Toan Nguyen designed the playful, modern stool that is part of the Walter Knoll Bellows collection. Innovative design and new ideas are the best. Bellows is a clear example of this. The collection was awarded the Red Dot Award for Product Design in 2010 and the Iconic Awards for Innovative Interiors in 2011. The height of the Bellows Collection can be easily adjusted by means of a trigger within the stool. The range consists of a stool and an occasional table. The leather is impressively gathered around the shapes. The height can be adjusted by means of a ring-shaped button that turns in the seat. Mixing the two pieces of the collection together creates a striking and unified look. Bellows is also suitable as a stand-alone piece. Regardless of its placement, Bellows is a unique addition to any home.
