I use a Sea to Summit Camp Plus sleeping pad. It's only 1.5" thick, which means unlike some of the Expeds and similar brands, it'll actually pack fairly small (not small enough for backpacking) and not take up half your car. As long as you don't need a super strong R value and are doing 3 season, I think it's hard to beat.
Oh you're right, I have the regular Camp, not the plus.
I use a Sea to Summit sleeping pad. It's only 1.5" thick, but it holds air so I still don't feel the ground regardless. It works perfect with folding rear side seat down in a Tesla Model Y
It's a Qomotop, but I don't see them for sale anymore. Really, just look for any self-inflating pad, then look at reviews. The valve on mine looks like this one, which is a Forest Dawn on Amazon. Sea to Summit seems to have some good prices now. Mine is 4 inches thick. https://preview.redd.it/4yybdcuyugef1.jpeg?width=829&format=pjpg&auto=webp&s=543cb29673b12eb77528047244ced74433ba6de5
I just bought a used Sea to Summit of Poshmark for $25. Had a small leak that was easy to fix. Just set it up in the house and seems really comfortable. Packs up small
I used a Therm-a-rest in 1994 and, more than 30 years later, I don't see any reason to choose something else. I stopped using those for backpacking trips in favor of ultralight inflatable sleeping pads (which you DO NOT inflate with an electronic pump) because they are so much lighter, but for something like drum corps where you are using it every day and you aren't carrying it in a pack up a mountain, it's Therm-a-rest (or similar self-inflating pad from many other brands, e.g. Sea to Summit) all the way. They are more comfortable than a close-cell foam pad, still lightweight, relatively durable, and you won't have to be screwing around with a pump when you just want to be sleeping after a 3 AM bus arrival.
I’m 36 y/o. I dunno what happened. Maybe my sleeping pad sucks ass? Maybe I’m out of shape? Maybe I’m not tired enough? Maybe it’s inevitable? If there are any tips, please lmk. It sucks to see something I love start to be something I don’t care for anymore. Or maybe I can still love it but just be in a cabin? Edit: I’ve got a Sea to Summit Camp mat S.I. and my Fiancé’s got an R.E.I. Trailbreak. Hers is more comfortable than mine but neither are comfortable enough to not be tossing and turning all night. Also, both seem to deflate if I sleep on my side. And I don’t see any air holes in either. I’m 5’7” and 184lbs and she’s 5’4” and 180lbs.
We use fold up carton type mats as our base. Then in our tent we have Sea to Summit self-inflating bed rolls. Our kids have the same base and use Therm-o-rest self-inflating ground mats. We find as long as we stay on the self-inflating mats, we’re pretty comfortable. The ther-o-rests are almost 20 years old and still in great shape. We upgraded to Sea to Summit because they fold up so small for backpacking
