With a supportive structure and well-designed features, the highly rated Exped MegaMat delivers impressive comfort, bringing a high level of sleep quality to camping trips.

A quality sleeping pad can make or break a camping trip, especially when nothing ruins a night faster than feeling like you’re sleeping on the hard ground. While I’ll compromise a bit on comfort when backpacking, car camping trips are a different story. A thick, well-cushioned pad makes sleeping outdoors feel more comfortable and helps me wake up refreshed and ready for the day.

In terms of what I look for in a camping mattress, I tend to prefer self-inflating pads, since the foam makes them extra comfortable and they’re quick to set up. A high R-value is important, too — it keeps the cold from creeping up through the ground and helps me stay warm all night. I also make sure the pad fits the spaces I’ll be using — whether that’s on the ground in my tent, on a cot, or on the bed platform in my Honda CR-V.

I bought the MegaMat to replace an older sleeping pad that developed a leak I couldn’t locate to repair, and after three trips spent waking up on a flat pad, it was time to upgrade. Focusing on the size I needed, comfort features, and price, I ultimately chose the MegaMat based on its reputation as a high-quality, durable sleeping mattress.

Comfort & Fit

I chose the Medium Wide size (72″ x 25.6″ x 4″), which works equally well on my car-camping bed platform and on the cot I use in my tent. The 4-inch-thick open-cell foam and vertical sidewall construction are a big part of why this pad is so comfortable. It stays supportive across the entire surface, feeling stable when I move at night instead of collapsing at the edges, and the combination of foam, sidewalls, and horizontal air channels provides just enough flexibility to adjust as I shift positions.

The soft, 100% recycled 4-way stretch polyester surface cradles the body and reduces pressure points, especially for side sleeping, adding next-to-skin comfort that isn’t rough or scratchy. The air-core-channeled foam also helps reduce weight and bulk, making the pad easier to roll and transport, while the bottom and side fabrics are made from 100% recycled polyester laminated with TPU, providing durability without adding unnecessary weight.

Setup is quick thanks to the self-inflating design, and the included Top-Up pump allows me to fine-tune firmness exactly how I like it. The valve system is simple and intuitive, making small adjustments easy without losing much air, and deflation is just as fast. The SideWinder roll-top storage bag with its side opening makes rolling and carrying the pad much easier than a traditional stuff sack, and a welded carry handle adds convenience for moving it around camp. At home, I store the MegaMat fully inflated rather than compressed, which helps maintain its loft and longevity.

Compared to similar pads I’ve used, the MegaMat is noticeably more comfortable, and the combination of foam support, vertical sidewalls, stretchy surface, and forgiving construction delivers a sleep experience closer to a real mattress than other car-camping pads I’ve tried.

Inflation, Deflation & Ease of Use

The MegaMat self-inflates quickly thanks to a one-way, low-profile inflate valve. For faster inflation, the included valve pin can be inserted to speed air intake. After the mat self-inflates, I can top it off to my preferred firmness using the included Top-Up Pump. Adjustments are easy: opening the valve and pressing gently on the one-way flapper lets excess air escape, letting me customize the feel perfectly.

Deflation is just as efficient thanks to a high-air-flow deflate valve. The SideWinder roll-top stuff sack makes storing and transporting the mat much easier, thanks to a wide side opening that makes it simpler to place the pad into the bag. It does take a bit of effort to push all of the air out to get the pad compressed enough to fit, and I wasn’t able to get it quite as small as it was when it arrived — but it still fit into the storage bag without issue. The pad also includes a small repair kit for field fixes.

A welded handle on the side adds convenience for carrying the pad. At home, I store the MegaMat fully inflated rather than compressed, which helps maintain its loft and longevity.

Warmth Across Seasons

The MegaMat has an R-value of 8.1, which measures how well a sleeping pad resists heat loss to the ground — the higher the number, the better the insulation. This makes it an excellent choice for cold-weather camping. I’ve used it on multiple trips to the Oregon Coast in late fall and winter, sleeping in a tent on the ground, on a cot, and in my car, and it’s consistently kept me warm.

I’ve also used this pad in warmer conditions, and it hasn’t felt overly warm. While it really excels in cold temperatures, it doesn’t trap excess heat when conditions are milder, making it a solid year-round option.

Sustainability

The environmental impact of the gear I buy matters to me. It’s nice to see outdoor companies making an effort, and Exped has a strong approach: they offset emissions from production and transportation of their products, including the MegaMat, which is PFAS-free, made without harmful chemical treatments, and constructed with bluesign approved textiles and a top fabric made from 100% recycled materials.

Overall, I’ve found that the Exped MegaMat combines high-quality construction, exceptional comfort, and well-designed features. The stable sidewalls, supportive foam, and stretchy surface make it feel closer to a real mattress than most camping pads, and thoughtful details — like the valves, SideWinder storage bag, and side handle — make it easy to use and handle.
