The common factor among all of the above is immobility. The body remains in the same position for hours, and the intervertebral discs are under constant pressure at the same points. <\/p>\n\n
How Sitting Strains the Spine<\/h2>\n\n
Medical research shows that sitting increases pressure on the intervertebral discs by as much as 40% compared to standing. With a hunched or poor posture, this pressure can increase by as much as 90%. <\/p>\n\n
The problem lies in static sitting\u2014that is, sitting in which the body remains in the same position the entire time. In this case, the pressure isn\u2019t distributed along the spine but is always concentrated on the same segments. That\u2019s exactly why the following symptoms are most common when working from home: a dull ache in the lower back, tension between the shoulder blades, and a stiff neck. <\/p>\n\n
The solution isn’t to look for an even softer or more expensive chair. The solution is to find a chair that encourages the body to move\u2014even while sitting. <\/p>\n\n
Active Sitting: The SpinaliS Solution<\/h2>\n\n
The SpinaliS chair was designed with a single purpose in mind: to translate the proven benefits of sitting on a therapy ball into a form suitable for everyday computer work. The central element is a patented, spring-loaded, movable seat that follows every movement of the body while sitting, thus enabling continuous active sitting\u2014without the loss of support that a traditional therapy ball cannot provide. <\/p>\n\n
What this means in practice:<\/p>\n\n
- \n
- The muscles remain active.<\/strong> The deep stabilizing muscles of the spine constantly adjust slightly to the movement of the seat, rather than \u201cshutting down\u201d completely while sitting.<\/li>\n\n\n\n
- The pressure on the tiles is distributed.<\/strong> Because the seat moves slightly and continuously, pressure does not build up at a single point, which reduces the risk of long-term wear and tear.<\/li>\n\n\n\n
- Better blood circulation, less fatigue.<\/strong> Active sitting improves blood circulation, which means more oxygen for the brain and, as a result, less afternoon drowsiness\u2014this is especially important when working from home, without the breaks that a typical office environment naturally provides.<\/li>\n<\/ul>\n\n
During the first few days of transitioning to active sitting, it is perfectly normal to experience mild muscle fatigue. This is not a sign that something is wrong\u2014on the contrary, it is a sign that the muscles, which have been inactive for years, have finally begun to activate. <\/p>\n\n
Comparison: What are you actually sitting on when you work from home?<\/h2>\n\n
Before you decide on a new chair, it makes sense to ask yourself a simple question: What would you really like to sit on for 6\u20138 hours a day? The table below summarizes the pros and cons of the most common options. <\/p>\n\n
