This unique way of sitting encompasses four stages of movement; forwards, backwards, and side to side. Known as Joystick, the chair moves in each of the four directions to aid the user to reach for objects without having to strain or overstretch. The backwards motion enables the user to relax, with the forward tipping movement straightening the pelvis and the spine, thereby improving posture through the targeting of core muscles. This motion is beneficial, particularly when sitting at a desk.
