The spine is composed of 33 vertebrae, intervertebral discs, muscles and ligaments. Intervertebral discs play a crucial role as support points for movement and shock absorbers for the vertebrae. When you jump, when you have poor posture... or simply when you sit, your intervertebral discs compress to protect your vertebrae by absorbing the shock or excess pressure.
The intervertebral disc is composed of an outer fibrous ring and a gelatinous nucleus. This nucleus, made of more than 90% water, generates internal hydraulic pressure. This hydraulic pressure varies depending on the positioning of the vertebrae, thus on the position adopted and movements performed. Throughout the day, depending on your position, this hydraulic pressure empties the nucleus of its water, which reduces its shock-absorbing capacity.


Fortunately, the nucleus recharges with water thanks to the presence of hydrophilic cells (attracting water) that rehydrate it when pressure decreases in lying position at night.
Prolonged non-dynamic sitting position has negative effects on posture. It can cause skeletal and muscular disorders but also increases the risk of many health problems such as:
Studies show that if, in standing position, the pressure between the 3rd and 4th lumbar vertebrae corresponds to an index of 100, the pressure can rise to an index of 200 in poor sitting position. And each day spent in sitting position reproduces the same constraints which in the long run can have a negative impact on your health.
The dynamic sitting provided by the NOA cushion stimulates the erector muscles of the spine, which reduces pressure on intervertebral discs. It thus allows them to ensure their shock-absorbing role longer. It also allows better vascularization of this entire body area. It therefore promotes oxygen transport in the blood, essential for proper functioning of back muscles. This better vascularization also nourishes the intervertebral discs. Moreover, adopting dynamic sitting with the NOA cushion will help you become aware of your back position. It will allow you to regain a healthy sitting position respecting the three morphological curves of the back and neck.

Beyond that, the dynamic sitting provided by the NOA cushion prevents the body from entering lethargy. Maintaining correct posture while sitting requires a certain effort that we are unable to maintain over time. We must constantly reposition ourselves to avoid a position that becomes harmful to our health. In sitting position, the spine no longer has its three natural curves, the pelvis spontaneously tilts backward, the discs are pinched forward, the nucleus slides backward, the viscera and vessels are compressed. Even if they seem minimal, the cushion allows maintenance and compensation exercises through the movements it generates. These imperceptible movements force your muscles to work during all hours spent sitting. In doing so, the cushion will strengthen, among other things, your back muscles, an effective way to prevent back pain and improve organ function. Your overall health will be improved.
