IKEA desk chair (Langfjall)

Height-adjustable seat allows you to adjust the height so that back and legs are at a 90° angle. The lumbar support helps maintain the correct posture while sitting which reduces strain on muscles on your lower back. Increased stability since the tilt function is lockable when the backrest is in the upright position. You can lean back with perfect balance, as the tilt tension mechanism is easy to adjust with an Allen key to suit your weight and movements. Armrests provide support for the upper part of your forearms and reduce strain on the back and shoulders during long meetings. The safety casters have a pressure-sensitive brake mechanism that keeps the chair in place when you stand up, and releases automatically when you sit down.
