There aren't many options to work with in trying to fit 4 seats inside 9'. You have to go with 2 or more armless seats to hit the narrow width you need. If you consider Bass Industries, their Deco Penthouse, Olympia, Penthouse, and Majestic would be close if you did a center loveseat in a straight row. It would total 109". Depending on what you are willing to consider, you could create a four seat sofa (no arms except the one on the far right and far left) in a |0000| configuration. Then there are a lot of brands/styles that will work.
