My boat is a 2007. I’m having trouble removing the port side “lounge” seat bottom cushion. it’s across from the helm station and has an aft facing seat back. I can’t figure out how it’s attached?. It’s directly over the cabin passageway to the aft sleeping compartment. The passageway has a headliner so I can’t tell if the cushion is through bolted without removing the headliner. I’m concerned about messing up that headliner. Does anyone know how this cushion is attached? I need to have the cushion recovered. Are there “clips” which can be triggered to release? Thanks anyone for taking the time to try and help.
