Why We Like the Comfort Deluxe SI Sleeping Pad

Ultralight pads might be great for backpacking, but when we're car camping why not have a little more cush under the tush? The Comfort Deluxe SI Sleeping Pad offers four inches of luxurious foam for sound sleep, while the self-inflating design means you can save your breath for the campfire.

Great choice for roof top tent

[This review was collected as part of a promotion.] We bought this for our Naturnest Polaris Plus Triangle Rooftop tent. The sleeping pad that comes with it is so thin and uncomfortable. I tried adding a 3 inch foam pad and my Klymit sleeping pads trying to make it somewhat comfortable to sleep on. That ended in tossing and turning all night because my hips and back hurt. So I started searching for a better option and saw a review for this sleeping pad and thought well why not. . . . well I can say we have been very happy with our purchase. We have a tendency to get to camp late in the evening so we used our airpump to inflate the mattress, putting to much air in it will cause it to be very firm especially with two people on it. Since then I have learned to keep it "squishy" if we have a late night setup. Otherwise if you can let it "naturally" air up with the two one-way valves on each side on the end, it is just about perfect. It fits the tent really well and inflates to a nice 4 inches of comfort. At the end of our trip we use the air pump to remove all the air out of the mattress so we can leave it in the tent for storage. Now that we have used it a few times there are a few things that would make it perfect. . . . (1) Having dual chambers for each side so you can adjust the amount of air for each person. I like it a little more squishy (Im around 170) but my husband (he is around 250) ends up feeling the bottom of the tent and wakes up sore. Letting it air up naturally, he finds it super comfortable and for me it is a little firm so I wake up a little sore (2) Move the air ports more to the middle so they are easier to access. The pictures are after we took our sleeping bags off getting ready to pack up and the wrinkly one is after I used the air pump to get the air out.

Sleeping pad

[This review was collected as part of a promotion.] I bought this to replace the same pad I bought 10 years earlier. It developed a small leak. Is it under a lifetime warranty?

Best Sleep Ever!

[This review was collected as part of a promotion.] This inflatable mattress has changed my car camping experience! Very comfortable. Feels like it is made of foam, not inflated. Best sleep ever in a tent! Easily inflates and deflates. Only negative is that it is large when rolled up. Oh and the instructions say to store it inflated, which is not an easy form for storage due to space limitations.

Great Car Camping Matress

[This review was collected as part of a promotion.] Comfortable “transportable” mattress, great for car camping. When laid out will start a process of inflating, then just top off with a pump.

Comfort Deluxe Self Inflating Mat

[This review was collected as part of a promotion.] This is by far the best mat I've used for camping, it's honestly as comfy as my bed. Buying top quality gear is always best. Companies like Sea to Summit back their products and that's why I will continue to buy their products. I was just hoping for a repair on my damaged mat, but they replaced it. That is a solid business. Thank you very much. I share this experience quite often.

Comfort Deluxe Self-Inflating Sleeping Mat

[This review was collected as part of a promotion.] We use these in our Class B+ RV. They are easy to inflate/deflate and we slip them behind the couch to store. There is no comparison to the comfort and ease of use for sleeping pads. Sea to Summit stands behind their products. We had an issue after 6 years and replacement was sent immediately! Couldn’t be happier with the product and company!

Best Camping Mattress!

Familiarity:
I've used it several times
Size Bought:
Double
Height:
5' 6"
Weight:
135

Purchased this mattress after much research and decided to order it. First camping trip was in May in the mountains of Nevada. I’m new to camping and this was super easy to inflate and set up. I love that I didn’t need a pump. Just set it up and let it self inflate. I did that first thing and by the time I’m ready for bed later it’s all good to go. I love how comfortable it is and doesn’t deflate at all over night. I went camping again in Mount Laguna, CA in July for the second test run with this mattress. Slept really good again and the set up was easy. I also love the bag it comes with to store it in and travel with. Protects it very well and easy to roll up. Camped again shortly after in Big Bear, CA. Seriously can’t imagine not having this mattress now. It’s worth every penny! I would buy it again and highly recommend.

Awesome

[This review was collected as part of a promotion.] Purchased two of these in the early summer to prepare for a two week long camping trip with my wife and daughter. First used in dinosaur national monument along the green river. Was around 103 degrees during the day 85 at night. Easy to set and durable. Extremely comfortable, didn’t sweat at night everyone slept great! Then moved up to Gros venture along the Tetons. Temp during the day was around 83 night lows were in the mid 40s. We used fleece thermal liners paired with the tanami down blankets. The sleeping mats helped us stay warm paired with other excellent products we got from sea to summit. Everyone loves them and we will be returning customers to see what else sea to summit comes up with in the future.

Best Sleep!

This is truly the most comfortable sleep you'll get outside. Absolutely recommend. In fact, I tell people about it because so many people say they don't camp because they can't 'sleep on the ground'. This pad is a game changer for that. The pad self inflates for the most part.. I end up putting a few breaths of air in to get to my preferred firmness. It is ridiculously comfortable. I camp primarily in Florida, so I can't comment on R value or warmth. I also camp from my car, so lugging it around isn't a big deal.. but it is bigger than both my tent and sleeping bag. But again.. not a problem in you have the space.. well worth it! I am 5' 5 1/2" and I got the regular, if I were much taller I'd recommend the longer version. Just for comfort.. if you have the space in your car.. why not? I also want to get the double.. because I had to inflate the ole air mattress this weekend after becoming adjusted to the insane comfort of the Sea to Summit pad.. and dang.. the air mattress is only half as comfortable as the Sea to Summit! And I used to like the air mattress. I'm completely spoiled with my camping sleep setup thanks to Sea to Summit
