Sitting reinvented

PUREIS3 is designed for sitting and made for movement. Unlike any other chair, PUREIS3 has been developed entirely with active people in mind. This approach has required a complete reinvention of the “office chair”. PUREIS3 adjusts to the user, their body and movements without requiring them to make time-consuming adjustments. Complicated and heavy mechanisms are no longer required. PUREIS3 not only allows a wide range of movement but also ensures that the user stays comfortable, active and sufficiently supported at all times. This is all made possible by an innovation that has never been seen before: Smart Spring technology. The core component – the “Smart Spring”– is made using a special polyamide/glass fibre compound. It enables the PUREIS3 to dynamically adjust to the user’s body, weight and movement. The Smart Spring not only defines the visual appearance of the PUREIS3; 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 – for anyone, anywhere. In addition, the PUREIS3 also boasts an innovative “Smart Seat”. This combines comfort, posture and complete threedimensional mobility.

Movement is the key

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. The purpose of the PUREIS3 is to enable as much of this required daily exercise as possible to be carried out while seated. PUREIS3 ensures active and dynamic sitting at all times.

Outstanding mobility

The amount of mobility possible with the PUREIS3 was researched in a biomechanical study conducted by the ETH University of Science and Technology in Zurich. The study showed that PUREIS3 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. These values are impressive, and PUREIS3 has been proven to keep its promise of maximum mobility for optimum health benefits. This makes PUREIS3 the lead product in Interstuhl’s active sitting solutions. But the most convincing way to experience PUREIS3 is by taking a seat yourself and enjoying a sitting experience like no other.

Three factors with health benefits

PUREIS3 effectively promotes the health of the user in three ways:

• Activation: PUREIS3 ensures that sitting is never static. Frequent posture changes keep muscles active, and legs, hips and spine are mobilised too.
• Freedom: PUREIS3 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, PUREIS3 does not hinder the user when they have the urge to move.
• Comfort: PUREIS3 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. PUREIS3 does everything to ensure that the user is relieved of strain and stays active.

Modern, clean-cut, functional

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
