Sumo was made for the EcoDesign Exhibition in Helsinki, Finland. The chair is covered with Tärnsjö leather and filled with buckwheat hulls. Tärnsjö leather is organically tanned using vegetable-based processes for minimal impact on the environment. Buckwheat is an ecologically cultivated herb used in cooking and baking. Buckwheat shells or hulls are usually considered a waste product.

This ‘after-dinner chair’ is an experiment using renewable and biodegradable materials that, to a large degree, are waste products from food production. Basically, the chair has the same shape as a regular chair, but is then filled to the limit with padding to create the unique Sumo shape.
