Sea-to-Summit Comfort Plus Insulated. It is a dual-chamber sleeping pad, so you can tune the bottom chamber to provide protection from the ground and top chamber to give you the right level of cushion. None of the other pads on the market can do this, including celebrated Therm-a-Rest and Exped offerings. Exped Megamat is still more comfortable, but it won't fit inside a kayak and weights a lot more. S2S Comfort Plus is the next best thing.
Check out the Sea to Summit Comfort Plus XL - it's literally designed for bigger folks. The dual air chambers prevent you from bottoming out when side sleeping (i'm also a side sleeper at 260lbs). Usually around $199 but goes on sale sometimes and packs down surprisingly small.

I'm pretty much exactly like you. Tried and DONT LIKE: Therm-a-Rest NeoAir Topo Luxe. It's thick! But the horizontal baffles suck for side sleepers. Sea to Summit Comfort Plus Insulated. Not thick enough. Hip pain. Noisy. The one I want to try next: Therm-a-Rest NeoLoft.
I have the non-ul version of that StS pad and I love it more than any other pad I’ve used in the last 20 years…
Imo yes. The Sea to Summit mats are incredibly comfortable with 4-6inches of foam. I have one that has a built in pillow that I use for my feet (helps blood flow at night after a shitty day with the infantry Joes) and bought a wider inflatable pillow for my head. Best part is both the mat and pillow deflate and fit inside the small front pockets of the ruck.
