The aeris Motion Concept: Move, Naturally.

Not all movement is healthy. Monotonous movements, abrupt movements, too much movement and unnatural movements can stress the body.

That’s why the 3Dee-Active-Office-Chair motion concept was developed with health experts, chiropractors, and doctors.

The 3Dee concept is different. It’s patented, it works…..and it feels good!

Setting options

  • Seat height
  • Weight (spring soft/harness)
  • Flexible sideways movement
  • Backrest tension
  • Lumbar Support



The 3Dee is the result of absolute consistency: in engineering as well as in design.

It makes for a sustainable change of office life: More well-being, higher energy, better balance. With 180 patents, such as the patented 3D technology, sets 3Dee apart from regular ergonomic office chairs. It supports and encourages movements to the side, forward, backward and even vertical swinging. In addition, the comfortable, semi-high back comes with individually adjustable lumbar support - ideal for conscious relaxation in between. With it's sleek design, the 3Dee chair is as appealing to look at as it is comfortable to sit on.

Height adjustment:

With the lever under the seat you can adjust the height. The open angle of the legs should be slightly above 90° and we recommend that the height of the desk be adjusted where possible.

Spring tension:

You can adjust the extent of vertical movement to suit your weight and personal preference. The optimum setting is when you can move freely up and down without resting on the bottom stop. For adjusting the spring hardness we recommend care - fully turning over the seat and leaning it on the backrest.

Adjustment: Screw the sleeve on the spring strut to the left – for maximum vertical movement/low weight. Screw the sleeve to the right (observe STOP mark!) – for reduced vertical movement/more weight.

Backrest Tension:

Use the butterfly nut under the seat to adjust the tension of the backrest. Turn the butterfly nut to the left in the’ –‘ direction (about 10 –15 times) for a softer setting with less tension. Turn the butterfly nut to the right in the ‘+’ direction (about 10 – 15 times) for a harder setting with more tension.

Lateral flexibility:

We recommend starting off with a setting for reduced sideways movement and later adjusting the setting to provide as much sitting movement as possible.

Adjustment:  Carefully turn over the 3Dee and lay it on the backrest. Turn the handwheel to the left for more sideways movement and to the right for less sideways movement.

Lumbar support:

Using the lever on the inside of the backrest bar on the right, you can continually adjust the curve of the lumbar support to suit your physique and personal preference.

Adjustment: Sit on the chair without resting against the backrest and grasp the adjusting bar of the backrest left and right with both hands. Press the lever on the inside on the right, and move the adjusting bar up or down into the required position.

Cleaning & care instructions. http://www.aeris.de/en/service/care-instructions/ 

  • Always dab off stains immediately using plain kitchen paper, for example, before they seep into the fabric.
  • Use lukewarm water and pH neutral soapsuds for optimum stain removal.
  • Stains containing oil and fat should be treated beforehand with ethyl alcohol applied with a lint-free sponge or cloth
  • Rinse with clear water after each cleaning treatment. Never use chlorinated detergents.
  • Only dampen the seat and never make it completely wet, otherwise the cushioning under the fabric might be damaged. Therefore use only very small amounts of water and detergent.
  • Avoid marks by cleaning from the edge of the seat to the middle.

Warning: Benzine, acetone and the like might dissolve the foam material under the cover.
