Rita is a multidisciplinary design studio in Montreal. Their work ranges from graphic design in pamphlets and books to the design of furnishings and interiors. Their Folder Chair popped out at us not just for its bright yellow color...

Rita's stackable Folder Chair is shaped like file folders. When stacked, the chairs have "tabs" at different locations that'll remind you of the interior of your filing cabinet. When you're trying to relax away from the office, these might not do the trick, but in a home office they could be a cheery addition.
