Wanted: Double Mattress must not be soft

All the details

Medium Firm Mattress for double slatted bed frame. I was given a really good quality one but the mattress is too soft and I am waking up with really bad back (I have arthritis of the spine) . One with memory foam or latex would be great but has to be over 15cm deep because of bed frame. THANK YOU
