    Can't see anyone not liking this

    • Familiarity: I've put it through the wringer

    Works great. Comfortable as all hell. Wide and long for large people. This is a car camper dream. Use it for guests that drop in at your house too. Worthy of adding to your gear stockpile

    Side sleepers - keep on looking

      Like all Thermarest products, it self inflates as advertised. However, foam is fairly dense so even though really thick, it's somewhat hard. I was expecting a much softer pad than this. I am a side sleeper and always looking for something that is going to let my shoulder sink down into it. Not so with this. Put some air in a 2" thermarest, close the cap and it feels about same. I never slept on it for a night, but I could tell just laying on it that it would not be comfortable. Next and perhaps biggest issue is rolling it up. It is incredibly difficult to roll this thing up. I had to have me (200 lbs) and my son (230 lbs) sit on it at ever turn to get it small enough to fit in stuff sack. Plus, the denseness of foam fights you at ever roll. I thought this would be great for multi-day raft trips, but its not. If you are looking for a car camping setup, stick with a traditional thermarest on top of a cot. Much better setup and with the size of this thing even rolled up, not much more space!

      Needless to say I am returning this.

      The Ultimate Glamping Pad

      • Familiarity: I've used it once or twice and have initial impressions

      I love this pad for car camping. It is huge when rolled up, so definitely not useful for other types of camping, but when the space is there, this will be my go to. I slept super soundly on it and finally didn't feel like my hip was digging into the ground. The self inflating is really nice too. I would recommend this to anyone that is looking for a good night's rest while doing some car camping.

      Sleep like a princess

      • Familiarity: I've used it once or twice and have initial impressions

      This sleeping pad is amazing, it's self inflating foam means I don't have to break a sweat pumping it up. It's super thick and long. I used to use an Exped SynMat 7 which squeaked every time I moved but no more squeaking with the MondoKing! The drawback is that this pad is definitely only for car camping due to it's rolled up size (my friend thought I brought another tent that's how large the sack is) but other than that it is an excellent product if you want to sleep soundly through the night and feel as if you were sleeping in your bed at home.
