Lumbar support: Studies show that properly adjusted lumbar support can reduce the risk of developing lumbar spine pain by 60%. Adjustable headrest: Neck support is key to preventing muscle tension and headaches. Ergonomic headrests, which can be adjusted to your height and position, contribute to the correct positioning of the head and neck. This is especially important, because studies show that an incorrectly positioned head can increase the load on the cervical spine by up to 30%. Adjustable Armrests: Armrests that can be adjusted in height and position help reduce stress on your shoulders and arms. It is important that the hands are in the right position while working, as this can reduce the risk of tunnel syndrome by 40%. Evidence Base Scientific studies confirm that the use of ergonomic chairs significantly improves the posture and general well-being of users. In particular, a study conducted at the University of Washington found that workers who use ergonomic chairs experience 25% less back and neck pain than those who use standard office chairs.
