I have a 30 inch NeoAir. It's actually the new NeoAir Dream for car camping, but inside it is the 30 inch NeoAir Camper model that can be used by itself for backpacking. It has two different packing options -- folded in half for a skinny 15 inch "bedroll" configuration or folded in thirds for a thicker short package. Both are easy to manage and fairly light at just over 2 pounds.
Super comfortable. Especially the Dream configuration, which also provides a ton of protection to the mattress.
I didn't think switching the Dream to the NeoAir made sense -- why bother for a car camping product. But, I've completely changed my mind. It's two products: the best car camping mattress ever and a fantastic backpacking mattress.
