Nadia, there is no way that an oil will do what nuru gel does, however I've not tried thick differential oil yet :))
It's the thickness of the layer, the gel easily the thickest my a royal margin, which causes friction to be almost negligible. Once you feel it you'll have not doubt anymore.
I've had a nuru massage in a tarpaulin hung in a (tiled) room, strung very tight so the sagging was minimal, just enough to prevent excessive spilling. An air-mattress won't do too well, but I think that a small trampoline will do best, and is cheap enough.
Nuru gel washes off easily with some soapy water, but I'd hate to clean all when oil is used... probably a steamcleaner would be needed? ;-)
