I've previously used one of the OzTrail Self Inflating Leisure Mats for about 6 months or so as my nightly main bed, in their Double size.
I'm a notoriously light sleeper and have found it decent enough. In theory, it's easy to roll up 'compact' with the one way air valves, and 'leak proof' with the internal foam.
In reality, it's not without issues though:
Its a non-laminated cover so if you do up the air valves and both hop on, tend to 'puff' up around you. Solution - leave the valves open. Worth noting it's not a firm mattress (which I normally prefer) and this only makes it softer, but will keep you off the ground easily and is still probably comfortable enough ( would recommend in-store test first tho).
It rolls up massive. Think almost swag-size (40cm+ diam) if you just try to roll-and-go. The newer model one-way valves allow you to make several attempts with rolling more air out, but this takes time and ALSO tend to shift the non-laminated poly skin out of alignment with the foam inner, which then move the air valves away from the channels in the foam and slows re-inflation.
Solution - deflate with a pump or in my case, a small hand vacuum. Doesn't need any special valves or adapters, just a tube mouth roughly the same valve diameter. Hold it in place and suck the air out until flat, then roll. Works like a charm and get the roll down to about 20cm diameter.
Not perfect but good enough that I'v just bought this -

They also have larger "King" singles too
