These hydrologic chairs that shake and move to what is going on in the movie to submerse you. You can adjust the intensity and even disable them.
That is a seat that moves with the movie and has vibrations as well. You do a control on the right arm rest to control the seat in how much motion and vibration you receive from the movie.
D box is not really worth the extra money, just buy regular seat and buy the kid behind you a bag of popcorn and have them kick the back of your seat the whole movie it's about the same thing
It's basically a seat that shakes and moves with the movement and shakes of the movie if you have any kind of movement issues than to not choose this thing if you get car sick don't use it
