Issues relating to Artisan Naturals

1. Is the Artisan Naturals mattress cool to sleep on?
2. Are mattress toppers recommended for this range; if so do you supply them in natural fibres? Is a wool blanket an adequate substitute?
3. Does your firm spring tension equate roughly to the 'Extra Firm' option in the old Vi-Spring Regal Supreme?
4.Does the inclusion of drawers in an Artisan base affect its performance or perceived firmness?
I am very impressed with your website. We are considering replacing our (very) old Regal Supreme single mattresses; they have lasted remarkably well and are still comfortable, but nothing is forever. We would replace them with one Medium and one Firm Artisan Naturals. The sprung bases are still sound, so we will stick with them for the time being
