3Dee chairs can swivel, of course, and tilt forwards or backwards, or let one gently bounce up and down on its large spring, or even enable reaching from side to side -- all while still keeping the back erect, to relieve intervertebral discs, stimulate blood circulation, and supply oxygen throughout the body. And with a sleek design, and choice of colours, it can fit into a wide variety of office decors.
The microfiber seat for this active offer chair currently comes in either red or black, paired with either an all black frame or a black frame with some polished/shiny elements.
The Most Innovative Office Chair in the World
Activated: Your back keeps straight, because the 3Dee Active Office Chair follows your movements as you sit. Moreover, your back gets strengthened by frequent changes of posture, and that also helps keep your muscles fit.
Yet Relaxed: The backrest with patented lamellar technology [please see area 2 in the diagram below] and the physiologically-shaped backrest cushioning [area 3] provides support without restricting freedom of movement. The lumbar support  and backrest tension can each be individually adjusted.
Motivated: The patented 3D Technology in the unique movable ball-bearing joint in the base (below area  in the diagram) and the spring strut support and encourage harmonious 3 Dimensional movement and frequent change of sitting position, by enabling full flexibility of movement not only backwards and forwards but also up and down or to either side. This stimulates your circulation, strengthens core muscles, helps keep you fit, and is also fun!
It can also increase productivity, by facilitating freer, deeper breathing, which enhances concentration, and the combination of universal rollers for the whole chair and multi-directional repositioning for the seat itself can extend your reach and ensure an optimum sitting posture with respect to your working surface.
Unrestricted: The intelligent seat is slightly convex, upholstered with breathable multi-zone integral foam  and equipped with the flexzone technology  for a healthy seat climate and optimum sitting comfort without pressure points.

The aeris spring strut -- which is also found in the Swopper and Swoppster models -- is the central element of the highly complex 3D mechanism in the 3Dee which enables its unique vertical bouncing movement.
The specially developed flexible seat plate with multi-zone foam adapts to each sitter's physique and thus avoids pressure points and deters bad posture habits (like sitting on the edge).
3D Movable Joint
This is where the vertical bounce meets an innovative high-tech joint that is responsible for the sideways movement as well as the backwards and forwards movement. You can adjust the flexibility of movement individually -- for more or less exercising of your muscles, as desired.
Adjustable Lumbar Support
The completely new, lamella-based backrest of the 3Dee office chair is an ergonomic highlight. The lumbar support can be adjusted flexibly to match any user's physique.
Special high-tech cushioning with new, climate-active cover for feather-soft sitting comfort. Five perfectly matching functional layers provide breathable, pressure-relieving and heat-regulating sitting.
The aeris motion concept: move, naturally.
