It seems appropriate to start off by quoting Niels Diffrient, the pioneer of modern ergonomics and creator of the Humanscale brand, which sets the highest standards in this field. “There is no perfect chair,” Niels Diffrient said. “A bed is the most comfortable chair. In a bed, the weight is distributed as evenly as possible, which removes the gravity-induced strain concentration in certain body segments.”. This introduction, though, is not in the least intended to urge you to grab your laptop, crawl into bed, and start working from there. In principle, it is best to keep one’s bed a workfree area, while the other two positions, i.e., sitting and standing, should be reserved for work activities. What is most important for the sitting position is finding the best possible chair.
The Importance of Intuitiveness
The IQ chair has achieved this aim as much as possible. From a structural point of view, the surface curvatures ensure a high degree of precision in enfolding the different body segments. The backrest has an S-shaped curvature matching the natural curves of the spine. Based on data that around 95 per cent of all people are reluctant to adjust the reclining mechanism because, among other things, it would lead also to distraction from their intellectual work, the intelligent chair does not require such adjustment. The unique recline system is designed in such a way as to respond to the sitter’s individual weight and individual movement patterns. This way, leaning back relieves 30 to 35 per cent of the strain concentration without you having to think about it. The headrest, matching perfectly the spinal curvature in this zone, automatically repositions itself and meets the head in such a way as to maintain the visual level, which is important when working with display screen equipment. The IQ chair features alternative armrests. They are attached not to the seat but to the backrest. This way, they follow the torso movement just as the arms follow the body movements, thus relieving some 20 per cent of the strain concentration. Other advantages of the intelligent chair’s ergonomic design include the system coordinating the parallel height of both armrests, the possibility to lock them in a certain position and to set such position precisely so as to ensure comfort while typing on a keyboard. Additionally, the materials used build on the ergonomic design of the IQ chair’s geometry. The upholstery is comprised of a padding, soft foam and a gentle gel layer, which reacts to the sitter’s weight and prevents its concentration onto certain points. The armrest upholstery is comprised of a special innovative material that softens the elbow touch. The purpose, once again, is to avoid stress.
