· Circulation is undisturbed when we sit on a two-part saddle chair. Bones (sitting bones, feet and elbows) carry the weight, so there is no pressure on soft tissues. The posture is the most relaxed and natural, when the legs are apart and sloping down in a 45 degree angle, which makes the pelvis automatically tilt forward. When the pelvis is tilted forward the back is in its neutral position. It feels easy and natural to sit when one is balanced in the same way as when standing. No muscle tensions or outside pressure disturb circulation. Deeper breathing and improved circulation enable the body to get enough oxygen and nutrients.
