↑ Depending on the strength of your parts, you will need one or two horizontal rods to make the stool work.


↑ Optional: Add a cushion (like the subassembly cushion 400x400x10mm) to make the stool more comfortable.



↑ To add height bolt on additional bars such as 120.1 or 075.1. The height can be adjusted as required because the Tetri-Board is completely perforated in the Ikego Grid.
‘I Never Played Tetris In Ulm’ or ‘Tetri-Ulm’ is a stool that mimics the famous Ulm-Stool using simple Ikego parts.
