The Flex™ 3D Mattress is the ultimate ultra-comfortable basecamp mattress. It features the same 4-way stretch knit top that makes our original Flex™ Mattress so supportive and soft. The 3D shape makes it feel just like your home mattress, with a completely flat top and vertical side walls, packing 3 inches of self-inflating horizontally-cored foam to give you the most comfortable night's sleep possible.
If you're a backpacker looking to upgrade their mattress for car camping trips or if you're simply looking for maximum comfort at camp, the Flex™ 3D Mattress is an ultra-comfortable and luxurious addition to your gear closet. Available in 25x77, 30x80, and a double-wide 50x77.
Includes the Flex™ 3D Mattress, storage/inflation sack, and repair kit
3D Shape
Why is a 3D mattress superior? 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.
3" Thickness
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.
Supportive 4-way Stretch
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.
Inflation Storage Bag
The Flex™ 3D Mattresses include an Inflation Dry Sack for fast manual inflation. The sacks double as storage bags for the mattress.

United StatesNot bad
Good quality and construction. But not as comfortable as I would hope for the money spent.

United StatesAmazing bed!
I bought this for back country also. This is so amazing! I have two degenerative disc’s in my lumbar so it was a must to buy this bed so I was comfortable and not hurting when I wake up in the morning after sleeping on the ground. I will be buying another one for my wife when I can.

AustraliaI guess you can’t get comfort without bulk & weight?
This mattress is super comfortable. Yes it’s also quiet and non slip. Yes it self inflates like a boss. But it’s so bulky when packed down. Not to mention heavy. It’s really only suitable for cramping with a vehicle. We have been using it as a spare bed for when our son has friends stay over. The straps and storage/inflation bag is the usual Zenbivy high quality. It’s hard to tell from the website how heavy and bulky something is. We would not have purchased this if we had handled it in person first. Honestly not sure what Zenbivy returns policy is for international orders but shipping to us was so expensive we didn’t bother trying to return the mattress.

United StatesHad given up on comfortable side sleeping until I found this!
At home, I sleep like a pancake, about 2 hrs on a side before flipping over all night long. When tenting, in the past, that has meant I wake myself up every 2 hrs hoping that I can lull myself back to sleep while my 225 lb frame is digging into the ground through my previous mattress and cutting off my circulation. In desperation for a good night's rest, I had retired my tent for an RV many years ago. So, I was skeptical that anything would enable me to return to tent camping, but the Flex 3D Mattress *far* exceeded my expectations. Due to its size, I'm guessing most will use it for car camping. But it is much lighter and more compact than any other comparable mattress, and I can't wait to stuff it in my backpack and panniers. Thank you Zenbivy! I'm so glad I found your products and so grateful I'll be able to sleep well outdoors while leaving the RV at home.

United StatesDouble Flex 3D Mattress 50x77
We overland out of our Jeep across the USA in the back country. We had been using our queen size air mattress in our Gazell tent but I thought this would be nicer. Myself, I like it being longer than our queen size blow up mattress since I'm 6'2" tall. It's soft and really doesn't take much air to get it blown up. My wife on the other hand says it hurts her back and I tried all different air pressures in it trying to make her comfortable to no avail. I like it myself and it is nice and warm with our Zenbivy double size down quit and sheet. IDK what to think I like it but she doesn't. I guess I win some and loose some. I like it!!!
