I've stayed away from the inflatable beds because I've just seen so many that get punctured or leak on various camping trips over the years. And then you're truly sleeping on the ground.
The trick is to be careful where you unpack it and repack it. I've seen quite a few of my fellow campers develop leaks on trips. Invariably it was because they tried to inflate or deflate it outside the tent, where small pointy objects could be found. My process is to only unroll and inflate the mattress when it's in the tent. Same for deflating and packing. Never had one go flat just following that simple rule.
