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.

A 3-inch thick mattress is the perfect height. It provides enough thickness for the mattress to feel bottomless in most every sleep position and it doesn't take up too much head room in your tent or car. It works everywhere! Even in smaller tents.
A group of friends planned a camping trip this year and all I could think about was how miserable I was last year trying to get a good night rest and how it ruined the rest of the trip. I was determined not to make the same mistake again, so I bought the Double Sleep system and the flex 3D Mattress for this trip. I have never been so comfortable as I was this trip. The temps were right at freezing but with the 25 degree quilt and the Flex 3D Mattress I slept like a baby. Side sleeping, on my stomach, it didn’t matter. Its well worth it so treat yourself, you won’t be disappointed.
So far so good. I will be using these for motorcycle camping have not got a chance to use it outdoors yet but I’ve used it for a week solid in the house on the floor and seems wonderful have no complaints or no regret great product!
I've done a fair amount of sleeping in tents using all different kinds of sleeping pads. I wanted something that would fit my partner and myself while car camping, but wasn't a blowup mattress, had a high enough R-value to keep warm in all 4 seasons, set up quickly and wasn't too bulky for packing in the car. This thing was fantastic upon first use. I'm hoping it holds up over time. The inflation sac helped inflate 50x77 size in about 5-7 minutes. Probably the most comfortable I've been camping in a tent. I couldn't feel it at all when my partner would move around or get out of the tent during the night. Stayed inflated for 2 days with no re-inflating necessary. Kept very warm, it was about 35 degrees out both nights. Pack up was extremely easy, deflates quickly and rolling it up was not a problem. I'm really looking forward to using this more often. It's definitely expensive, which is probably the only downside to this product. I shopped around for a bit before deciding on this. There are similar products for about the same price and a little lower but don't have the features of the 3-D Flex Mattress. I'm surprised I'm the first review here. If you're in the market for something like this, and don't mind the price tag, this thing is incredibly comfortable, easy to pack, set up and take down. The real test will be how long it lasts! I'll have to report back in a few years.
Myself and my partner are both slimmer builds each at about 5'7'' tall. Fit us very comfortably with room to spare.
