It's not the body strength, it's the seat frame strength. Maybe you're not understanding what we mean by 'pass through'.Behind our armrest here on the Accords, there is a door for putting longer things through like skis. What people would 'ideally' like to have is that, with 60/40 AND armrest. The 1x2 ft hole in the seat is where structural integrity comes into play, there's not many ways you can give full support to the 60% seatback. That's the issue.
