Mini side table plans

Hi all,
While we were camping at Fort Clinch with the other Florida Tearjerkers a thought came to me about making mini side tables to put a glass, cup of coffee or something on while we're sitting on the couch.
Here's a basic idea I've come up with. Tell me if you think it will work. I'm picturing using 1/4" or 3/8" wood. In my plans I wrote a piano hinge, I know that won't work because the table won't be flush against the wall.
Anyway, I'm open to any ideas and input you might have.
Thanks,
Lynn
