Not all 'memory foams' are alike, in fact I am extremely dubious my memory foam mattress is any different to a regular foam mattress in any regard other than marketing. I think it's pretty unlikely the Aldi mattress has the viscoelastic properties desirable for increasing crashworthiness.

I think cutting costs by going with totally unknown foams is probably not fulfilling the intent of the MOSP directive even if it fulfills the lettering. It's a sore point for me though as I once hurt my back in a hard outlanding accident. The BGA has a nice overview which read a bit handwavey but has some very good citations backing it up at the bottom. https://members.gliding.co.uk/wp-content/uploads/sites/3/2015/04/Safety-Foam-ed2.pdf On Sat, Dec 16, 2017 at 9:36 AM, Greg Wilson <[email protected]> wrote: > Aldi have queen bed size piece of memory foam 50 mm thick on special for > $150 today. > > No idea if it’s dense enough for glider seats but could be a real bargain. > > Merry Xmas! > > > Greg Wilson > > > > > > > > _______________________________________________ > Aus-soaring mailing list > [email protected] > http://lists.base64.com.au/listinfo/aus-soaring > >
