My wife and I have P.O.E. max thermo 3/4 inflatable pads with synthetic insulation inside, 15 oz. each. Alone, they will get us down to the 30's then we add a 1/8" foam pad and then a 3/8" foam pad when planning for the teens. A 3/8" thick egg crate foam pad cut to 24" long is used under our legs always.
My wife uses a Montbell pillow and loves it. It's flat, baffled construction keeps her head on the pillow. She is short (5'2") so she puts the pillow on top of the inflatable pad and still has room for her torso on the pad.
I am 6'2" and need the pillow off the sleeping pad, so I need a thicker pillow (side sleeper). I use a P.O.E. pneumo Ltw (lightweight) dry bag to carry our quilt or sleeping bags in so, I inflate that for my pillow and tie a strip of cloth around the center to make it have a "bow-tie" look, to cradle my head. Dual use equipment, yeah baby!
As an earlier post stated, the Stevenson's D.A.M.s are touted in all forums as being the height of comfort, but at a price of both weight and the pocketbook. All-in-all, I am personally very happy with my setup as a nice compromise between comfort, weight and price.
BTW; At the time of my purchase of the sleeping pads, about 3 years ago, there were sporatic reports of leaks in B.A. inflatable pads, more than I was comfortable with. While their customer service was reported to be excellent, that wouldn't help me in the field, so I went with P.O.E. Recently, I haven't seen any negative comments about the B.A. pads, but then again, I haven't been actively researching either. Just FYI, I do have faith in B.A. as a good company as I just ordered a Seedhouse SL 3.
