Chick 'n' Egg Chair

Chick 'n' Egg Chair is a lightweight seating furniture made entirely from corrugated cardboard.
It was designed and developed at the Chair of CAAD, ETH Zürich.
The form was completely 3D modelled in McNeel Rhino and then further processed in Grasshopper. The parametric setup allows the piece to be rescaled to any desired size, resolution and material strenght. Although the chair was initially designed for kids it can easily be adjusted. So far two versions have been cut and built - one for small children and another one for grown ups.
