Hi James, 
 
Thanks for your question. 
 
You're absolutely correct that the general rule is to pair the topper with something close to the mattress fillings. 
 
As such our toppers aren't really suitable for use with the Artisan range of mattresses as you pair foam with foam, latex with latex etc. 
 
Our advice is to look at a company online called Soak and Sleep. They will have a much wider range of toppers than we do and you ideally want to be looking at something along the lines of Wool or Microfibres. 
 

 
What I would advise is to use the mattress by itself for 4-6 weeks first to get a true feel for it. Under this period just use a standard mattress protector instead. Save yourself the expense at the beginning because the mattress might be fine without one. 
 
The Artisan Bespoke 004 is a true medium feeling in the top layers providing that slight sink in sensation but not too much. The 100% natural fillings also give you a very cool sleep surface; Ideal for anyone who identifies a hot sleeper. 
 

 
We'd need to know body weights to discuss correct spring tension but below are our general guidelines on spring tension vs body weight;
