Our Take:
3.9/5
The Sea to Summit Camp Plus ($99) is a well-built budget mat that delivers solid value for car campers who don’t need maximum plushness. At 3 inches thick with tapered edges, it falls short of premium pads in comfort, but it’s impressively durable and easy to carry and store. You wouldn’t want to haul it into the backcountry, but it blurs the line just enough for short walks from the car. For budget-minded campers, it’s a thoughtfully built and reliable option that comes in about half the cost of top-tier competitors.

Pros

Burly 75-denier polyester material keeps pace with category leaders.
Light enough for pushing into backcountry duty.
Pillow lock system is a nice touch.

Cons

Thinner and less soft than many other car camping mats.
Single inflation/deflation valve can be a nuisance.
Thickness and R-value match the low price.

The Sea to Summit Camp Plus is functional but basic when it comes to comfort. Its 3-inch thickness is noticeably less plush than the 4-inch designs that dominate the premium car camping mattress market—including Sea to Summit’s own Comfort Deluxe—and the lack of vertical sidewalls means the surface tapers at the edges, reducing usable sleep space. On the plus side, the polyester face fabric is soft to the touch, and it’s a quiet mattress with minimal noise as you shift in the night.


I tested the rectangular wide version (72 x 25 in.), which matched well for my 5'5" frame and offered more room than my usual backpacking setup. That said, the cushioning felt like the bare minimum for true car camping comfort. The Sea to Summit Camp Plus is firmer and less supportive than thicker foam designs like the Exped MegaMat or Therm-a-Rest MondoKing, and it’s not a great option for side sleepers or uneven terrain. For back sleepers, occasional use, or those who aren’t particular about their sleep setup, it can suffice—especially given the lower price. The integrated Pillow Lock system is a nice touch at this tier, but overall, comfort takes a back seat here.

With an R-value of 4.3, the Camp Plus is squarely in the three-season category and falls short of more premium camping mattresses when it comes to insulation. For comparison, Sea to Summit’s own Comfort Deluxe comes in at an R-value of 6.6, while top performers like the Exped MegaMat and Therm-a-Rest MondoKing push even higher at 7+. In practice, I used the Camp Plus on a Thanksgiving trip in eastern Washington, where nighttime temps dipped into the 20s. While I stayed warm enough with extra blankets layered beneath me, I could definitely feel the cold seeping up from the ground. This mat is best suited for summer and mild shoulder-season camping with overnight lows no colder than approximately the mid-30s. Cold sleepers or winter campers should look elsewhere.

The Camp Plus is a standout in terms of durability, especially for the price. Its 75-denier polyester shell is among the thickest we’ve seen in this category, and the tough build inspires confidence for use around pets, kids, and rough campsites. Sea to Summit also includes a repair kit with three pieces of tape and a silicone adhesive tube—a nice touch for peace of mind. The single inflate/deflate valve isn’t our favorite in terms of ease of use, but it functions reliably and showed no signs of leaking. Only the all-foam, airless Hest Foamy scores higher in this category, but among self-inflating mats, the Camp Plus punches well above its weight.

The Sea to Summit Camp Plus is serviceable in setup and pack-up, but it’s a bit more finicky than most self-inflating camping mattresses. Its single valve is designed for both inflation and deflation, which simplifies the design but can be frustrating in practice—it’s easy to accidentally open the full-release mode when you’re just trying to fine-tune air release. Self-inflation only got the mat about 15% of the way there, requiring manual inflation to reach a usable firmness. On the plus side, the included stuff sack is generously sized and easy to pack, which isn’t always the case in this category. Overall, dedicated inflate and deflate valves and an included pump sack would improve usability, but the tradeoffs are understandable at this budget-friendly price.

At just 2 pounds 11 ounces for the rectangular wide version, the Camp Plus is one of the lightest camping mattresses we tested. Its packed size of 13.4 x 8 inches is impressively compact, especially compared to many thicker and more luxurious alternatives. For instance, the Therm-a-Rest MondoKing weighs 4 pounds 6 ounces and packs to 26 x 10.3 inches, while the budget-oriented Coleman Silver Springs is 5 pounds and significantly larger at 22.4 x 6.3 inches. Even Therm-a-Rest’s relatively light LuxuryMap checks in at 3 pounds 4 ounces and packs longer at 21 inches. For campers prioritizing portability, trunk space, or ease of storage—especially for kids or minimalist setups—the Camp Plus delivers standout convenience.

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.

Coleman Silver Springs ($70): The OG Budget Pad
Thanks to a build that’s even more bare-bones than the Camp Plus, the Coleman Silver Springs takes home the “Most Wallet-Friendly Pad” award. It’s a tried-and-tested workhorse that’s also built with 75-denier polyester, although the Silver Springs’ fabric feels far more plasticky than the Camp Plus’ material. It’s 3 inches thick as well, but we found that it feels thinner and so isn’t the pad for side-sleepers or folks who are camping on uneven ground. However, the Silver Springs has a praiseworthy 5.0 R-value that plays well in shoulder season, and its self-inflating, single-valve design does a good job of blowing the pad up in about 10 minutes while needing only a few top-up puffs. No stuff sack and no pump sack are understandable given the fantastic price, but we’d gladly pay more for the Camp Plus’ superior sleep experience and wider variety of sizes. For more, check out our review of the Coleman Silver Springs.

Exped DeepSleep ($170): More Expensive, but Still Good Value
The Exped DeepSleep costs almost twice as much as the Camp Plus, but within the blue-blood car camping pad category, this is still a great buy considering its feature set. Sea to Summit designed the DeepSleep with vertical sidewalls, so though it has the same 3-inch thickness as the Camp Plus, it’s far more cushioned and stable. The self-inflating DeepSleep’s foam is on the firmer side, so it should appeal to side-sleepers and campers who prefer more support, and its soft topper is an upgrade over the Camp Plus’ more raw polyester (it’s still a durable 75D, though). We have reservations about the DeepSleep being difficult to pack away due to its firm foam, and its R-value of 9.0 is probably overkill, even though it’s nice to have a true four-season model compared to the three-season Camp Plus. This is a better pad, but you’ll pay for the privilege. For more, read our review of the Exped DeepSleep.

3.9/5

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.

The standout quality of this throwback pad is its fantastic price, but the Silver Springs is not a good option for campers who seek even moderate comfort. At least it’s warm and durable enough to last until you get more into camping and decide to buy a better pad.

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.

Is the Camp Plus for You?

Sea to Summit’s Camp Plus offers a solid balance of packability, durability, and price—but with real trade-offs in comfort and warmth. Its 3-inch build and tapered sides fall short of the plush, bedlike feel you get with thicker, premium camping mattresses, and the R-value of 4.3 limits it to mild-weather use. That said, it’s light, tough, easy to store, and comes in at a fraction of the cost of high-end options. If you’re an occasional camper, not too finicky about your sleep setup, or simply looking to save, the Camp Plus is a budget-friendly option worth considering.
