Sitting for long periods of time is part of our everyday lives - in the office, in the car or on the sofa. But too much sitting makes us sluggish: Muscles slacken, the spine becomes unstable and tension increases. Studies show that a lack of exercise endangers health. Even small changes such as dynamic sitting or short breaks in movement make a big difference. The ergonomic SISSEL products promote more activity when sitting - for a healthy posture and greater well-being in everyday life.
