A health report by the DAK (status: 2018) shows that 77 percent of those surveyed suffer from complaints in the lumbar spine - i.e. in the lower back. These are often due to staying in an unhealthy posture for too long, i.e. static sitting. Added to this is the job-related lack of exercise that goes hand in hand with millions of jobs. In order to relieve the intervertebral discs in everyday life and prevent long-term postural damage, a healthy sitting posture is more important than ever. This can be supported by a functional wedge seat cushion: The sloping base ensures that you automatically assume an upright position when sitting and relieve your spine.
A wedge cushion on the chair tilts your pelvis, stretches the lumbar spine and relieves the intervertebral discs and muscles in the thighs and hips. For this reason, the upholstered underlay is particularly suitable for people who have to do their work sitting down - and therefore often suffer from chronic or acute back problems. In other words, the slanted seat cushion should always be used if you already suffer from pain in the lumbar area or want to strengthen your back muscles to prevent possible postural damage.
