A forearm rest can reduce the load on your shoulders by supporting your forearms (not your wrists or elbows) when using the computer. Several ergonomic forearm rest styles are available online. Choose one that doesnt lock you into a single posture. If youre using the arm rests on your chair arm but are experiencing discomfort, try removing the arm rests. They can sometimes place your arms in an awkward position or put pressure on the nerves in your elbows. Make sure to support only your arm weight on the forearm rest, and not your full upper body weight.
