Thank you for your post

Unfortunately she was off again today with bad back pain and thankfully the doctors are now giving her physio but our mattress is indeed soft and a look at the logo on there confirms that it's 'regular' as opposed to firm or extra firm.

It's not that old but it even bows down slightly in the centre and so I'v been looking on the internet to research mattress and came across something called memory foam.

Are these any good? It sounds like it wouldn't last too long but are they really too good to be true?
