Make a guess: What is this stool made of? If your answer was plastic, you are wrong. It is made of steel!

Designed by Oskar Zieta for Danish brand HAY, the ‘Plopp’ stool is made just like a balloon: The stool takes its shape when air is shot in between two ultra thin steel plates cut into the shape and welded around the edges.

This unique product received the Design Award of the Federal Republic of Germany in 2009. Organized by the German Design Council, this price has the highest distinction in the field of design in the country. Plopp also received Red Dot Award in 2008 and Forum AID Award 2009.

It is available in white, black, yellow, grey or polished stainless steel.
