We encourage everyone to experiment with different sleeping options before investing in a sleeping platform. Depending on the shape of your vehicle’s interior, an air mattress on the floor may work fine in a pinch. Our customers, however, are quick to point out that their back seats don’t lay down flat. And there’s a gaping hole between the 2nd row seats and the 1st row seats. So a mattress on the floor makes for a lumpy bed with a drop-off on one end. And comfort aside, when you put a mattress on the floor, you have no room for your gear. By lifting the bed up off the floor of your car, you solve both problems at once. PS, a raised sleeping platform also allows your mattress to breathe and offers increased airflow while you sleep!
