Comment

Overall, the employee feels that the changes made to her workstation have made a substantial difference in her physical comfort level. In particular, in the follow-up survey, the new articulating keyboard tray was rated as "very comfortable"* and the mouse was rated as "comfortable"*. Also, viewing images on the computer screen was rated as "comfortable"* because the employee no longer has to wear her glasses to see her computer screen.
