Car camping comfort champ, but some side sleepers find it thin.

Big Agnes has been great here (most comfortable I have ever used). Though I have their old double version.
63 yr old M with bony hips. Just a few years ago I could honestly sleep all night on a 1" foam, but something changed when I hit 60. I tried various 4 inch inflatables. Best comfort I have found is Sea to Summit etherlite. Few extra ounces weight penalty but worth it, good sleep is everything. Also slept great on a fat Big Agnes but had bad luck 2 different outings with slow leaks. Actually slept best with a hammock rig, still use it occasionally - but the hammock, skeeter net, tarp, under quilt, and not having a tent to hang out in during poor weather kinda gets old.
Every Big Agnes pad I bought have had 2 recurring issues: they are cold in the temps they advertise as suitable and they leak after a year.
I bought a Nemo Tensor last summer, the non insulated version and it's the least slippery sleeping pad I've used. I wonder if there is a different top layer. The big agnes I used previously was so slippery it was like they did it on purpose.
I went from a Klymit to a Big Agnes. Night and day difference.
Any time I've tried a Big Agnes it's just felt like a pool floatie.
