HygroShape is the first concept for self-forming furniture. Using the natural properties of wood, pieces of furniture are made flat and unfold by themselves when unpacked. This programmed change in shape results solely from hygroscopic shrinkage, a natural property of wood. It occurs silently, without human intervention, tools or assembly instructions, and takes place evenly and reliably. Once formed, the parts lock mechanically, creating dimensional stability while maintaining an active ergonomic function through small harmonic movements. The project represents a paradigm shift in design and manufacturing processes for wood: By using material programming, a previously untapped potential of wood as a renewable material is activated, enabling more sustainable processes and applications. This brings with it a new material and design language in which the natural qualities and properties of wood are directly reflected in form and function.

The spin-off company hylo tech continues to explore the potential applications of this technology, starting with furniture design and ending with load-bearing structures.

The curved wood components are made exclusively from locally sourced maple wood, bonded with wood glue (Henkel LOCTITE HB S309 PURBOND glue). The forming process is initiated solely by the natural extraction of water during air drying.
