In a saddle seat your spine stays aligned naturally without a backrest. This occurs for two reasons: First, the open thigh-to-torso angle naturally aligns the spine, and second, the wide spread of the knees (called hip abduction) automatically holds your pelvis upright.

It has been both scientifically proven and experimentally shown that dental work is ergonomically challenging. Yet, the ergonomics can be at high level, if attention is paid on the environment and how the environment is used.

If you sit in a troublesome posture for the usual dozen hours a day and use digital devices, a few minutes of exercise cannot cure or prevent back pains and headaches.

The main cause of problems is that the usual poor posture stretches the ligaments between the vertebrae of the spine over time, and the vertebrae start to degenerate due to the continuous roundness of the back and neck. It is caused by the thighs that are in the front of the body. This tilts the pelvis backwards and the posture becomes round. Muscle tensions follow. On a traditional chair the situation is hopeless.

The important principle “use it or lose it” also applies to joint health.

Joints need regular and moderate exercise because only that effectively “lubricates” the joints, activates cell renewal, and strengthens muscles around the joints. We also need exercise and stretching that maintains the wide movement range of the joints.
