What makes the PUREIS3 so extraordinary? Its boldness to focus on what's most important. Its design is defined by one core component: The Smart Spring. It cuts a striking curve from the backrest down to the chair column. The transparent membranes in the backrest showcase the inner workings of the chair. This gives the PUREIS3 an appearance that is defined by lightness and ease. The design of the chair column is just as clean-cut: The Smart Spring and chair column are available in either all-white or all-black. Thanks to the harmony in its colour scheme, the PUREIS3 blends into every space perfectly. A variety of mesh colours and a wide selection of upholstery materials and colours are available for an individual look. PUREIS3 impresses with its functional design. It makes a visual statement: Modern, clean-cut, functional.

Design: Andreas Krob
and Joachim Brüske, b4k

The PUREIS3concept is based on the requirements of the chair's user in their daily life at work. But what makes a good office chair nowadays? It should be intuitive to use, adapt to its user and enable active, dynamic (i.e. healthier) sitting. Working on this basis, the Swiss design agency b4K set to work to devise a PUREIS3that had this function and purpose. Together with engineer Joachim Brüske, b4K founder Andreas Krob collaborated with Interstuhl to develop the brand new Smart Spring technology of the PUREIS3with its core component: The curved Smart Spring on the backrest of the chair. Thanks to its innovative materials, the technology enables optimum, tailor- made sitting comfort and active sitting in all directions, meaning a traditional chair mechanism is no longer required. The product designers deliberately opted for a much reduced, clean-cut design for the PUREIS3. This makes the PUREIS3 unmistakeable and aesthetic, but not overbearing, in any space. The single colour of the Smart Spring and chair column highlights the clean-cut design, while the absence of a mechanism makes the chair visually and physically light and flexible.
