Luno makes a smart product: Air mattresses custom-fitted to over 1,800 different vehicle models. The self-inflating mattresses turn the back of your station wagon, hatchback or SUV into a comfortable, flat sleeping surface, bringing car camping to the next level.

Since we last looked in on them, they've expanded into what was previously unusable territory for sleeping: The front seats of a camper van. Luno's new offering uses a bottom unit that fills the voids up to the level of the seats…

…then gets covered with the top unit, creating a comfortable sleeping surface.

It inflates via the included rechargeable cordless air pump.

While an adult can fit in a pinch…

…it's really designed for kids or pets. Even still, that's one less body you need to put in the back, which leaves more room back there for adults.

The Luno Front Cab Air Mattress can be ordered for the Mercedes Sprinter, Dodge ProMaster, RAM ProMaster, Winnebago Travato and Solis and runs $400.
