keep in mind, the seat backs need to be folded down, but not folded up. You just pull the handle toward you and they will roll on out. think of it as a suitcase laying down, not standing up. I didnt read the owners manual the first time and it took me a few minutes to figure it out. i had them folded upright trying to release every lever in there and nothing happened. Yes they are heavy. of course mine is a yukon XL but i think they should roll out the same.
