I am continuing with another modification. The arms of the jack-knife coach pull up & out for more room when sleeping. I had the idea of adding height to one arm so we could turn sideways and have an arm to lean against to watch tv comfortably. I have removed the bracket with the stud that inserts into the couch. And, have removed the staples holding the upholstery. I will be ripping 4, 30" long, 2" x 4"s down to 3" wide. Then, gluing and screwing them together to make a 6" higher arm. Then, having it upholstered in a matching/complimentary material. I'll ad some pictures tomorrow when I have the 2x4's done.
