Enough give for the crankiest back

by Tlyn, from CO, United States Updated on November 7, 2021

I had done lots of research on this MondoKing mainly because of the price involved with this mat compared to others. My husband and I plan on riding to SD on his Honda VTX and we couldn't find a way to lug an air mattress and pump. So, I began the search for something with plenty of give off the ground for my low back. I never thought I'd drop this money on a mat but so far 2 n...

Very comfortable

by Slimpickins, Verified Owner from TN, United States Updated on November 7, 2021

This mattress is just as described! Very comfortable, but it is very large. I wouldn’t take it backpacking, but for sure will use for truck camping. The self inflation is great! The deflation process is good also, just a little more tedious. It’s also a little tough to get the mattress back in the bag.

Would recommend: Yes

Really Comfortable

by Gary K., Updated on November 7, 2021

I am a side sleeper and find this mattress to be truly comfortable. I find is best when letting it inflate itself and not adding additional air for more give. If only it packed smaller and were lighter… I could take it backpacking. However, for car camping or when doing events that involve camping (and someone else is schlepping by gear) it is terrific!

Would recommend: Yes

Don't buy just one, get two!

by Spencer H., Verified Owner from WA, United States Updated on November 7, 2021

This bed is very comfortable and a great size for myself. I'm 6'3" and a slender 190lbs. Plus I'm a side sleeper. I let the bed inflate on its own and that enough for me. Some may like it firmer and that will also keep you from having a sore shoulder or hip if you're on the heavier side. I'm actually about to buy another one and just stack them for my every night bed. If someon...

pretty awesome

by Kerri T., from TX, United States Updated on November 6, 2021

ok, so I have used it on 3 camp outs so far. the more I use it the happier I am that I got it. this seems to be a fairly new product out there so not many reviews on it. sleeping wise it is great. Kind of a pain to put back in storage bag, as all self inflating pads are. I have not used it on a back pack trip yet, little bit on the big side, but if comfort is a must for sleepin...

Nice but....

by Doreen B., from NE, United States Updated on November 6, 2021

I did not use the mattress to sleep on so I cannot comment on that. However, just for the few minutes I tried it, it did seem comfy and much better thank the traditional air mattress one can by at local box stores. The reason I returned it was for me it was very cumbersome to stuff back in sac and I needed to wrestle with it to get all the air out.
