I would have confidence in the old mounting method_ IF, the loveseat did not have to be moved out for the full-recline position. If it does have to be moved way from the wall to fully recline, I would install an "eye" screw in the floor at each end and use a simple polyester strap like the one used to secure reclining chairs that do require moving in order to use them.
