Exped MegaMat Duo
For this season's top models, see our guide to the Best Camping Mattresses.
The Exped MegaMat Duo helped kickstart the luxury car camping mattress trend—and it remains one of the category’s most impressive designs. Simply put, this is about as close as you’ll get to sleeping at home while out in the woods. With 4 inches of plush, self-inflating foam, the MegaMat delivers outstanding isolation from the ground and a balanced mix of softness and support. It’s not quite as cloud-like as the all-foam Hest Foamy, but those who prefer a slightly firmer feel or want the ability to fine-tune firmness via inflation will likely prefer the MegaMat.
Compared to other self-inflating camping mats, Therm-a-Rest’s MondoKing 3D is thicker at 4.25 inches, but the Exped MegaMat Duo gets the edge with its availability in multiple double-wide sizes. Its vertical sidewalls maximize the usable surface area, and the soft tricot polyester top feels noticeably plush against bare skin. The nights I’ve spent on the MegaMat—whether at established campsites or tucked inside the back of a vehicle—are some of the best nights of sleep I’ve had outdoors.
Dimension-wise, the MegaMat Duo is offered in three sizes: Medium, Long-Wide-Plus, and Queen. We tested both the Medium Duo (41 x 72 in.) and the Long-Wide-Plus (52 x 77.6 in.), and while the Medium felt sufficiently roomy for two adults, the upgrade in size was appreciated for spreading out or accommodating a kid or dog. The Long-Wide-Plus in particular felt spacious without being overkill in smaller tents, and is a great middle ground for couples looking to maximize comfort without stepping up to the larger Queen.
With an R-value of 8.1, the Exped MegaMat Duo is among the warmest camping mattresses on the market and is fully four-season-ready. Only a couple of camping mattresses—like the Dometic Highrise 10 and Exped’s own DeepSleep—surpass it at R-value 9.0, and the real-world difference is negligible for nearly all conditions. We’ve used the MegaMat Duo in a wide range of environments, from damp 40- to 50-degree nights in Washington to dry summer conditions and even into the 20s on colder mountain trips. Across the board, it delivered. That dreaded feeling of cold creeping up from the ground simply never happened. For car campers who get cold easily or want year-round confidence, the MegaMat is about as good as it gets.
With a 75-denier polyester base and a 50-denier tricot top, the Exped MegaMat Duo offers strong durability. While the top fabric is a bit thinner than some competitors, it’s also softer to the touch and still holds up well to regular use. Build quality is excellent: the valves are high-end, the foam hasn’t packed out, and the materials are highly resistant to punctures and abrasion. One of our team members is still using a previous-generation MegaMat that has been in use for more than five years and is still going strong.
Compared to the rest of the camping mattress market, it stacks up well—similar to the Therm-a-Rest MondoKing 3D (also 75D and 50D) and notably tougher than Sea to Summit’s Comfort Deluxe, which uses a thinner 30-denier top. It can’t match the bombproof, all-foam Hest Foamy, but short of that, the MegaMat is one of the most confidence-inspiring designs we’ve tested. A repair kit is also included for peace of mind, though we’ve never had to use it.
The MegaMat Duo’s updated design has brought some meaningful improvements in ease of use, but a few quirks remain. Inflation and deflation are controlled by clearly labeled valves (one for inflating and two for deflating), which are intuitive and reliable. The second deflation valve is a welcome upgrade, noticeably reducing the effort required to fully empty the mattress—a significant advantage over older versions that necessitated multiple full-body roll-ups. Now, it’s often a single effort and a little quicker overall.
Exped also added a welded carry handle to the sidewall of the mat, which makes repositioning it around camp or in your tent a bit easier. It’s not something we used frequently—most of the hauling is still done in the included stuff sack—but it’s a nice, no-downside touch. Speaking of the stuff sack, it’s side-loading, oversized, and easy to pack even if your fold isn’t perfect. It also has its own carry handle, which makes for a practical and user-friendly storage solution.
The biggest drawback is the tiny pump sack that comes with the mattress. While the MegaMat mostly self-inflates, topping it off manually is painfully tedious with the included pump—it can take hundreds of pumps if you’re setting up quickly. At this price, we expected something more functional (purchasing Exped’s Mega Pump separately will set you back another $65 but makes life quite a bit simpler). Overall, the Exped MegaMat Duo is easier to manage than in years past, but the inflation process still leaves room for improvement.
The MegaMat Duo isn’t remotely compact or lightweight, but for the comfort it delivers, the tradeoff is more than reasonable. The medium version we tested weighs in at 7 pounds 5.8 ounces and packs down to a bulky 11 by 22 inches. If you opt for the largest queen size, those numbers climb to 11 pounds 14 ounces and a massive 12 by 31.5 inches. That’s big, even by car camping standards.
To be fair, this isn’t wildly out of line for a luxury camping mattress—Hest’s all-foam Foamy, for example, weighs over 11 pounds and doesn’t pack down nearly as small (it’s 30 by 12 in. for the “wide” single size). Still, the MegaMat Duo takes up a significant chunk of space in a small car trunk or roof box, especially when paired with a bulky tent, camp chairs, and cooler. On the other hand, if you’re driving a larger SUV or pickup, the packed size may not be an issue at all. For most campers, it’s a manageable compromise for one of the most comfortable mats on the market.

Longevity
Choosing durable outdoor gear and keeping it in use for longer is one of the best ways to reduce environmental impact. Our proprietary longevity rating assesses factors like overall build quality, materials, fabric denier, component durability, and real-world performance. A green check indicates that we expect the product to be long-lasting relative to its peers, a yellow check mark indicates average longevity, and a red X indicates a product that may have a limited lifespan.
Recycled Materials
Recycled materials are prevalent in outdoor gear, with nylon, polyester, wool, and down among the most common, but the composition varies widely. A green check mark indicates the product is made with a substantial amount of recycled materials (100% recycled or the core fabric that makes up most of the product is recycled), a yellow check means it contains a moderate to small amount of recycled materials, while a red X means there are no recycled materials in the product.
Bluesign Approved
Bluesign Technologies, based in Switzerland, operates a third-party textile management system that ensures materials are manufactured to strict environmental, chemical, and worker safety standards. A green check mark indicates a product is either a Bluesign Product (contains at least 90% Bluesign-approved fabrics and 20-30% Bluesign-approved accessories) or features a significant amount of Bluesign-approved materials. A yellow check mark means it uses some Bluesign-approved materials but less than the aforementioned category, and a red X means there are no Bluesign-approved materials in the product.
Repair Kit
Repair kits help extend a product’s lifespan by allowing users to quickly fix issues—like sleeping pad punctures or damaged inflation valve seals—rather than replace the item entirely. A green check indicates the product includes a repair kit, while a red X means it does not.
Responsible Manufacturing
This criterion evaluates a brand’s commitment to fair wages, safe working conditions, and reducing environmental impact through certifications and programs like Fair Trade Certified, Fair Wear Foundation, Worldwide Responsible Accredited Production (WRAP), and the Fair Labor Association, while also recognizing brands that manufacture primarily in the U.S. or Europe under strict labor and environmental regulations. A green check mark indicates a brand meets our responsible manufacturing criteria, while a red X means it does not.
Recycled and/or Reduced Packaging
Packaging can add significant waste to outdoor gear purchases, so many brands work to reduce its impact by using recycled materials, incorporating Forest Stewardship Council-certified paper products, and minimizing plastic and paper use. A green check mark indicates a brand uses recycled or reduced materials across all of its packaging, a yellow check indicates moderate or limited use of recycled or reduced packaging, and a red X indicates the brand does not make either of these efforts.
Repair Services
Repair services extend the lifespan of outdoor gear and reduce overall consumption, though programs vary widely. Some brands offer comprehensive repairs for a range of issues, while others provide limited or no repair support. A green check mark indicates a robust repair program, a yellow check mark indicates limited repair services, and a red X indicates the brand does not offer repair services.
Resale and/or Recycling Services
Resale and recycling programs help keep outdoor gear in circulation longer and out of landfills, ranging from trade-in resale platforms that offer store credit to take-back initiatives that recycle products at the end of their usable life. A green check mark indicates a brand offers both resale and recycling programs, a yellow check mark indicates it offers one or the two, and a red X indicates it offers neither.
Carbon Footprint Tracking
This criterion evaluates whether a brand measures, reports, and works to reduce its greenhouse gas emissions using established frameworks such as the Higg Index, Greenhouse Gas Protocol, or The Change Climate Project. A green check mark indicates a brand publicly reports greenhouse gas emissions data, sets clearly defined reduction targets, and uses established tracking frameworks such as Higg or The Change Climate Project. A yellow check mark indicates the brand tracks emissions and outlines reduction goals but provides limited data, lacks science-based verification, or does not clearly report progress. A red X indicates the brand does not appear to track greenhouse gas emissions or provides so little information that its efforts cannot be verified.
Annual Impact Report
Annual impact reports provide transparency and accountability by outlining a brand’s sustainability efforts across areas such as material sourcing, greenhouse gas emissions, waste, water use, supply chains, and packaging. A green check mark indicates a brand publishes a detailed, brand-specific impact report that closely aligns with our sustainability criteria and leaves little room for ambiguity. A yellow check indicates a brand provides some relevant sustainability reporting but lacks detail in key areas or is covered only briefly within a parent company report. A red X indicates a brand does not regularly publish an impact report.
Exped DeepSleep Duo ($280): Save Some Cash, Lose Some Comfort
If you want to take advantage of Exped’s design quality but don’t want to punish your bank account, the DeepSleep Duo is a viable alternative—although it comes with some caveats. This double pad is just as wide as the MegaMat Duo (41.3 in.) but only 3 inches thick, so side sleepers have a better chance of feeling the ground. Thankfully, the DeepSleep’s plush topper still makes for a comfortable experience, and we found its self-inflating design to be a bit quicker than the MegaMat’s. The DeepSleep has an R-value of 9 so it’s slightly warmer than its more expensive cousin, although in practice it’s hard to notice the difference in pads that toasty unless you’re camping in the Siberian winter. Finally, the DeepSleep only has one deflation valve, making it a bit less user-friendly than the MegaMat. Between that and its reduced thickness, you can see why it costs less. To learn more, check out our Exped DeepSleep review.
Nemo Quasar 3D Insulated Double Sleeping Pad ($280): Lighter, Wider, Less Luxe
If portability in a double-wide pad is high on your checklist, the Quasar 3D has you covered. At 3 pounds 6 ounces it’s less than half the weight of the MegaMat Duo, and—if you pack smartly and don’t mind carrying some bulk—you can even push into light backcountry duty. The Quasar’s 3.5-inch-thick air baffles are far less plush than the MegaMat’s open-cell foam, though, and its air pad design requires much more huffing and puffing. This lighter pad is also less durable, with 30-denier polyester construction that you’ll have to treat more carefully than the MegaMat’s fabric, and with a 3.3 R-value is only adequate for warm-weather adventures. However, at 52 inches across the Quasar has the MegaMat Duo beat for width, so it’s a good option if you want to spread out as much as possible without breaking the bank. For more, read our review of the Nemo Quasar 3D Insulated.
This double-wide pad is the ultimate sleep platform for outdoorsy couples or solo campers who want to max out their sleeping space. The MegaMat is plush, warm, and supportive, and the new version has some welcome design updates. If only it were less expensive and easier to inflate.

This trimmed-down version of Exped’s popular MegaMat is a little thinner, features firmer foam, and is much more affordable. The DeepSleep’s soft top fabric and high R-value are nice touches, but they can’t match the comfort of heftier pads.

The Quasar 3D Insulated is the only pad we tested that’s a true backpacking/car camping hybrid. It offers a healthy dose of durability and support (for an air pad, at least), although it’s not very warm and way less comfy than true car camping models.

It’s an oldie but undeniably a goodie: The latest version of the Exped MegaMat Duo remains one of the most comfortable two-person camping mattresses on the market. With 4 inches of plush cushioning, excellent warmth, and durable materials throughout, it delivers a near-bedlike experience that’s ideal for car camping in all four seasons. The packed size and setup process are bulkier and more tedious than some, but for campers who prioritize comfort and can handle the tradeoffs, the MegaMat Duo won’t let you down.
