The most comfortable backcountry mattress ever designed is the perfect match for your Zenbivy Bed. 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 backcountry mattress - even at firm air pressures. The valve keeps air in when you inflate, then push the button to slowly deflate to the desired firmness - so it feels as close as possible to your bed at home. Flip the valve for deflation and the air stays out. Horizontally cored foam eliminates the cold spots found on most vertically cored mattresses, and delivers a full R value 5 for EN-matched performance.
The unique valve on the Zenbivy Flex Mattress pops out completely for super fast self-inflation and hassle-free deflation. The valve keeps air in when you inflate, then push the button to slowly deflate to the desired firmness - so it feels as close as possible to your bed at home. Flip the valve for deflation and the air stays out.
Sit back and relax while our high quality urethane open-cell foam self-inflates your mattress to life. The large valve hole allows it to fill quickly; then pop in the one way valve so air stays in while you top it off with a few breaths.
Most self-inflating mattresses have vertical cores to remove weight, but they also create cold spots. Zenbivy's horizontally cored foam reduces weight but eliminates the cold spots found on most vertically cored mattresses. And delivers a full R value 5 for EN-matched performance.
The Flex™ Mattress is designed as the perfect partner for your Zenbivy Bed and Zenbivy Pillow. A complete bed, designed from the ground up for the maximum possible comfort in the backcountry.Buy

Unlike mummy bags, there is no thermal disadvantage to a larger size Zenbivy Bed because it is always free to wrap snugly around you. So bigger is always more comfortable and just as warm. If you are an "active" sleeper or have a "wide" sleeping position, you may want to size up to sleep naturally. When in doubt, size up.
