The 3X trailer deploys with the push of a button, tripling its interior space in a matter of seconds, turning a cramped road can by day into an expansive set of rooms at night. Designed by French company Beauer, the nesting camper is about 8.5 by 6 feet in its travel-ready configuration, but the shorter dimension turns in the longer one (15 feet) when deployed. Its fixtures conveniently slot into place, unfolding to become parts of a set of bedroom, kitchen, living and dining areas (complete with refrigerator, stove, microwave, sink and toilet).
