An arm support is suitable for workstations where forearms lack desktop support, but it is not equipment for fixing the body. Desk conditions, chair height, and keyboard distance still need to be adjusted first.
First, identify the cause of unsupported arms
If the chair is too low, the desk is too high, or the keyboard is placed too far away, adjust existing equipment first; an arm support can only supplement the contact surface.
Multi-joint models focus on movement trajectory
Rotation and height adjustments help follow mouse movements, but ensure they don't hit armrests, drawers, or aisles.
Aluminum alloy models focus on fixed positions
A more rigid structure still requires suitable desk edges and stable clamps, and the contact point should support the forearm, not press on the wrist.
The desk surface is the most important installation condition
Solid, flat edges are easier to secure; glass, hollow, slanted, or rounded desk surfaces should not be clamped without evaluation.
- Desk thickness
- Clamp contact surface
- Left and right range of motion
If numbness, persistent pain, or localized pressure occurs after use, discontinue use and seek qualified professional advice.
