Description
Armrest
Armrests help to relax the shoulder and neck area. The armrest generally depends on the length of your upper arm. If your upper and lower arms form a 90° angle, then your armrests are correctly adjusted. It is important that your elbows always rest on the armrests, as this is the only way to ensure that your body area relaxes. To set the optimal armrest height, the armrests should be height-adjustable. If you have a choice, you should opt for soft rather than hard armrests, because they are more comfortable and do not leave pressure marks on your forearms.
Backrest
It is important that the backrest is height-adjustable, because the top edge of the backrest should reach up to the shoulder blades. In addition, the backrest should be high enough so that the top edge is at least 45 centimeters above the seat.
Lumbar support
A lumbar support is an ergonomic back support. The lordosis is the lower part of the spine that is bent forward. The human spine is divided into five sections: Cervical spine, thoracic spine, lumbar spine, sacrum and coccyx. To ensure a healthy sitting posture, the lumbar support relieves the lower back. Therefore, the lumbar support should ideally be adjustable in height as well as in curvature. This support is especially important for people who already suffer from back pain.
Chair mechanics
The rocking mechanism of a chair is designed to relieve the back muscles. Depending on the model, a gaming chair has the possibility to adjust the backrest very far backwards (up to 180 degrees). The tilting mechanism is a very ergonomic feature that significantly helps to reduce back pain. This is because it relieves the intervertebral discs if you are not constantly in a monotonous posture or sitting position. The mechanism should be adapted to the user’s weight, i.e. the resistance of the backrest should be adjusted so that only minimal force is applied when leaning back. A normal or even ergonomic office chair rarely has this built-in adjustment.
