Seats are a pretty big safety item. What works in a truck cab may not be ideal for a sedan. The seat is our first line of defense in a collision, if the seat gives out then nothing else is going to hold you in position. I had a friend loose his life in a low speed collision because the seat back gave out allowing him to fall back into the rear area of his rod. He sustained a head injury that killed him on the spot. It was an accident that he should have walked away from, but the boat seats he was using weren't designed to hold a 240 lb man up when struck from behind at about 15mph. They were designed to hold you up while fishing on a pontoon boat.
