The Coleman Single High QuickBed Full Air Mattress is firm and comfortable, even though it's low to the ground. Because of the flocked rayon top and the heavy-duty PVC material, this bed provides durable luxury. The unique feature of this bed is not only it's sturdy material but also it's design: the circular coils along the surface ensure an even and satisfying sleep. It comes with a double lock valve to secure the air after inflation. When the night is over, the Wrap 'N' Roll system makes clean up quick and simple.
