MondoKing 3D Self-Inflating Camping Sleeping Pad

Pretty comfortable air mattress , good quality , easy to carry and store .

This is one of the most comfortable things I’ve slept on. Makes car camping/camping a breeze. I’ve used on hot nights and cool nights and if anything happens I’ll repurchase. Love my mondo king.

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. 🥰

Best mattress out there

Thin, weak nylon cloth covers all sides of the mattress. Very thin and very weak. Mine got a small tear in the cloth the first time I slept on it. I patched the tiny hole, but it got several more holes the next time I used it. The cover cloth is so weak that if you put your knee on the inflated mattress, it can be damaged. I now have more than 10 patches on holes I've found, but I've never been able to keep the MondoKing inflated overnight. It's just not made of sufficient material.

Purchased in May 2021, so lasted 4.5 years of moderate use. While sleeping on it last week Dec 2025), I heard a pop, followed by more and more pops throughout the night. The seams that keep the mattress’s integrity while full started to release. This allowed for uneven air distribution, rendering the mattress unusable. I paid $299 in 2021. It was good while it lasted however. Photo attached (that’s not a built-in pillow). Use this information as you will.

I've got a Thermarest backpacking pad that's nearing 30 years old and still as good as new (given the fact that self-inflating still requires some manual work), so when it came time to look for a camp sleeping pad it was naturally the brand I went with. As a side sleeper I went with the XXL (odd sizing, since there is no L or XL!), which is wider. It also fits perfectly on my cot. Instructions are accurate - self-inflation is good to a point, then the sack comes in handy to complete the job. One quick note here - plugging sack into the "In" port may be challenging. As with most air mattresses, there is some settling, but I found that after one top up of air it remained the same level of comfort for several days - you don't have to re-adjust air and comfort level every night. It's not so bad, but if you're a squirmer there will be noise. Deflating - this isn't quite as friendly, and why "Easy to inflate" lost a star (a deflate rating would have had 1 star). It is indicated that the "In" and "Out" ports efficiently block air going in the other direction. I'm not sure this is true. In locking down the "In" port so that no air enters and opening the "Out" to roll up for storage, every time I took weight off the deflating pad it would fill again through the Out port. It is a big challenge to get this pad back to a size that will fit back in its storage bag and that's why I returned it - in a different box because I never did get it small enough to fit back into its original. I can take down and pack my tent more quickly than I can pack this bag away. Sorry Therm-a-Rest, almost perfect.

I have slept multiple nights on it with zero issues. It is big, but man is it comfy. Definitely not a backpacking pad, but if you have the room in your car, you can't go wrong. I would even use this at home as a spare bed in a pinch.

自動空気入りの仕組みがあるのため、使いやすい。また、マットレスが厚いので、心地がすごく良い。XXL ver.を選らんたので、以前使った他のものに比べで、断然贅沢気分。

Ii cellophane che avvolge il materasso è arrivato rotto in più punti. Speriamo bene. Valutazione del materasso da confermare dopo l'uso.

Die Lieferung war schnell. Das Produkt erwartungsgemäß toll: Festigkeit justierbar, gute Größe, komfortables Schlafen! Allround top Produkt!

The most comfortable sleeping pad I have ever used or slept on. With an R value of 7 it will no doubt be suitable for all seasons. It feels very durable & the soft, stretchy material just adds to the comfort factor. Sure it packs large & is not exactly suited or designed for hiking or backpacking but after several punctures & leaks with expensive ultralight pads I would much prefer the security of knowing I will get a great nights sleep so I will make the extra bulk & weight work. 5 stars!

The most comfortable camping bed I've found, it's big and bulky but meant for car camping rather than carrying in a pack. Pair it with aa flex tail pump to fill it and in minutes you have a warm and comfortable bed ready!
