Why the new range of office chairs is so special
Experience the Highlights of the PUREis3
With the PURE, sitting is freedom. It not only allows movement in all directions, but also ensures that the sitter is constantly in motion.
Forget everything you've ever known about chairs: PURE guarantees a sitting experience like no other – for the working world of tomorrow that is already part of our lives today.

MOVEMENT IS KEY
The purpose of the PURE is to enable as much of this required daily exercise as possible to be carried out while seated. PURE ensures active and dynamic sitting at all times.
INTUITIVE OPERATION
The PURE completely takes care of optimal seat adjustment all by itself. Its responsive material actively adapts to the user, to their weight, size, proportions and movements. This is made possible by an innovative combination of polyamide and glass fibres. Only the seat height needs adjusting. Additionally, the 3D movement radius can be temporarily restricted for focussed work. PURE - Ready. Sit. Go!
FOR ANYONE LOOKING FOR FLEXIBLE SOLUTIONS
Office spaces are becoming increasingly multifunctional areas. The PURE is as flexible as everyday working life. A team meeting, followed by meetings with customers, then focussed desk work? PURE is the right solution in every situation. Its intelligent design makes it a flexible partner in the modern working world, thanks to its ability to adjust to every user.

The office chair in practice
With the PUREis3, sitting is freedom
Forget everything you've ever known about chairs: PURE guarantees a sitting experience like no other – for the working world of tomorrow that is already part of our lives today.
Long periods of static sitting can be hugely detrimental to your health. Research, however, – studies conducted by the Fraunhofer IAO and the University of Tübingen in particular – suggests that just two hours of moderate physical activity per day are enough to offset the negative effects of a sedentary lifestyle. For many years, Interstuhl has collaborated with the Fraunhofer IAO to turn scientific findings into practical solutions.
Three factors with health benefits
PURE effectively promotes the health of the user in three ways:
Activation - PURE ensures that sitting is never static. Frequent posture changes keep muscles active, and legs, hips and spine are mobilised too.
Freedom - PURE guarantees that the user is never forced into an uncomfortable posture. This prevents blockages in the blood flow and encourages circulation. At the same time, PURE does not hinder the user when they have the urge to move.
Comfort - PURE guarantees constant and firm support in all movements. And because the ergonomics of a chair can only work properly if it is correctly adjusted, PUREis3 does this for you – completely automatically.
It is not the chair that promotes health but the movement it provides. PURE does everything to ensure that the user is relieved of strain and stays active.

Complete mobility
The amount of mobility possible with the PURE was researched in a biomechanical study conducted by the ETH University of Science and Technology in Zurich. The study showed that PURE offers new levels of material flexibility in the upper backrest of up to 22 degrees to each side, an opening angle of up to 38 degrees in the backrest, and a lateral range of movement of up to 26 degrees on the seat. The Smart Seat can also follow forward movements of up to 12 degrees.
Innovative
The Smart Spring technology
The core component – the "Smart Spring" – is made using a special polyamide/glass fibre compound. It enables the PURE to dynamically adjust to the user's body, weight and movement. The Smart Spring not only defines the visual appearance of the PURE; it also supports the whole chair and allows for impressive movement radii – including in directions that are impossible on other chairs. With no further need for adjustment, this enables true three-dimensional sitting.
Not all plastics are created equal. Interstuhl uses materials that possess high flexibility. Due to this, the plastic elements keep people moving even while they are sitting down. The plastics used boast high-grade surfaces, durability and are colour-fast and non-fading. Depending on the product, different colours can also be selected for frames, bases and seat shells, for example. This further increases the variability in the product design.
The upholstery in our products is made of foam manufactured at our foaming facility and has a particularly high density. In this way, we can ensure that it remains comfortable for years to come. Depending on the product, you can choose between a wide range of different covers, such as fabrics, synthetic leather and real leather in different colours. The materials differ in terms of their characteristics, such as the look and feel, yet all of them meet the high demands on quality and durability, and they pose no risk to health or the environment.
MATERIALS AND COLOURS
HIGH QUALITY AND VARIETY
PURE fits perfectly into any environment. Its clean-cut design and the large choice of colours and materials leave you free to customise your chair. The collection offers four swivel chair models: a mesh or upholstered backrest in either white or black. A variety of materials and colours are available to choose from. The Smart Spring, chair column and optional armrests are available in either all-white or all-black for all models.

The PUREis3 designer
Andreas Krob & Joachim Brüske, b4k
The PURE 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 PURE that had this function and purpose. Together with engineer Joachim Brüske, b4K founder Andreas Krob collaborated with Interstuhl to develop the new, innovative Smart Spring technology of the PURE with its core component: the curved Smart Spring on the backrest of the chair.
Sustainability
We take responsibility
Like all Interstuhl products, the PURE is consistently designed for sustainability. That doesn't just include a long service life – the ability to return products after use also plays an important role. After all, 98 % of the materials can be reused after the office chair has reached the end of its useful life. In addition, the PURE has received many environmental seals and certificates.
