i love my thermarest. i have had it for ages and will not be switching to anything else anytime soon.
they never really are on completely flat and hard surfaces like floor or picknic tables.. but i have slept on all kinds of stuff and my back hardly ever hurts and most of the time when it does, it is unrelated to the pad or sleeping location.Lying on this on the ground at the store was everything but comfortable
