- Arm support is only at the wrist
- Does not allow relief for the weight of the arm
- Greater reach distance to the work surface
Relaxed arm support causes pressure at the wrist only
This small resting area does not allow relief for the weight of the arm
Over time the upper torso can collapse forward with forward tasks
With mixed tasks on the work surface there is greater shoulder reach distance to get beyond the keyboard to get to the work surface
The combined lack of support and increased reach distances to the can easily cause slumping with forward tasks.
