## Description

Sleep like camp royalty with the ultra luxurious Therm-a-Rest MondoKing 3D Self-Inflating Foam Camping Mattress. With couples in mind, the pad can be paired with a second MondoKing for a double sleeping pad. The pad offers an R-value of 7.0 for maximum year-round comfort thanks to thick thermal foam and StrataCore construction, which uses a continuous layer of thermal foam nestled between alternating ridges of air and foam (R-value measures the material’s ability to insulate; the higher the R-value, the warmer the sleeping pad). Perfect for car camping, expedition basecamps, RVs, and boats, it also makes an excellent guest bed at home. The stable mattress offers maximum stability, cushioning, and protection from rocks, roots, and uneven ground surfaces. All styles have dual valves that allow compressible foam core to expand and inflate when unpacked, and all styles mate perfectly with other Therm-a-Rest MondoKing mattresses with a similar style. Available in three styles: Equipped with the Standard Valve with the 2018 or 2019 model, or equipped with the TwinLock Valve the sleeping pad has dedicated "in" and "out" valves to make inflating and deflating the pad easier than ever. Standard Valve models are 4.0 inches thick inflated and include a stuff sack, and TwinLock Valve models are 4.5 inches thick inflated and include a stuff sack that can also be used as a pump sack (for easier, breath-free pad inflation). Made in the USA. Manufacturer’s limited lifetime warranty.

Review: Best camping sleep for the money. - The only thing I dislike about this, is that it didn't exist sooner. 😂 Easily the best camping air mattress I've ever used. It felt like sleeping in my own bed, because of the foam, it's great. I slept well, all night, on the ground, in the woods. No tossing and turning, and I felt rested in the morning. It's not loud or makes weird noises when you move around on it, and it feels soft to the touch instead of plastic or something. It will basically self inflate, but the bag it's stored in can be used as a pump, which is neat, but I bought the tiny pump for it. Inflates in under 10 minutes I think. It's a bit bulky, not for backpacking but if your worried about your back and want to camp, use this mattress, my 75yo dad approves. 👍 It seems well built and can support my fat butt so I recon it will yours too, and be comfy. 🥰
Review: Most comfortable - Consider me the princess of the princess and the pea. I’ve tried everything. I had settled on bringing an air mattress when camping. But I was frustrated by 2 things: the cold and having to inflate it multiple times. Never mind how big it is and the fact that I needed a separate tool to inflate them. I have tried many sleep pads from desertcart and with each one, I woke up multiple times during the night with soreness. I didn’t inflate this all the way the first time, and I didn’t know what all the fuss was. I added more air and WOW! It not only helps to keep your body heat from being sucked out, but the comfort is unreal. I never felt the ground and my joints felt supported. It is easy to inflate, let it do it’s thing, then add manually to your firmness preference. It’s also super easy to deflate and it packs smallish. If you are having trouble getting comfortable camping, buy this. It’s a game changer for car camping.

### ⭐⭐⭐⭐⭐ Easy to inflate
*by B***U on July 6, 2020*

Inflate very quickly and they designed the carry bag to be the pump sack which is a great idea, no need to carry extra item or a mini pump (my wife had an Exped), it also pump much easier than any mini pump since it hold a lot more air and you just push it down. Quick inflating tip, use your camping fan to blow air into your pump sack, much quicker, each pump will be a full bag of air :) Don't expect the bed will just self inflated completely, pump few more times to get to the firmness you want. Twin lock value make it super easy to let some air go if it is too firm and quick to deflate and pack up (compare to my wife's Duo... so difficult to pack it small) It hold its air for days no issue, I even left the inflate value open to test it, no leak for 3 days, so should be enough for most camping trip? It is comfortable sleeping on it, I'm 200 lbs, and can't feel the ground when roll it on my side
