How can I make memory foam healthy?

I bought an ergoflex memory foam mattress - I found it very comfortable but got really stressed about the amount of potential negative health issues being bandied around in connection with these mattresses.

I then researched and have bought an Essentia Beausomment mattress from Canada at around £2800.

This is sold as a healthier alternative to memory foam - a latex core with a 'natural' memory foam top.

This is sitting on a brass bed with some chip board as a base.

This new mattress feels quite soft and I am getting a degree of back discomfort.

I really like the idea of a healthy mattress, but wonder if I can do anything to make it more comfortable Do you know anything about these mattresses and would it be better on a different type of base.

I am hoping you don't mind me asking this question, but you seem to be full of excellent knowledge and advice.

Many thanks Sarah.
