Hi, Re your comments about foam mattresses.

My daughter and her partner have a foam mattress (bought in Germany}.

It is 10 years old now and is as good as new.

When my wife and I visit, they give up their bed for us.

This is because I have arthritic problems.

When I wake up during the night to pay a visit, I feel truly, truly weightless lying there, no other mattress has had this effect upon me.

For me, foam mattresses are unbeatable.

Thanks for the chance to comment.
