Since you're so impressed, perhaps you would be happy to answer a
long-standing query I have with regard to memory foam mattresses?

Although it can be demonstrated that they do 'remember', say, the
pressure of a hand (as in the advertising), how do we know they're
remembering a good posture, as opposed to a bad posture?

I've never thought that 'memory' foam was a particularly good name...

What my back appreciates about it, is that, for instance, when I lie on
my side, my well-rounded hip sinks in to the mattress, but my waist is
still properly supported - it allows my spine to be straight, rather
than curving sideways to fit the flat, firm, surface of my previous
sprung mattress.

In very hot, humid weather, I add a fluffy cotton-covered mattress pad.
It slows down the shape-accommodation of the foam, but stops me feeling
hot and sticky.



Ah! That's very helpful. As you say, perhaps 'memory' foam is not the
best name. Thanks for clarifying.
