Question regarding weight and fitting of latex mattresses

I am looking to get a latex mattress for durability and because I sleep hot so memory foam is out of the question. I'm looking at getting the Dunlopillo Royal Sovereign as that seems to be a good fit for the majority of people without any particular sleep issues regarding firmness and I understand you have a similar product in the Fusion range.
I spoke to one of your helpful colleagues who mentioned however that I would not be able to use a slatted bedstead with your Fusion range. I have ordered a Warren Evans bedframe with slats, so what would you recommend in order to be able to fit a latex mattress, whether yours or Dunlopillo, on to my slatted base? I would have thought the slats would make the bed more mattress friendly, so would I have to cover the entire base with a sheet of wood? Would the weight of your mattress (70kg vs. 45kg for the Royal Sovereign) affect the durability of any bedstead?
Many thanks,
