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. 🥰

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 Amazon 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.

I have used this mattresses a couple of times, and it is now my favorite one for car camping. Since it is well insulated it keeps you warm in colder weather. The larger size means plenty of room, and it is comfortable. Seems very durable too, unlike the standard air mattress I used before that got multiple holes in it when the plastic got old after a few years. The Thermarests seem to last forever.

The Mondoking is hands down the most comfortable sleeping pad I have had the pleasure of using. I backpack and camp a lot where I live in Colorado. With the weight it is by no means a backpacking pad, however, it is amazing while car camping with my family. If you don't have to hike too far, a few miles even, this is amazing. Anything beyond that, I would recommend more of a backpacking inflatable pad. It is SUPER comfy and SUPER warm. The coldest I've slept on it so far is about 18°, zero cold spots whatsoever. I'll give an update after torture testing this when I winter camp later this year. Great buy!

I’m 6’4â€, 280 lbs and prefer to sleep on my side. $30 mattress weren’t cutting it when camping with my family. I was excited about finding the highly reviewed Therm-a-Rest MondoKing 3D Self-Inflating Camping Sleeping Pad, so I bought the XXL 80x30 inch model. Unfortunately it didn’t self inflate and I didn’t want to blow it up with lung power. So I bought a Diswasher Disposer (7/8 to 5/8 connector) that perfectly attached a bellow foot pump to the mattress’ “IN†valve. Looking forward to the first night of sleeping on it.

This had a reputation of being very comfortable, and I agree. I have it on a cot in a back room of my apartment. I've slept on it a few times, and find it almost as comfortable as my bed. I sometimes travel cross-country on adventures, and sleep in the back of my car, a Subaru Outback. I haven't tried it in the car yet, but I'm sure it will be more comfortable than things I've used in the past! It fits in half of the rear cargo area, with will work with some tricks & adjustments for my height (6 ft.). It could easily be moved from my car to a tent.One trick to consider. don't overfill it. I found it much more comfortable after I took a bit of air out of it.

We bought 2 of these sleeping pads to use during a move while we waiting for our household goods to arrive. We also purchased a Therm-a-Rest NeoAir Micro Electric Air Pump. After 4 nights of sleeping on the floor on half-inflated mattresses (the pump only filled them partially), we decided to try blowing into them by mouth. It only took about 6 breaths each to bring the mattresses to compacity. What a difference it made! We were miserable the first 4 nights on partially inflated mattresses, but once the mattresses were filled we were much more comfortable. Then we placed them on our Disc-O-Bed XL Portable Cot Bundle (purchased at Costco) and were as comfortable as in our own Select Comfort bed! Recommended!

I bought two Therm-a-Rest MondoKing 3D Self-Inflating Camping Sleeping Pad from Amazon.com on 6/25/2023. My wife and I have used them only for 3 times. It turned out that one sleeping pad is slowly leaking air. At night, before I was using it, I pumped air until it was a kind of firm and supportive. However, in the next day morning, the pad became not firm at all, and I can even touch from the top surface to the bottom without much force.I submitted my first request for replacement of the pad (it is still under warranty) at the company's web site on 12/23/2024 and there has never been replied by the company customer support personnel except the automatic reply. Then I submitted another same warranty request on 1/9/2025. Up to now, no reply at all.What a worst experience with this product and the company warranty supports.

Tried using this sleeping matt on a -2 degree celsius night in my backyard. Not only was it super comfortable it kept me warm all night! I definitely recommend it.I am a 165cm woman and I fit decently well on the matt. For larger people you might need to order an xl version. Greetings from Belgium!

The Therm-a-rest MondoKing XL is well worth the extra cost compared to other SIM’s, we slept 5 nights on the bed and they’ve not required any additional air since setting up the tent. 2 x XL SIM butted together with a king size base sheet provided excellent nights sleep and I am 6’5â€.Please remember to read the instructions and allow the mats to self inflate for an hour or so before use and then add a little top up of air.

Fantastic sleeping pad! Had an issue with the valve and amazon helped to replace it.

Die Matte ist ein Superlative. Man liegt wie auf einer Matratze, super komfortabel und bequem, dazu warm. Die Matte ist super leicht. Der Preis ist gerechtfertigt.
