I was looking for a Michigan-related gift for my stepdad for his birthday next month, and I came across this stadium seat that attaches to the top of the bleacher at Michigan Stadium. It's a pretty decent price so I may get one for myself also because after awhile those bleacher seats at The Big House hurt your ass big time. I was wondering if anyone knows if there's any restrictions on seat cusions like these? I don't recall ever seeing them but they're pretty nice and I'd love to take them to games. Thanks.
