DESCRIPTION

BISCUITFOAM STOOL

This piece is a stool-type chair created through a in-depth exploration of the material properties of foam. The design eliminates the need for separate reinforcement materials, relying solely on the foam's inherent characteristics to ensure structural integrity. To achieve this, two types of foams with different densities were used in combination.

To build the supporting structure that forms the frame, techniques such as compression and weaving were utilized. Black foams were first compressed by binding them with cable ties. Then, strips of white foams were inserted into the gaps and intertwined to solidly construct the form. In contrast, the upper section where the body makes contact is uncompressed to provide a soft cushioning effect.

Visually, the structural weave and dual material properties are simultaneously expressed through the contrast between the black sponge forming the frame and the white sponge woven in between. Furthermore, considering the material's tendency to compress and sink under weight, the initial height was precisely calculated to ensure that the final seating height remains optimal when in use.
