Design & Build Quality
The Exped MegaMat Ultra has a refined design that balances durability with comfort. As you can see above in the images, its surface sports a soft recycled polyester tricot fabric that feels gentle against your skin. This is a noticeable upgrade over basic foam camping mats or rougher air mattresses, making it ideal for those who value a luxury sleep experience outdoors.
The mattress boasts a substantial 10 cm thickness with 3D vertical walls around the edges. This design element significantly increases the usable sleeping surface while maintaining stability and support. The microfiber insulation is carefully welded inside the air chambers, meaning the warmth you get is superior to many traditional foam pads. This insulation technology also keeps weight down for better packability.
One user commented how the MegaMat feels like “sleeping on a cloud in the forest,” highlighting the combination of softness and insulation. The materials used are also robust enough to withstand outdoor challenges without undue wear, giving users confidence that it will hold up for many trips.
The pack sack doubling as a pump is an ingenious touch. It reduces the number of separate items to carry and makes setting up faster. The overall build quality feels premium and purposeful, perfect for serious campers who want a hassle-free yet indulgent sleep option.
Real-World Performance
In practice, the Exped MegaMat Ultra excels at turning high-end specs into real comfort and usability. On a recent car camping trip, setting up the mattress took mere minutes. The self-inflating action got things started quickly, and a few easy strokes with the pump sack brought it up to full height comfortably.
Lying down, I noticed the thick 10 cm cushioning provided excellent support and kept me insulated from the hard ground below, even when temperatures dropped at night. Unlike thin foam pads or less insulated air mats, this MegaMat kept the chill off, providing deep, restful sleep. The large sleeping surface allowed me to stretch out fully without feeling cramped or restricted, a real boon after long days outdoors.
Another benefit was the simplicity of packing it away. The extra-large valve meant I could quickly let the air out without fuss. The mattress then rolled up compactly into the pack sack, making it very manageable to transport.
For backpackers or cyclists wanting a mix of comfort and ease of use, this mattress strikes a strong balance. It’s also well-suited for SUV adventures, where space is less of a constraint but sleep quality remains critical. The microfiber insulation and 3D wall design are standout features that deliver noticeably warmer, more stable sleep compared to standard pads.

What Makes It Stand Out?
Compared to other premium camping mattresses, the Exped MegaMat Ultra shines in a few key areas. For example, the Therm-a-Rest NeoAir Camper SV also offers insulated air mattress technology but usually comes with a thinner profile and smaller sleeping surface. The MegaMat’s 10 cm thickness and wider dimensions cater to users who want a more luxurious and spacious sleep without sacrificing insulation.
Another competitor, the Sea to Summit Comfort Plus Insulated Mat, offers excellent warmth with multi-layer construction but tends to be more complex in setup due to dual chambers requiring separate inflation. Exped’s 2-in-1 pack sack pump system streamlines the inflation process, making it more user-friendly, especially in cold or low-light conditions.
Additionally, the recycled polyester tricot surface on the MegaMat provides a softer touch, which some users prefer over the more textured or slick materials used on rival offerings. This improves comfort through the night and reduces slipping or bunching of sleeping bags.
Overall, Exped has combined smart design choices: microfiber insulation welded inside the air chambers, a self-inflating system, and a roomy sleeping area, making it a unique option for high-end campers who prioritize easy setup and a premium feel outdoors.
