I have been on the sleeping pad journey this year as well. I have the Nemo tensor alpine, sea to summit comfort plus, and the exped ul winter pad. All in long wide. I’m 6’5” 220# and all have been able to keep me off the ground sleeping on my side. I am still fiddling with pressures to get the most comfort, seems to be a fine line on all 3 to have enough pressure to keep me off the ground but not too much where the pad is too hard. I was really surprised with the sea to summit since it’s the thinnest, but I feel it is the most stable and most comfortable due to the waffle design and the 2 separate air chambers. You can blow the side closest to the ground hard then the side you lay on lower pressure for more comfort. The tensor is a close second. The exped just doesn’t feel as stable and I don’t care for the vertical ribs.
