impressive comfort for something so small,
This review is from: Vango Trek Self Inflating Mat (Sports)
I bought one of these recently to replace an inflatable bed, and found it to be deceptively comfortable used on a ground sheet on relatively flat terrain. Basically, you unscrew the stopper and the sponge filling fills up with air and then you close the stopper again. To put it away, unscrew the stopper and roll it up. Comes with a stuff sack which it fits into without a wrestling match(hooray!).
My advice is to buy the longest version of this that you can.
