Plane sleeper shelf with tray table support

Here is my first of many public domain ideas, this idea came from riding on long trips on a MD80 plane, I would pull the magazines about half way out of the seat holder and bend them down so I could rest my forehead and get some needed rest during the flight, This thing is very alpha and I would like some help improving the design,function and safety all I ask is to tag the thing with GridWorks 2018, I have included the very first test part that has been flight tested this thing has the unintentional hole that came in handy holding the cloth for comfort, this part was a failed print due to a Windows 10 update/reboot but the thing worked OK during a real MD80 flight and about two hours of rest. The support stand is for the tray table and never been printed or tested, think it might need a foot strip or tie straps to be safe. Tray stand is needed for newer planes.
