When I was in my fourties I could not do this anymore, because I just could not sleep and my back would hurt for days. I bought a 1.5 inch Thermarest, which was better, but not as good as I hoped. I then bought a 5 cm Thermarest self inflating, which was a bit better again, but also bulkier and heavier. A few years ago I bought a 7 cm Exped Downmat, which was way more comfortable, and insulated much better. The Synmat UL is as comfortable as the Downmat, but only about half the weight, and packs far more compactly. I have just been on a rough tour with some contemporaries, and everyone used an Exped insulated air mattress or a Neoair. For maximum comfort, there are also 9 cm Exped mattresses.

I can not tell if this is about mats for people with bad backs or just getting a comfortable night's sleep.
