Always on the lookout for something bigger and better? Look no further than the Therm-a-Rest MondoKing 3D Self-Inflating Foam Camping Mattress. Simply put, the MondoKing 3D is the biggest, plushest Therm-a-Rest mattress ever. Vertical sidewalls create 20 percent more usable sleep surface so campers have room to sleep like starfish. Dual valves allow compressible foam core to expand and inflate quickly when unpacked and only requires a few breaths for ideal firmness. Vertical sidewalls maximize the usable sleep surface and 4 inches of stabilized loft provides the comfort of home anywhere. Supple stretch-knit fabric covers a deluxe sleeping surface that is both breathable and plush, while a foam core delivers all-season warmth, boasting an R-value of 11.4 (R-value measures the material’s ability to insulate; the higher the R-value, the warmer the sleeping pad). The MondoKing 3D also mates perfectly with other Therm-a-Rest 3D mattresses. The Therm-a-Rest MondoKing 3D is available in 2 sizes: Large measures 72 x 25 x 4 inches, packs to 26 x 9 inches and weighs 5 pounds 8 ounces; XXL measures 80 x 30 x 4 inches, packs down to 31 x 9 inches and weighs 6 pounds 12 ounces.
