Big Agnes - Divide / Air Core Ultra Series

Be wary of uninsulated air mattresses in mild temps.  I bought 2x Big Agnes insulated pads for my twins, along with the BA kid’s sleeping bags for our twins. This is more of a backpacking setup, but works great for car camping and living room camping.  The bags have a sleeve on the bottom so you can slide the pad inside. Helps keep them in the bag and on the pad - again - cause the cold ground can give them a chill. 

Might be an issue specific to the pad or your back. We can be pretty particular when it comes to sleep, and it can take a few tries to really dial it in. I have a big Agnes air core pad. I don't think it's warm enough for winter camping but I've been comfortable laying on my back on it. I do usually side sleep, but I wake up on my back often and sometimes just lay on it to relax at the end of the day.

Big Agnes is the best I’ve found. Pricey but well worth it.

Have you considered a camping cot? There are a lot of ultralight options now which are about the same price as a good sleeping pad for side sleepers. The only difference being is the weight, you’re looking at around 1.5kg for a cot bed which would be double the weight of a sleeping pad. For me, the extra weight is worth it for the comfort. For context I’ve tried Therm-a-Rest, Big Agnes and Nemo mats. If I’m going for comfort, the cot bed wins every time.

Big Agnes pads are some of the toughest out there as far as I can know, yet I have gone through three because of punctures. Each time the holes have been so small that I can't find them without getting to a hotel and submerging them in the tub. The company is great about replacing them, but I've gone back to foam mats.

My Big Agnes Divide works for me, and I'm a side sleeper.

Big Agnes and sea to summit checks all your boxes. Small/compact, uses vertical baffles to prevent that bouncy castle feeling and provide actual support

It's very simple if it blows up with air and inflates - at SOME point it's gonna get a hole in it. That's life! The whole air mattress thing started with Therm-a-rest's and they were pretty tough back then, now with everybody sporting hard-on's for "ultralight" gear its gonna get worse. Same goes for actual air mattress, you can sleep on them but if you're not in Texas or Arizona yer still gonna freeze your butt off. Here's why ....... People these days buy inflatable pads for the comfort, but you really need them for the insulative qualities they actually provide. Don't believe me go sleep on the actual ground one night. When you crawl in to your sleeping bag you actually crush the down or syntho fill in the bag so there is no insulation there under you and the cold even in summer can seep right in. You need a pad under you to keep you off the ground ..... the best ones for that are still the cheap blue ensolite foamy's you buy at the cheaper stores but yes, for comfort they suck. There is a yellow thicker brand called Zotefoams Evazote and they got up to an inch thick but I haven't seem them for years but they were good quality and tough and CAN'T deflate ! So ultimately if you want comfort you need to go buy a big chunk of open cell white foam four inches thick and 7 feet long like you see in hobby stores - mega comfy and the size of a house! But now you can't pack it anyway so you're back to the blow up pads - and that's it. You can go to stores and look at stuff like Futons and crap but they don't pack well ! Heck even Ikea makes a folding mattress but again good luck carrying it around, right? Pick one but they WILL get a hole in them at some point however you can try to limit that with a cot. I've used them for years and its nice. I'm gonna suggest a Cabella's Lounger Cot but they are $350 bloody bucks and the same goes a real camping pad, something like a Exped Megamat itself is $400 bucks by itself. The two cots I wanna get are gonna cost me $405 bucks so add in two decent pads like Expeds and they're $500 .... great huh? It's nuts at a thousand bucks! I actually might just go get some memory foam cut at an RV store and use that. They can't deflate and its about the same bloody price as these inflatable ones, granted it won't be near as packable and portable but both my Thermarest leak, both my Big Agnes pad leak, even the TWO Coleman air beds leak, you can't win. My tent is 210 sq feet and 10 feet tall so I don't need backpack-ability either ........

I went from a Klymit to a Big Agnes. Night and day difference. 

Plus one. I have a therm-a-rest Xtherm, two cheap Amazon pads (they didn’t last), a Big Agnes, and I’ve tried the foam pads (they’re not for me). Exped seems to have the best tech. Their pads are quiet, comfy, reliable, and I love the synthetic down on the inside
