The new dimension of sitting: 3D ergonomics

Conventional seats – even those that call themselves "ergonomic" – cannot do much against the daily lack of movement in the office. On the contrary: they can even contribute to muscular atrophy and bad sitting postures. aeris calls this the "sitting trap" – because there are often only a few years of working that lie between intensive use of conventional office furniture and the first signs of illness. aeris has completely reinvented sitting at the workplace.

With the unique concept of 3D Ergonomics we support and encourage the intuitive movements of the human being and lead the body back to adopting natural patterns of movement.


Natural movement in three dimensions.

The underlying concept of the aeris 3D Ergonomics is as simple as it is ingenious: the chair follows the movement of the body and not vice versa. The result: natural sitting, controlled movement up and down combined with posture-optimising movement sideways, backwards and forwards.

Vertical movement 

The vertical movement is the unique movement in the third dimension made possible by the sprung 3D technology from aeris. The vertical movement can be adjusted separately to suit each sitter's weight. This relieves the intervertebral discs, stimulates the blood circulation and thus ensures optimum supply of oxygen to all parts of the body.

Flexible sideways movement 

Harmonious 3D movements with a wide sideways reach increase the radius of action and optimise the natural posture at the same time. In addition, each change of position activates the blood circulation which in turn can increase the power of concentration.



The 3D joint located close to the ground provides for a natural forward tilt of the chair as soon as the sitter makes a move towards the desk. The result: your back keeps straight, you breathe deeply and your blood circulation is stimulated.

Innovation over convention.

aeris has set new benchmarks for office chairs with its innovative concept of 3D ergonomics. This is demonstrated clearly when compared with conventional sitting concepts. Whereas the 3D technology from aeris encourages active movement and thus enhances the sitter's health, many conventional office chairs lead to lack of movement and bad posture.

  Conventional ergonomics 3D-ergonomics by aeris  
Synchro mechanism As standard a mechanical element is used which permits linear and one-dimensional movement of the backrest and seat. The 3D mechanism enables intuitive, multidirectional 3D movement of the entire seat surface.  
Seat depth adjustment The seat with fixed front edge can be moved linearly backwards and forwards in ratchet steps. The seat with flexible front edge moves dynamically in all directions and adapts itself to each person's thigh length. In addition, the adjustable backrest lumbar support permits individual setting of the seat depth.  
Vertical movement No vertical movement, just a slight sinking of the gas spring. Full vertical movement (up to about 10 cm) with adjustable range of movement.  
Flexibility of sideways movement Mostly static.
Some with tilt mechanisms under the seat surface with slight flexibility. Maximum sideways tilt 2-3°.
3D movement element with pivotal point directly on the floor, which permits flexible sideways movement of up to 15°
Seat shape Straight or hollow seat surfaces with rigid seat edges which hinder upright sitting positions and might cause pressure points. Arched seat surfaces with flexible front edge, which support upright sitting positions and enhance the circulation of blood and prevent pressure points.  
Forward tilt No active forward tilt of the seat surface. A negative sitting tilt of max. 4° can be generated by of the synchro mechanism. The distance between the seat surface and the desk remains unchanged and leads to "sitting on the edge". Active forward tilt through a 3D movement element with pivotal point directly on the floor (up to 15° forward tilt). The distance between the seat surface and the desk changes individually (decreases) and thus prevents "hunchback posture" and "sitting on the edge".  
Armrests Available as standard or option. Purposely omitted, because armrests restrict natural movement. They are also not needed to help when standing up, because the spring of the seat does that "automatically".  
Backrest and lumbar support adjustment Standard, usually rigid or movable in one direction through a tilt mechanism. Height adjustment of the lumber support is usually possible. Backrests are supplied as standard (3Dee) and as option (swopper). With the 3Dee the lumbar support can be adjusted individually between 2.5 and 5.5cm. The flexible backrest mesh adapts to all back shapes.  
Operation Standard components with multiple adjustment settings, but without adjustment of the depth springing or sideways movement. Continuous adjustment for height, weight, sideways movement and partially also for the lumbar support and backrest counter-pressure.  

From the evolution point of view, we are simply no...

Sitting at work is a modern invention. Up to about 200 years ago sitting was a “matter of one’s standing”. Sedentary activities were primarily reserved only for persons of high standing like pharaohs, emperors and kings. The human being moved in the course of work, stood still or squatted. Only about 50 years ago did hours of sitting become part of daily life at work. A development that has taken our backs off guard. From the evolution point of view,we are simply not adapted to this.

Why this is so and how we can survive the modern world better and healthier is described on our pages
