On parts and builds

  • The seat and backrest are straight boards in the prototypes. However, if you have better machines at your disposal, you should have butt patterns and bends in the backrest and at the front end of the chair leg. Of course, it is also possible to incorporate other interesting curves into the backrest and seat within the tolerance

↑ If you have the option of making the seat in this way, then you don’t have to use the 5° spacers.

  • The chair uses the Elephant Rods (095.1-095.5) from the Ikego parts catalogue. The makes of these parts here use the maximum tolerance of 15mm – the aluminium tubes are 50mm thick. The reason for this is that the contact surface between the legs and the seat absorbs all the forces that accumulate in the chair. The larger the contact surface, the better. See also the next point. To create these contact surfaces, the seat plate is also 10 mm wider on each side than is describe in the part documentation of the seat board  (121.1). So in total: 440×470 instead of 420×450.
  • A chair must be able to carry a lot of weight. The components should therefore be very sturdy. The Elephant rods should be able to be screwed very firmly to the seat and the seat must be very strong because this plate stabilises the chair.
  • Part of the design is a 4mm thick disc (004.1), which has the same circumference as the installed Elephant rods. The disc is necessary to adjust the length of the legs resulting from the 5° angle. See the documentation for the component with the 5° angle below.
  • Anyone is free to adapt this chair further, e.g. to make a smaller version for children, which would then even manage with plastic tubes. Kids version!
  • Some of our prototypes show colored bands/colored rings. These are there as placeholders to show that the inserts in the aluminium tubes can also be colored (and colorful), or that you could, for example, cover or highlight the joints between the individual rods with colored silicone bands or adhesive tape. ‘When it comes to the possibility of disassembling something, emphasise the connections!’
