When wood dries two things happens, it shrinks and it bends. We want to use these properties to both fabricate and design a chair.
Depending on where the tree has grown and what it has been exposed to it will act different when dried. Because of this every chair gets a unique appearance and look even if they were produced in the exact same way.
Usually wood is dried slowly to avoid changes in shape. We want to favor woods own will to change shape and therefore we dry it rapidly and uneven. The wood is dried after the chair is assembled and not before as common and we are using greenwoodworking techniques, where the fresh wood parts shrinks around the dry tenon to frame the construction.
