Since we invented the very first self-inflating camping mattress in 1972, Therm-a-Rest has been committed to creating the finest portable outdoor comfort solutions for every kind of adventure. Our product offerings represent the leading edge of innovation across mattresses, sleeping bags, cots, pillows, hammocks, and more, with the majority of it made in the USA, where it all began over 40 years ago. However you enjoy the outdoors, having Therm-a-Rest comfort along for the ride makes it better.
Are you always on the lookout for something bigger and better? Your ship has arrived with the MondoKing 3D. Simply put, the MondoKing 3D is the biggest Therm-a-Rest mattress ever. Vertical sidewalls create 20% more usable sleep surface so you have room to sleep like starfish. Dual valves allow compressible foam core to expand and inflate quickly when unpacked. A new and improved stuff sack with easy-carry handle is also included.
The Therm-a-Rest Mondo King 3D Self-Inflating Foam Camping Air Mattress is the most luxurious option in the Therm-a-Rest mattress line. Second only to a home mattress, this camping pad is designed with ultimate comfort in mind. Perfect for car camping, expedition basecamps, RVs, and boats, it also makes an excellent guest bed at home. The foam core self inflates, and deflates, quickly and easily through two valves; no air mattress pump is required. Firmness can be adjusted with a couple of breaths into the value for customized comfort. Vertical sidewalls provide more surface area, compared to a traditional ground pad, and allow two of the same mattress to mate perfectly when paired together to create an extra-large air mattress for two people. The stable urethane foam core of the mattress offers maximum stability, cushioning, and protection from rocks, roots, and uneven ground surfaces. And with 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 Therm-a-Rest Mondo King 3D Self-Inflating Foam Air Mattress is one of the warmest portable mattresses available. Roll it up and take it anywhere a good night’s sleep is desired using the included stuff sack with convenient carry handle. Available in two sizes: Large measures 77 x 25 x 4 inches (7 x 26 inches rolled) and weighs 5.5 pounds; XXLarge measures 80 x 30 x 4 inches (7 x 31 inches rolled) and weighs 6.75 pounds.
