On our Tradewinds, the sofa is not "bolted" in, rather it is held by three screws into bracing on the wall behind the sofa. These screws are accessed by opening the sofa part way and reaching down through the opening with a cordless drill and bit. Check to make sure yours is bolted through the floor. As on your coach our recliner was bolted through the floor as it has a plate and turn table mechanism to secure.
