Don’t get fooled by the its look! It may looks like a real stone that will hurt your butt when you sit on it, but it actually made from a soft material. Designed by Matthijs Kok, this chair is made from polyurethane soft foam with clay grains and pigment to create the raw stone texture. The result is amazing, it looks hard and rough but it feels soft and comfortable. You can see the video here. More description by Matthijs Kok:

The Stone Foam Stool arose from my fascination for Installation Art. The perception, interaction and contradictions, characteristic of Installation Art are brought together in this stool. A stool with a hard look, which is unexpectedly soft.

After a material research of polyurethane soft foam material I developed a recipe that creates stone foam. Adding clay grains and pigment to liquid soft foam gives the expanded foam a raw stone texture.

The silicone mold of a negative of soapstone is filled with the mixture. The mixture inside the mold increases sixteen times in volume. 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.
