We got the replacement couch, along with a matching barrel chair, for our Sunseeker at rv seating
I think ours is the Monaco, but don't quite remember. They were in the Los Angeles area, a nine-hour drive from us, so we went to look at their stock. At the time we went they had none of our desired model in their showroom, so they took one off the loading dock for us to look at and try out.
The only thing I had doubts about was that all their furniture has what I call a "wrinkly" finish, something I'm not a big fan of. My doubts vanished when they said, "Sure, we'll make it without wrinkles."
Be very careful of your measurements. We measured the space in our unit and had to wedge them in. They overhang our slide platform so we had to take them out to extend the platform with 3/4-inch plywood so they wouldn't rock forward.
Ours is made of two end sections and a center, which connect together with pins. This, along with the detachable back allows the couch to be installed in pieces. I think there are slots for the seat belts to come through, if you need them.
The company calls them "wall-huggers," but we still had to mount them about five inches from the wall so the backs wouldn't hit anything when reclined.
We got the electric recliner option, and the little tray tables. The tray tables are stored in a bin in the center section. The recliners take 110V power but have a pair of 9V backup batteries inside each brick. 9V batteries are notoriously gutless as far as power output goes, so I'm thinking of getting a 12-to-18-volt converter to power the motors in the absence of shore power.
The barrel chair (we call it the "jump seat" because it's right behind the cockpit) was a bolt-in replacement for the old one.
