We have a 2006 Sundancer 260...maybe seating is similar. I was at a loss as to how to get one of the seats off. IA canvas guy showed me that the bottom part lifts off...but hard ..because a very heavy duty velcro holds it down. Once the bottom part of the seat is up then the top part has screws toward the bottom to remove that part. you kind of need to push up the bottom ,aterial a little to see the screws. When I got my seat off it was filthy under them. Probably never have been taken apart before. When he was pulling the bottom of the srat up it sounded like something was tearing. I would have never kept going if I had heard that noise, but he obviously has done this before. Let me know if it works for you.
