Therm-a-Rest MondoKing 3D Air Mattress


Self-inflating convenience with cozy comfort, the Therm-a-Rest MondoKing 3D Air Mattress offers 4 inches of loft – so you won’t feel that uneven ground, rocks or twigs. Dual valves allow compressible urethane foam core to expand and inflate when unpacked, and can be adjusted to ideal firmness with just a few breaths. Vertical sidewalls allow two pads to mate perfectly when paired together to create an extra-large sleeping pad for two people.
