Addi is the first chair added to the Trikka catalog. It is comfortable and very modular. There are already several alternate builds for this chair using the same parts. Addi is a collaboration of the designers Lars Zimmermann and Max Cuppens.

Building + parts
- The chair stacks several bars on to each other. Depending on how thick those are (within the standard tolerance) the bolts need to be longer or shorter. That is why there are several bolts in the parts list. You don’t need all of them. Which one you need will depend on the actual thickness of the material.
- The parts list contains regular nuts (089.1) and wing nuts (088.1). You do not need both. You just need nuts. In general many of the fasteners shared in the parts list can easily be replaced with others. Something you’ll see clearly, when you start building your version of Addi.
- If you choose thin material for the bars the stand area of the chair gets smaller. In this case longer beams (079.1) should be used between the two sides of the chair. Shorter beams (078.1) are sufficient for thicker bars. Both beam sizes are listed in the parts list but of course you only need one size when you make your chair.
- The parts list adds a part (073.1) that is only needed for Alternate Build 2 . This part is not needed for Addi One.
- Alternate Build 1 and 3 use fewer different parts. Most importantly the two wooden backrest parts (076.1, 081.1) are not needed.
- In a way Bengi the bench can be seen as a 4th alternate build of Addi as well.
- The spacer (072.1) should have the same thickness as the bars used. If you get it from a different source you need to bring the level of the bars and spacers to the same level. Maybe washers help.
- The spacer (034.1) determines the angle of the backrest. 40 mm has proven to be very good to achieve a comfortable standard backrest angle. If you lengthen or shorten this spacer within the standard tolerance the angle of the backrest will change. This is one way to adjust it.
- The original post recommends to mill in a butt pattern and back curve into the seating plate (080.1) and backrest plate (081.1) which is a good use of the standard tolerance.
