IMHO.
Memory foam as used by NASA is not used as crash protection. Rather, it is used to provide comfort and prevent bed-sores. How on earth and in space is it going to protect astronauts in the event of an impact accident?

Subject: Re: [Aus-soaring] Cheap memory foam Postage was a killer though. It was $89 us to get a 1"x32" roll here. That might be OK if you are looking to make a single cushion, but when you start looking to make a few for a fleet, the price is astronomical. It becomes cheaper to buy memory foam from a local supplier. I'm not convinced by the confor craze. I have not seen a single bit of evidence that the "superior" shock absorption has any meaningful outcomes in a crash. I'm only looking at the extra cost of memory foam to meet MOSP part 3 On Sun, Dec 17, 2017 at 5:08 PM, DMcD <[email protected]> wrote: >>This is comparable to the foam cushions that we currently have.

IMHO, the best value memory foam is the so-called "factory overstock" from Dynamic Systems in the USA. They do a range of densities and sizes and the price is very reasonable compared with say Confor. The initial drop tests done in the UK appear to have been done with Dynafoam. Your mileage may vary as they say over there but the Aldi foam is about the same as the medium soft from Dynamic and fine for an upper layer but I doubt it would actually absorb much in the way of shock… and isn't that what you're using it for? You'd need a medium density foam for that. Dynamic Systems do ship to Australia.
