Last weekend, my wife and I had some friends over.  After the party ended, we decided that we wanted to watch a movie.  I decided to run to the Redbox booth to get a new movie that was out.  I got my keys and went to the booth.  I paid with my card for the movie that we wanted.  I drove back to our house and I got the DVD out of the case.  I own a PS4, so I placed the DVD right into the machine without opening the console.  I had to get the controller out of a drawer to play, but I found it easy to find out where to start the movie.  We all relaxed on the couch and ate some candy while we watched the movie.  We laughed at the funny parts and stayed awake for the whole movie, even when it got a little boring. 
Question: What were they sitting on to watch the movie?
A:
The all sat on the couch.
