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.

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 Light Mattress has an R-value 5+ for EN-matched performance and all-season warmth: no cold spots.
Quiet Comfort - No crinkly chip bag sounds here! With 180g of fully baffled synthetic insulation, the Zenbivy Light Mattress is quiet and built for undisturbed sleep.
Fast Inflation - The included oversized dry sack is sized perfectly for the fastest inflation time and doubles as fully-welded storage to keep the mattress reliably dry on the trail.
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.
Light and Soft - The soft 20d polyester taffeta shell is comfortable enough to sleep on directly while still being durable and lightweight, making it the ideal mattress for backcountry trips.
(Note that only mattresses with R-value 5 or greater will deliver full temperature rating performance from EN-rated sleeping bags)

Perfect length I’m 6’2
This mattress has been among the most comfortable that I have used, but on my second use I had a leak. I followed the instructions on how to patch it up, but the sealant did not work the first time. I ended up using the sealant a second time and a patch for reenforcement. I enjoy the pad I just wish it was a bit more sturdy.
So far I've used my new mattress on two trips and it's been very comfortable so far. It's easy to inflate with the included inflation sack (and easy to roll back up and fit into the sack) with the help of the reversible one-way valve. After much deliberation, I decided to size up to the 25x77 mattress and I'm glad I did. I was worried it would be too long for my two-person tent but its a perfect fit. Looking forward to trying it out on another trip in the Ontario backcountry later in the year to see how it performs in lower temperatures.
It doesn't look like much but after inflation I found that it holds up very well. I weigh 200 lbs and I'm a side sleeper but no part of my body touches the floor. Add the sheet and quilt and I was comfortable all night.
I recently purchased a Zenbivy sleeping bag for my 13 year old. Dillon loves his new gear and can't wait to try it out this summer on his first ever back packing expedition. I am also impressed with the customer service -- patiently answering all my concerns.
