I imagine many new campers inflate a pad until it feels rigid, lay on it, and decide that it's not comfortable. Adjusting the air level is critical to comfort, as is a pillow that works for your style of sleeping. If I over-inflate my large, older TR camp pad (I think it's called the Luxury something now) it's marginally more comfortable than lying on a 1/2" blue CCF pad. Dialing in my Neo-Air produces sleep for me near as well as the large air-over-foam pad. To further OM's analogy to shoe fit, dialing in a pad with inflation level and pillow is akin to the proper insole for your feet in said footwear.
