I have a largish quantity of 6.5cm thick memory foam , actually 2 lots
of 150 x90 cm., which I am happy to give to anyone who cares to collect
it. Having a layer of memory foam under and behind you is an effective
way of lessening the damage to you in the case of a hard or crash
landing. This comes from a NASA designed mattress just replaced by an
even more expensive mattress at the instigation of she who sleeps on the
other side of it! My cushions were made from 2.5 cm sheets of memory
foam, which then came in three colours corresponding to three degrees of
softness. This mattress foam I think corresponds to somewhere between
the medium and softest versions, and would make good extra cushions to
be available for small passengers
