This cleverly designed Som chair is by industrial designer Eva Dugintseva. It's made from recycled polystyrene and was produced on a Kuka 3D printer. The chair doesn't require any fasteners to assemble; you simply slide the parts together.

Finished Product:

"It can be used both outdoors and indoors. The chair has the same length of the back and bottom parts, so it is possible to turn it upside down if needed. To remove the leg, lean Som forward and pull it out. The plastic surface does not require special cleaning products and can be washed with water and soap. Som chair can hold up to 150 kg and pigments in the plastic do not fade even under the direct sun."

There's no word on whether it will see production, but the design did win a Best Industrial Design of Russia award.
