I am the same way, when I do camping for a while I like to be able to sit and rest my back. I have been using that exact Trekker chair for a while (even the same color) and I absolutely LOVE it. There is no way I would go on a trip without one, even on a weekend trip. It is so light anyway. I don't use it right on the ground though, I saw people doing it but I try to take good care of my pad (they are pretty expensive!). Anyway, yes it does suppot your back, I was skeptical about it, but I went on a trip with a friend who had one, I tried it and I was hooked! I actually stopped to the first REI and bought one, so we both had one to finish the trip! Anyway, go for it you won't be disapointed.
