Biphasic Sleeping Mat

 Inflatable sleeping mat for the hills

Sleeping mats come in a number of different configurations, but rarely are any suited for the actual ground you lay on, which is normally angled at some degree. What to do?

The Biphasic Sleeping Mat is built of two air chambers; imagine two thin wedges, stacked oppositely on each other to create the thick rectangular sleeping mat we would normally expect.

Simplly letting the air out of one wedge would incline the entire deal and give you a better sleeping experience.

(These come in horizontally and vertically biphasic variants.)

       + for the idea process, but think the tapering shapes will be hard to retain without some built in rigidity.

       That's expected; all sleeping mats currently do this already to keep flat and not become a sphere.

       How about lots of independently inflatable chambers below the pad? Not only for dealing with inclines but also uneven ground surfaces. The pad itself could have an array of electronics arrayed throughout to ensure each chamber is inflated to the exact amount needed for an even sleeping surface.

       Trying to keep it mechanically simple.   

       Just thinking again about what xen said, I was assuming the mats would be similar to the 'self inflating' mats which are filled with a foam glued to either side, providing that sort of structural rigidity. (see link)

       A self inflating mat sounds terrifying. I don't want myself inflated.

       The device would end up forming a curve, with the deflated thin part being lowest. It sounds very uncomfortable. [-] A version with a dozen cells could accomplish this, but it sounds pretty baked to me.

       Admirable modesty.
