Section 407 is part of the Outdoor Club area at Lambeau Field. Unlike most of the stadium, there are individual seats with chairbacks instead of the normal bleacher seating found in the stadium. The seats are wider than normal stadium seats to make them more comfortable for club ticketholders but this does not mean that all fans will be able to fit into them. If the seat is not wide enough, you also have access to a club lounge, so you can go in there and find a place to sit. With these tickets, you should be able to find a place that accommodates a larger person either in your own seats or in the club lounge.
