Rated 5 out of 5 by from compact, light, comfortable, durable I've been backpacking for years and I've always used a thermarest z-lite, but I finally decided to be more comfortable and give an inflatable air mattress a try. I decided on this because it seemed like a nice combination of light weight yet durable, and good for 3 seasons (and 4 with the z-lite). I love how there are dual chambers so if I get a puncture there will still be something to sleep on. So far it is much more comfortable than the Z-lite and feels durable. it is much quicker to inflate than an I expected, and it deflates instantly. Its very compact. After a few times out in the backcountry, i'm happy!

Rated 5 out of 5 by from Lightweight, warm, comfortable sleeping pad This is an amazing sleeping pad. It is incredibly small and lightweight to carry. Yet inflates to full size that is long and wide enough to fit my entire body in any position. It inflates very easily (I inflated it myself, without the use of a pump). I am very tall, and boney, and angular, and I crave comfort and warmth the older I get. This pad was very comfortable. I used it on a 3 day hut trip. I let all the other adults try it out one evening. Every one of them said that it was very comfortable, particularly when lying on one side or the other. I slept outside on the deck, in freezing conditions, at 11,000 ft, and I was very comfortable. It did a great job insulating me from the cold ground, as well as keeping me comfortable in all positions.

Rated 5 out of 5 by from Great Lightweight Pad I used this pad on a recent three night backpacking trip through the San Rafael Wilderness and had a great night's sleep every night. It didn't crinkle or squeak like other inflatable mattresses that I've used over the years and it and was easy to inflate in less than a dozen breaths. I was also very impressed at how fast it deflates and how small it compresses into its storage sack. If you are a side sleeper or have had trouble finding the right mattress, this is your pad!

Rated 5 out of 5 by from Light weight - but deflated measurement misleading REI was great. I got the sleeping mat and measure it flat as it seemed way too long for a small (79 inches and small 66). So I called and they shipped me another one right away. I thought the wrong one had been put in the packaging. The next one I got was just as long so I went to a nearby outdoor store and measured - still long. I was perplexed so called Sea to Summit and they said the inflated length would be shorter. Sure enough it was. Just an FYI as I thought the packaging and the markings on the mat were wrong. REI provided great customer service!

Rated 5 out of 5 by from Testing of a Sea To Summit pad I've had a backpacking sleeping mat that has served me for 6 or 7 years. It's an REI Trekker, insulated (R 2.5 I believe) kids' pad. I originally went for the kids' version because I wanted to shave both weight and volume, but it's shorter than me and it meant that my feet and calves were always off the mat. Comfort was secondary. I'm 5' 4" and weigh 145 lbs, by the way. The other day, when we started planning our backpacking trips for this Summer, a friend of mine pointed out that he had a Sea To Summit air mattress that packed small and light and had good insulating properties for Summer adventures. I had never considered an air mattress before, I really don't know why (maybe because I thought they were less durable, but I have no data on such a statement!). My friend offered to lend it to me so that I could give it a try before committing to a purchase. So I went ahead and I set up the two mats (my REI Trekker and the Sea To Summit Comfort Light mat) in my living room for a couple of days. The Sea To Summit mattress was about 2-3 times thicker than my REI Trekker, which made it significantly more comfortable, especially when lying on my side (this is how I usually sleep). There was no "slushing" of air around, so at no point did I feel the hard floor beneath me, regardless of how I lay on it. Did I mention it's really comfortable? It was the Regular size, so it was a full length mattress. This meant that my feet and legs were not dangling off the bottom. Yet when packed, the Sea To Summit mattress was still a lot smaller than my kids' version of the REI Trekker. Albeit not self-inflating, the Sea To Summit mattress is very easy to inflate, and kept the air inside during my living-room tests with no obvious deflation. It was also easy to deflate and faster to roll up than the REI Trekker. I can't speak to its insulating properties because I compared them in an indoor setting. However, I only do backpacking trips in the Summer, when the ground is not as cold and insulation is less of an issue. All in all, I've decided to invest into a Sea To Summit Comfort Light pad, so that I can get more comfort and better sleep without adding weight or volume to my backpack. I will try to post another review after our first backpacking trip. I'm really looking forward to a good night's sleep in the wilderness!
