interstuhl | MESH DESIGN BLACK

The PUREIS3 concept 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 PUREIS3 that had this function and purpose. Together with engineer Joachim Brüske, b4K founder Andreas Krob collaborated with Interstuhl to develop the brandnew Smart Spring technology of the PUREIS3 with 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.

- Black plastic (standard).
- White plastic (option).

- Smart Spring technology - Different people can use the chair without having to adjust the settings to their weight each time. The adaptation of the reaction force is controlled purely by the smart materials.

- Seat height setting, infinitely variable from 420 to 520 mm. Self-supporting safety gas spring.
Backrest:
- Upholstered mesh backrest (Chillback, 12 mm).
Armrest:
- T-armrest, rigid, same colour as plastic, 3D T-armrest, adjustable height/width/depth, soft (same colour as plastic). 

Castors:
- Hard double castors, black, load-dependent braked, for soft floorings (In accordance with DIN EN 12529).
 

     “Active sitting” means regular, balanced movement; the innovative S 4.0 sensor solution provides the digital stimulus. The application, which was developed in collaboration with Garmin, analyses the user’s individual sitting habits and actively helps them to improve the way they sit. The sensor can be fitted to the PUREIS3 using a small holder, and demonstrates the highly innovative nature of the chair: the Smart Spring and Smart Seat automatically ensure that sitting habits are active and healthy. They are complemented by the application’s prompts to change posture and its instructions for office workouts.
