Chair, a dining chair with a slender floating moulded plywood seat back.

In September 2014 Case Furniture launched an authentic new production of Robin Days’ classic 675 Chair (1952). An example of the original production was sourced as the template for development work carried out in consultation with the Robin and Lucienne Day Foundation. It was awarded a Design Guild Mark by the Furniture Makers' Company in March 2015.
