That mat looks pretty good to me, and inflatable mats are cool to sleep on most of the year, because the air inside is at ambient temperature.
As a skinny side-sleeper I don't get on with the 50mm self-inflating mat I have. I also dislike lying on a stack of three roll mats more than one night.
I recently discovered hammocks and now own a hammock sleeping bag, Snugpak Cocoon. I can sleep in the hammock for a week without discomfort - this is unheard of! Anyway a hammock removes the need for a sleeping mat. Interestingly, it's the only time I sleep on my back.
