It's like a 4d experience, just with out the shooting water.
Dbox seats are programmed to synchronize with the movie action on-screen and each seat is equipped with individual intensity controls. So if there is an earthquake (or similar action) in the movie the seats will shake and rumble etc. I've never used one but friends have told me they didn't like it and not worth the extra money. On that note I rarely see anyone sitting in the Dbox seats but maybe you'll like it.
