Multiple different versions. In deactivated mode it reduces to the size of a match-box. The basic version has nine settings, based on seating requirement. So for example, if you want an office for two people, simply set the dial to two before activation. This version comes with an overhead extendable ramp for a small warthog, dog or cat, inbuilt electric chargers, seat-warmers and snintercom capability. Picture here is the basic version on setting one.
