Hi Jay,
 
Apologies for the delay in responding we've had an incredibly busy new year.

The issue with the orthos latex that you have probably uncovered is they give you no detail on the type of blend of Latex in the mattress. Without this, you are buying blind. You really need to know the blend, manufacture method and density of the latex, we explain more here.

We make two firm latex and pocket spring mattresses the Fusion zero, with 10cm of natural latex in total or the Origins Pocket Latex (firmer still) with 6cm of Talalay latex. If you want a real extra-firm feel with latex have a look at our Resilience range here.

I'd be happy to explain the two if you want to drop us a line and see whats best for you.

Many thanks Lee
