I mostly carry my switchback, I had an ultralight inflatable, but it didn't hold up. I have an ancient 3/4 therma-rest guidelite that I carry some times in the summer, but it's half a pound heavier than my switchback. Mostly I just try to hike hard enough that I'm tired enough to sleep where ever. I agree with the poster who mentioned shelters, the switchback is way better on the ground than a shelter floor.
I have a thinner version of this and I can’t stress enough that it is self inflating!! Open the valve and let it sit to fill with air. Don’t put anything on it. Once full close the valve and set up everything. When folding and rolling away open valve get all the air out and close valve to seal. I have seen these where the owner would blow to fill it up and they get moldy and stinky fast. Also store it unrolled and open valve, I put mine under my bed.
We have therma rest inflatable backpacking mattresses (neoair and my 10+ year old pre-neo pad) , that we take car camping aswell. I often lay out more blankets on top, especially if we have my 4yo stepson with us. 3 pads, 2-3 layers of comfy blankets and then we can basically use sleaping bags as top covers, or individually, or whatever we feel like.. It might help though that while we cuddle/snuggle a lot, we don't generally touch each other that much while actually sleeping due to overheating. I can tolerate it more though, so I get stuck with kiddo near me haha.
We use Thermarests or their equivalent from like REI. ¾ sized ones to save some bulk.
I've had great success with Thermarest, REI, and Exped self inflating mattresses. All have good customer support too. I wouldn't ever bother with an all air mattress. Poor insulation, rotten in cold. Get a FlexTail pump.
Exped, REI, and Thermarest pads have all lasted that long and more. All self-inflaters.
My first winter camping trip is one I’ll never forget, my back was killing me after trying to sleep on a foam pad. The next trip, I brought a Therm-a-Rest Self-Inflating Pad and it literally changed everything. Suddenly, I was sleeping warm and supported, ready for morning hikes. I’d recommend [air mattresses](https://www.reddit.com/r/KeepThisInMind/comments/1ltzxk1/recommend_the_air_mattress_best_for_camping/) for camping to anyone, from lightweight backpacking pads to thick car-camping mats, especially for winter trips.
I've used a self-inflating Thermarest under a Big Agnes pad...half inflated
