Works on wheelchairs with "desk" arms, too!
My husband recently had a stroke. The wheelchair he used in rehab had a half tray like this. It supports his arm and hand, allowing him to remove his arm sling. He was really thrilled when we opened the package. His therapists like it because it's better for him not to be in the sling overmuch, and they like that it is clear. My husband is 6 feet tall and somewhat overweight, and this tray does not cramp his sitting space. We would highly recommend it!
