This pad is great and a 'second bed' with sleeping bag, when visiting distant places on overnight casual activist/protest assemblies. It could work outside, I guess. I have not had the opportunity to test it on the ground.
I was unhappy with the ease of puncture of the self inflating 'bubble' nature of its design. (The dual valve closure and the self inflating design is top quality.) If the bed lost the integrity due air containment the air mattress inner foam pad failed to hold the user's weight off hardwood floors. Zero sleeping comfort. I had to search for glue on patches. The usual patch kits were too small for my large blunder-tear. Eventually, I found patching ‘glue-on’ that sufficed.
Now I am pleased but the rip stop toughness of the outer air mattress bubble failed to elicit 5 star rating from my perspective.
