Zenbivy Mattresses
The success of a sleep system relies heavily on your mattress. If you've ever experienced a cold sleepless night outdoors, you know how quickly it can turn a good trip very bad. The mattress you pair with your sleeping bag should provide you both comfort and warmth. Zenbivy Mattresses are properly insulated with an R-Value of 5+ to match the stated temperature ratings of not only our Beds, but all EN-rated sleeping bags. Stay warm, sleep soundly.
The Flex™ Mattress is perfect for those that want maximum comfort when they set up camp, whether that's in a developed campground or on top of a mountain. The Light Mattress is a great mattress for the avid backpacker that looks for comfort at the lowest possible weight and bulk. The Flex™ 3D Mattress, a luxuriously comfortable 3-inch thick version of our original Flex™ Mattress, is optimized for car camping.
NEW! Flex™ 3D Mattress
Shop
Our new Flex™ 3D Mattress is a luxurious 3-inch thick horizontally-cored foam mattress optimized for car camping. The 4-way stretch fabric allows it to "flex" with your shape and movement so the top feels softer and more supportive than other camp mattresses—even at firm air pressures. It's the ultimate in car camping comfort.
Available in 25x77, 30x80, and our new double-wide size: 50x77
Real Insulation. Real Warmth.
Both the Flex™ Mattress and the Light Mattress are fully insulated to deliver an R-value of 5 for EN matched performance.
Reversible Valve
All Zenbivy mattresses have a reversible valve. When in "inflate" mode, the valve keeps the air in while you're working to inflate it and allows for customizable comfort with its slow-deflation feature. When it's time to pack up, the entire valve pops out completely for fast, hassle-free deflation. Then flip the valve over to "deflate" mode, snap it back in, and the air stays outas you continue to roll!
Easy, Manual Inflation
Long gone are the lightheaded days of blowing up your mattress by breath. Both the Flex™ Mattress and the Light Mattress include our Inflation Dry Sack for easy inflation in under a minute.

Soft & Warm
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+, allowing you to get full EN rated performance from your sleeping bag.
Built for Undisturbed Sleep
With a shell made of 20d polyester taffeta and 180g of fully-baffled insulation inside, you can say goodbye to the “space blanket crinkle” synonymous with most ultralight air mattresses.

Horizontally-cored Foam

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.
