It is a common belief that you cannot, or must not, sit on a saddle chair for more than a couple of hours a day. This is not the case for two-part Salli Saddle Chairs, on them you can sit happily and safely the whole working day. The position is physiologically better than on a traditional chair, because the weight of the body is divided between the sitting bones and feet.
On a one-part saddle chair, however, part of the sitting pressure is on the genital area. Nerves get pressed, and to escape the uncomfortable feeling the sitter will lean backwards, away from the pressing front of the chair. For men it is almost impossible to maintain the good position, because the pubic bone is pressing the testicles against the front of the chair. Even if the back is forced into the right position by a back rest, the pressure will still be on the genital area. Because of the uncomfortable feeling one rounds the back into the wrong position – it is because of this harmful sitting position that you should not sit on a one-part saddle chair the whole day.
The gap in the middle of the two-part Salli seat guarantees pressureless sitting, even when you are sitting for longer periods of time. This enables you to keep the back in a good position. Most of the weight of the upper body is on the sitting bones, which keeps the pelvis in a neutral position, leaning slightly forward. This position keeps the natural curve of the lower back, the position is the same as when we are standing. There is no need for a back rest, because a minimum muscular effort is needed to maintain the position. Circulation to the feet flows freely, and the vertebrae are not pressing the disks.
The two-part seat is also cooler and makes you sweat less. This makes it also healthier because the lower temperature reduces the risk of genital infections.
Even on the two-part chair it is vitally important to change position and have breaks – reach and bend, exercise and stand for a while. The more you move during the day the better. On the active Swing and SwingFit seats it is easy to get movement in the back also while sitting.
