Sure thing Trev,
I do not know much about new light weight inflatables, I only know the Neo Air and the (not so light) exped mats. These designs can ofcourse be used with such mats as well but is more intended for the standard self inflatables. If such tubed mats as Neo Air and Exped indeed get punctured or deflated you have no construction anymore
A standard self inflatable keeps it form when punctured or deflated, not that sturdy though so you'll lie actualy on the ground but sturdy enough to keep the form of the cot (as long as you use light weight poles).
But I even bet these constructions even work with 10mm to 18mm, in two or three parts cut-up, closed cell foam mats
Standard self inflatables don't get that quickly punctured if you only watch carefully were you place your tent (otherwise you could get a punctured tentfloor as well) and don't use it as picknick pad on the bare floor.
If you are really afraid of punctures some additional poles to keep the head and or footend upright can be added as well.
