I seriously considered the 1909S, but? For the same reason you are now skeptical, we went with the 2109S. The 2109S was about the same weight too, but the tv location is one of the best I've seen in any line. You can watch from the sofa or left bed position. She watches from bed, me on the sofa usually.
Also, the North South walkaround queen was ideally suited for us. Actually, it was a must. *LOL*
Slight edit while thinking. IF they can give you a swing arm that moves out to the door, the angle MAY work so both can see from the sofa. Just a thought.
