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. Also note that 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.

3D! — The completely flat top and vertical side wall make the Flex™ 3D Mattress feel like a real mattress. The top is usable from edge to edge and it cradles you like your mattress at home.
4-way Stretch Top — 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.
Horizontally-cored Foam Insulation —Horizontally-cored foam eliminates the cold spots found on most vertically-cored mattresses and delivers an R-value of 7.
Fast Inflation - The included Inflation Dry Sack is sized perfectly for the fastest inflation time and doubles as storage for the mattress.
Reversible 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.
