SISTERS – FOUR ELEMENTS WITH A BEAUTIFUL RELATION. SISTERS is a unique collection of sculptural and versatile poufs and sitting units. They are designed without a particular "direction" and can be placed freely in the surrounding environment, which gives the interior designer unlimited creative ways to play. The design is soft, light and organic and comes in 4 sizes that can be combined or used alone. The largest size has a comfortable backrest, which makes it perfect for installations in large waiting areas and public spaces.
