Oldsjö Hultgren Design is a collaboration between Jenny Oldsjö and Ragnar Hultgren. Their perspective as designers is that of problem-solving, with the starting point in the development possibilities of different materials. They consider themselves to be designing product innovators.

The Striding tiles are made out of aluminium sheet, but the designers use the same principle for other materials (like the 4th image). Three different designs corporate the same M.C. Escher style of connection between the tiles. This small collection is still a prototype, Oldsjö Hultgren Design is searching for a manufacturer.
