    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 198 x 66 cm, 198 x 76 cm, and a double-wide 198 x 132 cm.

    Exclusive 4-way stretch top

    All other camp mattresses use tightly woven fabrics that do not stretch. These surfaces transfer weight across the mattress and can feel both stiff and "bouncy". Our Flex™ mattresses feature an exclusive 4-way stretch fabric that forms instantly to your shape and movement, both minimizing weight transfer and relieving pressure points.
