I'm not sure on the swing. I can't figure out why else they have those 4 knobs on the bottom, with 2 inches of travel. Yet, when I tried to move one back more than the other, it was pretty tight and I didn't want to torque it. If you loosen them and just pull rearward, the whole back slides back easily. If you try to do it unevenly, the hinge points for the side bars are getting tight and libel to bend. So I'm not sure this one has swing. Hopefully someone who has another that definitely swings will speak up.
