Thank you for posting your question.
The coolest mattresses are those which are made of natural fillings and the more natural fillings the mattress contains, the better.
In our Ranges, our Artisan Mattresses from the Artisan Bespoke 004 to the Artisan Bespoke 002, all have 100% natural fillings. The difference between them is how the mattresses feel in the comfort layers. The comfort layers are all the fillings which are on top of the springs which you actually sleep on. The Artisan Bespoke 004 has medium comfort layers, the Artisan Luxury has soft comfort layers, the Artisan Bespoke has the firmest comfort layers and the Artisan Bespoke 002 again has a medium comfort layer but as it comes with a dual spring unit, this gives the mattress a slightly softer tension.
Each of the above mattresses can be made with different spring tensions which will then give you the correct support for your body weight. We would need to know the body weights of the people who will be sleeping on the mattress in order to give the correct advice. It may therefore be better to telephone our office on 0161 945 3757 where our advisers will be able to assist you further.
