Lumbar support

What is a lumbar support?

A lumbar support is a part of the backrest of an office chair that takes into account the forward curvature of the lumbar region (lordosis). Spine forward in the lumbar region (lordosis), i.e. it is modelled on the human spine. It should adapt optimally to the user's back and body size.

When is a lumbar support useful?

Long, rigid, one-sided sitting, for example in the office or in the car, puts strain on the lumbar spine and leads, especially in the lower back, to the so-called hunchback and thus often to severe pain. MalpositionsThis often leads to severe pain, especially in the lower back. Sometimes the pain can also radiate from the lower back into the leg. In this case, we speak of pain along the sciatic nerve radiating from the lumbar spine into the leg (Lumboischialgia). A lumbar support is intended to support and relieve the lumbar region when sitting for long periods without movement, thereby preventing poor posture and pain. Since every back is different, the lumbar support should be individually adjustable, both in height and curvature. When adjusting the lumbar support, it is recommended to pay attention to subjective well-being. Thus, depending on the shape and subjective feeling, the support can be located in the inwardly curved area of the lower spine or somewhat lower, at the bony iliac crest. In any case, it must provide a comfortable, easily felt and upright support.

Is it possible to do without a lumbar support when sitting?

Yes, if you can behave according to your natural movement impulses when sitting. That is, if you can move spontaneously, intuitively, self-organised and thus as you do when walking and standing. After all, walking and standing are the natural movement patterns of human beings and no one uses a backrest or lumbar support when walking, for example. Strictly speaking, a backrest "incapacitates" a person's back muscles, which are actually designed to keep the back straight and thus the person upright when well trained. However, if the muscles cannot work because the rigid sitting posture or a backrest prevents them from doing so, a lumbar support has a relieving and supporting effect.
