The Plopp family of stools by Zieta Prozessdesign was first shown on the exhibition of Young Creative Polish Designers in September 2009. The new Plopp Family includes: Mini Stool, Standard Stool and Kitchen Stool.
Although the stools look like blown-up plastic, they are made of steel. Plopps are produced using an innovative technology called FIDU. According to Zieta, FIDU stands for FreieInnenDruckUmformung — the Internal Pressure Forming — which implies inflating two steel sheets welded around their edges into a 3D object. It takes only two thin steel sheets to create a complicated and very durable 3D object from steel in FIDU.
FIDU allows to create innovative, customized, bionic shapes and fully recyclable objects using very efficient mass production processes and individualized shaping methods. The technology can be applied to form new design shapes but also as an ultra-light construction of great weight-capacity for design and architectural elements. FIDU enables mass production of individualized shapes. Forms made in FIDU are very light but also very durable.
