I'd like to jump in here and ask a more general question about camping mattresses. I've never had one and am finding the variety a bit baffling, not to mention that some of them are rather expensive to my mind. But I need to get one by, well, Monday!
So I see three basic types:
Foam mats which simply unroll, like those which might be used for yoga, say. Cheap, light, pack small, but perhaps not too comfy?
Self-inflating mats of various lengths and thicknesses. Bit more expensive but still affordable, pack small but not as light as foam rolls. Claim to inflate automatically with an automagical valve
Inflatable ones you need to pump up.
As far as I'm aware these are all filled with air (where they are not solid foam) but now I hear of down-filled mats. And I see prices into three figures. Could someone give me a quick guide without salesman-spiel? TIA!
