    • The most comfortable camp mattress ever designed. Our 4-way stretch fabric allows this mattress to “flex” with your shape and movement, so the top feels softer and more supportive than other camp mattresses - even at firm air pressures. Our slow-deflation valve feature allows for customizable comfort. Simply lay on the mattress and push the "button" to slowly deflate to the desired firmness until it feels as close as possible to your bed at home. Horizontally cored foam eliminates the cold spots found on most vertically cored mattresses and delivers a full R-value 5 for EN-matched performance.

      Long gone are the lightheaded days of blowing up your mattress by breath. The Flex Mattress includes our Inflation Dry Sack for easy inflation in under a minute. Simply snap the Inflation Dry Sack onto the mattress valve and push the air through.

      Includes the Flex™ Mattress, Inflation Dry Sack, and repair kit


    The Flex™ Mattress


    180g of fully-baffled insulation is considered excessive when compared to most air mattresses but actually it's the minimum required to achieve R-value 5+

    Horizontally-cored Foam

    Horizontally-cored foam cuts weight and eliminates the cold spots found on most vertically-cored mattresses and delivers a full R-value of 5 for EN-matched performance.

    Our 4-way stretch fabric allows this mattress to “flex” with your shape and movement, so the top feels softer and more supportive than other mattresses, even at firm air pressures.

    Supportive 4-way Stretch

    Our 4-way stretch fabric allows this mattress to “flex” with your shape and movement, so the top feels softer and more supportive than other mattresses, even at firm air pressures.

    Reversible Valve

    The reversible valve keeps the air in while inflating and its slow-deflation "button" lets you dial in your exact comfort level. When it's time to pack up, the entire valve pops out for fast, hassle-free deflation. Snap it back in in "deflate" mode and the air stays out as you continue to roll.

    Included Inflation Dry Sack

    While the Flex™ Mattress will mostly self-inflate once you pop the valve open, it's helpful to have an Inflation Dry Sack to top it off to your desire comfort level. The Flex™ Mattress comes with a fully-welded Inflation Dry Sack for waterproof storage and easy manual inflation.

      Base Camp Worthy

      Comfortable and warm no doubt. Big and heavy compared to others on the market yes. I expect it to be heavy with an R value of 5 so that’s not a problem. The 2 star for me comes down to the stuff sack. It’s too small for the pad and ripped the second time I tried to put the pad in. As someone who packs up camp every morning and is on the go, this one just plain doesn’t cut it. It would be great left at basecamp with a bigger after market stuff sack.

      Unbelievably comfortable

      I bought this mattress because I was planning a longer camping trip. I´m used to sleep on camp beds and I was amazed how comfortable this mattress is in comparison.

      Impressive

      Just wrapped up a 3 week overlanding backcountry discovery routing tour of AZ, CO, and WY camping most of the time in a range of temps, mostly below 40 at sunrise. Ages at 53 and 76 years of age, both on tent cots using the 30x80. Filling and deflation with a flex air pump in less than a minute. What I like: Comfort. Warmth, but not hot. What I don't like, but can't change: size when deflated. Obviously these are heavier, larger beds made for car camping but with benefit of a smaller form factor than other cheaper self inflating foam beds and way more comfortable than the featherweight krinkly small form factor varieties. We had Nemo and Puffle tops but I trust the Zenbivy brand to incorporate their quilts and other sleeping gear. No pressure loss by mornings and no "cold" spots sleeping directly on the pads, really impressive. I believe it was the pad that saved me one 25 degree morning under a 40 degree quilt with a cheap top quilt. I've used other brands of air pads that pack down, but they are loud, cold, and leak. Not so with these two so time will tell....

      Mattress was great but sack needs to be bigger

      I just bought 25X72 and 25X77 flex mattress for my camping trip in early May. The mattress performed wonderfully, easy to inflate, comfortable and did not feel cold which was my concern being from Canada. I do have issues with dry sack though. I was able to pack 25X72 comfortable but sack is too small for 25X77. Even though all the air is out it does not fit the sack. Considering the price Zenbivy should consider making a bigger sack for bigger sizes.

      Game Changer

      I'm finally able to sleep comfortably on my side while camping! This pad is warm, comfortable, and quiet. It's a little bulky when packed down but that's a small price to pay for a great night's sleep. My Zenbivy sleep systems were well worth the money, and customer support is outstanding.
