Hi Ben,
 
Thank you for placing your question.
 
As you are sleeping on the Artisan href="https://johnryanbydesign.co.uk/understanding-beds/natural-plant-fibres-in-mattresses/" class="" >Naturals mattress which contains natural fillings, it would be advisable to add a topper that also has natural fillings in order to compliment the mattress and allow for breathability. 
 
A mattress topper is an additional comfort layer that is added to a core mattress to increase longevity and also increase the comfort of the mattress. We recommend that all mattresses should have a topper.  They are an excellent way of increasing the life of your bed and providing you with flexibility.

I would recommend our 5cm Latex topper which is made of 100% natural Latex and would give you an overall medium comfort which is the same comfort level as the Artisan Naturals.  This topper will allow you to sink in without being too soft and of course it will protect your mattress.  This topper does have the added benefit of being chemical free as it contains natural bio based raw materials.
 
I hope this assists but please feel free to give me a call on 0161 437 4419 should you require further information or advice.
 
Kind regards Julie
