Two Columbia Road is a London based gallery specializing in a broad range of collectible furniture, associated design, works of art and photography from Scandinavia, Europe, and North America. Sometimes they have extra ordinary chairs for sale.
Here are two clearly Dutch 20ies Red Chairs they offer for sale. However 2 Columbia Road attributes them to the La Haye School, which to my view is wrong. The La Haye School is French for Haagse School or Hague School which is only about painters and not about furniture. Maybe they should be attributed to a member of De Stijl Group whose most prominent Chair designer was Gerrit Rietveld. Maybe this is a design by Theo van Doesburg or by J.J.P. Oud, both members of De Stijl who also designed chairs.
