Our Take:
4.4/5
The Exped DeepSleep ($190) offers a firmer, more affordable alternative to premium mattresses like the brand’s legendary MegaMat. At 3 inches thick, it’s not quite as cushy—particularly for side sleepers—but the brushed polyester topper feels soft against the skin, and the vertical sidewalls give it a roomy, usable surface. With a dense foam feel, it trades plushness for support, which some campers may prefer. Factor in the $70 savings over the MegaMat and solid overall construction, and the DeepSleep stands out as a well-built, high-value choice in the premium camping mat space.

Pros

Attractive blend of price and Exped quality.
Durable material makes it unlikely to spring a leak.
Dense foam build might be a plus for sleepers who prefer a firm surface.

Cons

Rolling the pad up takes a bit of effort due to the foam core.
Self-inflating design only fills the pad about one-quarter full.

The Exped DeepSleep offers firm, supportive comfort at a more affordable price than many thicker, premium camping mattresses. I found that it molded well to my frame and gave ample room to toss and turn, making for a restful night’s sleep. The brushed polyester top has a soft, skin-friendly feel and stays quiet when you shift around. I tested the Long Wide version (77.6 x 25.6 in.), which provided enough space for my 6-foot-3-inch height and side-sleeping style, though the 25.6-inch width isn’t as roomy as 30-inch-wide alternatives like the REI Camp Dreamer or MegaMat LXW. Still, the rectangular shape and vertical sidewalls help maximize usable surface area.


At 3 inches thick, the DeepSleep doesn’t match the plushness of 4-inch pads like the MegaMat or Nemo Roamer, and side sleepers may want more cushioning under pressure points. But for back sleepers or those who prefer a firmer sleeping surface, it’s a great fit. Exped specifically calls out this intended use case, and it lined up with our experience in the field. While it may not offer the same memory-foam-like softness as top-tier designs, the Exped DeepSleep provides reliable comfort and support—and at $70 less than the same-sized MegaMat, it’s a standout value in the firm-and-functional category.

The dense foam construction of the Exped DeepSleep delivers serious insulation chops, making it one of the warmest camping mattresses on the market. With an R-value of 9.0—tied with the Dometic Highrise 10 for best in class—it offers true four-season performance. This level of warmth is overkill for most campers but provides excellent peace of mind for cold sleepers or those venturing out in sub-freezing temps. In my testing, I paired the DeepSleep with Exped’s MegaSleep Uno 25/40 bag and used it in conditions ranging from 30 to 60°F. Even on colder nights around freezing, the mat effectively blocked out the chill and kept me warm and comfortable.


You may never tap into the full insulating power of the Exped DeepSleep unless you’re camping on snow or in the teens, but its performance margin is a major strength. Compared to camping mattresses in the 6.0–8.0 R-value range like the Nemo Roamer or MegaMat, the DeepSleep is a better match for year-round use, particularly if you’re sensitive to cold or planning shoulder-season adventures. It’s a standout option in this category for anyone prioritizing warmth.

With a 75-denier polyester shell and TPU laminate on both sides, the Exped DeepSleep is among the sturdiest air-filled camping mattresses we’ve tested. The top fabric is notably thicker than most—including the 50-denier top on the MegaMat—which adds confidence when using it around pets, kids, or rugged ground. The valve system felt solid and sealed tightly throughout our testing, and a repair kit is included for peace of mind. While the all-foam Hest Foamy still leads the category in overall toughness, the DeepSleep is impressively durable and stands out as an excellent value for the quality of materials used.

The Exped DeepSleep’s setup process is straightforward and familiar: open the inflate valve and let the self-inflating foam do the work while you take care of other camp chores. It’s not fast, but after about 30 minutes you can top it off with the included pump sack. The sack doubles as a foot pump and works well for minor adjustments, though it’s inefficient for full inflation. That said, the DeepSleep’s smaller volume makes the process less tedious than bulkier pads like the MegaMat.


Packing up is equally hassle-free. The deflation valve dumps air quickly, and the foam core rolls more easily than thicker 4-inch pads (though not as easily as air-only designs). Integrated straps help keep it secure when packed, and while the top-loading stuff sack isn’t as convenient as a side-loading one, its generous dimensions make storage easy enough.

The Exped DeepSleep hits a nice middle ground between comfort and portability. The Long Wide version we tested weighs 4 pounds 14 ounces—lighter than many premium camping mattresses—and packs down to a relatively slender 26.4 by 7.9 inches. That smaller diameter makes it notably easier to store and transport, especially in vehicles where space is at a premium.


Compared to competitors, it holds up well: the Therm-a-Rest MondoKing is a bit lighter at 4 pounds 6 ounces but noticeably bulkier (26 x 10.3 in.), while the Exped MegaMat is heavier (5 lb.) and thicker when packed (26.4 x 8.7 in.). For campers who want a balance of plushness and packability, the DeepSleep is a compelling choice.

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.

Exped MegaMat ($240): How Much Will You Pay for Comfort?
The Exped MegaMat is a step up from the DeepSleep in both quality and price. This self-inflating model is 4 inches thick, and so it isolates users from the ground better than the DeepSleep—especially if they tend to sleep on their side. However, the DeepSleep’s foam is firmer, so it might appeal to campers who prefer that type of feel in a mattress. The MegaMat has a tricot polyester topper instead of the DeepSleep’s brushed polyester; both are plenty comfy, but you might prefer one to the other. Additionally, the MegaMat comes in at an 8.1 R-value compared to the DeepSleep’s 9.0, but you’ll probably never notice the difference in warmth. These pads also weigh pretty much the same, and your choice will probably come down to whether you think that extra inch of cushion is worth $70. For more, read our review of the Exped MegaMat Duo.


Sea to Summit Camp Plus ($99): A True Bargain-Bin Pick
Looking for an even more affordable pad? The Sea to Summit Camp Plus is a truly wallet-friendly option that offers decent comfort for under $100. You do lose some features that make the DeepSleep feel so pleasant to sleep on, though, including vertical sidewalls—the Camp Plus feels more like a backpacking pad—soft topper fabric, and four-season warmth (this pad’s R-value is 4.3). The Camp Plus is also 3 inches thick, though, so should still be comfortable enough for most back- or stomach-sleepers, and its 75-denier polyester fabric will most likely prove just as durable as the DeepSleep’s. It’s also about half the weight (it’s 2 lb. 11 oz. its rectangular wide version) so can lug it short distances into the backcountry if you really want to. Mostly, though, this pad is good for campers sticking to a tight budget or who want an extra mat lying around for friends. For more, read our Sea to Summit Camp Plus review.

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.

Exped MegaMat Duo ($450)

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.

The Camp Plus blurs the line between a backpacking pad and a car camping mat, but its value as a true budget option is laser-focused. While it doesn’t provide the comfort of other models we tested, this is a relatively light three-season pad that will suit occasional campers just fine.

Is the Exped DeepSleep for You?

The Exped DeepSleep is a strong value pick for campers who want high performance without the premium price tag. It doesn’t have the plushest or widest build, but its firm support, excellent warmth (with a top-tier R-value of 9.0), and durable materials make it a dependable companion for cold nights and long weekends. Side sleepers or those who want maximum cushion may prefer a thicker 4-inch camping mat like the MegaMat, but if you’re a back sleeper or don’t mind a firmer feel, the DeepSleep is a well-rounded and cost-effective choice.
