Input:
I camped for the eclipse and arrived at my destination later than expected, so I had to basically throw a tent "somewhere" where I had space (in the dark). I didn't want to make a bunch of noise, either, so I used a foot bellows pump to inflate this thing. While it took several minutes, it was WAY less time than this method would have taken with a "typical" airbed.

This inflatable mattress survived a night on a very rocky surface (my tent floor, OTOH, was punctured in a couple of places - FWIW I am probably 180 lbs and I was by myself). It was certainly comfortable, though the end "pillow" was best with an actual pillow on top of it (at least for me). This was perfect size for my Coleman Pop-Up tent (where headroom is at an absolute premium, it is important that your air mattress is thin). It folds into a smaller space than a typical air bed, so it's more portable.

I would suggest you buy one of you need a bit of extra tent space, provided you are capable of getting up off of the ground. I'd also suggest having one if you're hiking for days/weeks (and want something better than a "pad"). This is much thinner overall than a typical air mattress, so if you do not put it on a cot or platform, prepare to "pick yourself up off of the ground"... but, to some people, that's not a bad thing.
