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.
Introducing the Base Mattress — Reliably comfortable, warm, and durable, the Base Mattress is perfect for any car camping or backpacking trip, and is a great option if you’re upgrading from a closed cell mattress or buying your first camp pad.
The Base Mattress achieves an all-season, ultra-warm R5 with the same premium foam core found in our Flex Mattress and pairs it with a durable 75D Polyester Taffeta for a no-frills mattress that delivers. The Base Mattress is self-inflating, but for faster manual inflation you can pair it with an Inflation Dry Sack (not included). The smart reversible valve allows you to inflate it with ease, and dump air quickly when you’re ready to pack up and head home.
The Base mattress is everything you need, and nothing you don’t—a tried and true mattress that will give a good night’s sleep no matter where you are.
Inflation Dry Sack sold separately.
Warm — The foam-insulated Base Mattress is unusually warm, offering an R-value of 5 for all-season warmth and EN-matched performance.
Durable — Constructed with a sturdy 75d Polyester Taffeta for both the surface & base of the mattress to provide long-lasting durability in the outdoors.
Portable — Suitable for backpackers and car campers alike, the Base Mattresses start at 1 lb 12 oz and pack down to roughly 10" x 5" in size.
Easy Set Up — The Base Mattress's reversible valve keeps air in while inflating and out while deflating, making set up and take down easy. The Base Mattress is self-inflating, but the valve is compatible with our Inflation Dry Sack for faster manual inflation. Inflation Dry Sack sold separately.
