Flexible 3 D seat and default settings
Company Haider Bioswing from Pullenreuth (Upper Palatinate) has made a name for itself as a manufacturer of health care and therapy systems. As the name implies, all office chairs are equipped with a mobile, company-patented 3D® seat system that flexes with every movement. I tested three different models.
The back and armrests can of course be adjusted in height on all models, the seat height and depth as well as the seat inclination can be adjusted to support the tilt of the pool. This is to be used for the erection of the spine in its natural double S-shape. All chairs are covered with coarser or finer microfiber material, the resistance of which must only prove itself in the course of time.
450 iQ S
My first impression of the 450 iQ S is positive: I have never sat on such a comfortable chair. Ideal: You can fix the backrest at the desired angle or adjust so that it adapts to the body when leaning forward or backward - this function has called the manufacturer TrainBackMatic.
Yes, the chair even responds to the leaning pressure and automatically synchronizes seat and backrest, whether you are sitting or bending back. In addition, the backrest backrest pressure can be individually fixed. Thus, straight or comfortable sitting is possible in all variations.
A lumbar support in the back pad should relieve the lumbar spine by means of a stepless adjustment of the arch, but defacto is hardly noticeable. The round neck support, which can move further forward and upwards, but not backwards, I feel even as a little disturbing, but you can also take it completely.
However, the most outstanding feature of the chair is and remains the flexibility of the seat: The leads after prolonged sitting on smooth soreness, especially in the abdominal area. However, this luxury seat has a hefty price of 1560 Euro.
V260 iQ V
A flexible seat is also an outstanding feature of the V260 iQ V, which with 800 Euro is just half as expensive as the 450 iQ S. The price is also noticeable in seat comfort. Overall, the cheap chair has significantly fewer adjustment possibilities, but this does not necessarily have to be bad:
The backrest adjustment called VarioBackMatic also responds to the leaning pressure and adapts to any sitting posture, but less easily than the 450 iQ S.
When you sit straight, you almost get the impression that the backrest pushes you forward, for the lean back you have to spend more power than the 450 iQ S, which also trains the abdominal muscles.
The depth adjustment of the seat surface can provide relief here, but this is a lot softer than with the 450 iQ S, which ensures easy sinking.
Unfortunately, the lumbar shaping in the back pad to relieve the lumbar spine is only optional for an additional charge and not available for my test chair, although it would be particularly helpful because of the special backrest mechanism. There is also a quality difference in the rolls, which are made of plastic, in the other two models, the middle part is chrome.
An extravagentes model is the boogie saddle, which is priced at just 1032 Euro in the lower midfield in the three comparison models. Noticeable is the leather-like microfiber material that the chair is upholstered with, giving the chair a stylish look - as well as the saddle-shaped seat with the T-shaped backrest.
Overall, this chair has significantly less adjustment possibilities: the backrest can only be adjusted upwards or downwards, armrests are not available, instead the elbows can be placed on the backrest.
Instead of an adjustable seat, the chair automatically reacts to the center of gravity of the body from the front to the rear, thus permitting a permanent and body-synchronized adjustment of the seat and backrest inclination.
Because the most outstanding thing about this chair is the ergonomic, saddle-shaped seat, in which the legs are not "laid down" as usual in the front, but on the left and right. This automatically leads to a physiologically correct sitting position: The pelvis tilts forward and the spine can erect itself into its natural double S shape. This should be one-sided pressure on the discs are prevented. Comfort is provided by the short, but comfortable backrest.
Overall, therefore, a very back-friendly and quite comfortable sitting position, unfortunately the human factor gets in the way. After a short time, I miss the opportunity to lean back on the chair for a short while, as is the case with the other models. Instead, I cling with great stress in the back of the turnstile - not healthy again. It may be that the boogie saddle is the most innovative of the three test chairs - maybe it's just too innovative for me.
The human factor
The human factor is also the basic problem with all three chairs tested: upright, back-sitting is not very comfortable in the long run, it has to be trained. Otherwise you could spend a whole day sitting on a seatball.
At the same time, all three chairs do not solve the fundamental problem that prolonged sitting is unhealthy - even on bioswings you get back pain over time. Nevertheless, I find all three models better and healthier than previous seats I used. Nevertheless, it is also important to get up again and again, to do gymnastic exercises and to move.
