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
All-Season Warmth - Only mattresses with an R-value 5 or greater will meet the thermal performance of EN-rated sleeping bags. Most mattresses on the market today that are advertised as “3-season” do not provide the warmth required to match EN-rated bags. The Zenbivy Flex Mattress has an R-value of 5 for EN-matched performance and all-season warmth: no cold spots!
Silent Comfort - Fall asleep and stay asleep. The Flex Mattress's horizontally-cored foam insulation makes for a silent night at camp. The 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.
Fast Inflation - The included oversized Inflation Dry Sack is sized perfectly for the fastest inflation time and doubles as fully-welded storage to keep the mattress reliably dry when packed.
Smart Valve - The one-way reversible valve keeps air in while inflating and allows for customizable comfort with its slow-deflation "button”. When it's time to pack up, the entire valve pops out for instant, hassle-free deflation. Then pop the "deflation" valve side back in and the air stays out as you continue to roll.
(Note: only mattresses with R-value 5 or greater will deliver full temperature rating performance from EN-rated sleeping bags.)

Locate your height on the ruler below to see which size quilt and sheet/mattress we recommend for you. Ideally, you'll want to fall somewhere in the middle of the range. If you find yourself in the yellow, you'll probably want to size up for the most comfortable fit. Please note that the chart below is based on the average weight for each height. If you are an "active" or "wide" sleeper, you may want to consider sizing up to allow yourself more space to sleep naturally.
When in doubt, size up. Unlike mummy bags, there is no thermal disadvantage to a larger size Zenbivy Bed because it is always free to wrap snugly around you. Bigger is always more comfortable and just as warm. Questions? We're happy to help. Send us an email with your height, weight, and general sleep style and we'll help you find the right size for you.
I’ve been using this mattress on and off for a few weeks now, it’s it’s been camping, in hotels, and just in my floor. I’ve never had a camp mattress so comfortable or quiet.
This is bar far the most comfortable and easiest to inflate pad I have seen. Highly-recommended. However, please note that the case for it is about at least 3" too short of the bag when rolled without folding. And to get the pad in the dry sack, you do have to roll it without folding. Folding it is an option, but it is then too think to get in the bag. Not sure why there was a mixup in the specs for the bag because it is good otherwise in design. Of course, having your pad stick out a bit on the end of the bag isn't the end of the world, and the pad is extremely comfortable.
Extremely well-made, can’t wait to use it again and again. If anybody’s looking for a serious sleeping bag that does it all this is the one.
the mattress is definitely comfortable to sleep in any position you desire, I move around a lot at night and was surprised how supportive it was while sleeping on my side, I don't feel the ground and my hip doesn't hurt in the morning. I sleep very well, and love how you can adjust the firmness. The plus is the bag that it comes in, and how it helps to inflate it so you don't have to get light headed blowing up your mattress. And after a long day of hiking you just want to relax. Only downfall is I wish it wasn't so bulky when it's packed up. I wish it folded down smaller I have to now attached it to the outside of my pack like I do my tent but it doesn't add too much more weight.
