The perception, interaction and contradictions are brought together in the Stone Foam Stool by designer Matthijs Kok. This stool looks hard but it is unexpectedly soft as adding clay grains and pigment to liquid soft foam gives the expanded foam a raw stone texture. During expanding, the stone foam takes over the shape of the mold. The clay granules are soaked from the casting and hereafter the stone texture appears. Finally, the casting is finetuned with multiple gray shades for a more natural result and the chrome legs are attached to the seat. So, don’t let the chair deceive you – it’s as soft as a baby’s backside!
