Royal Sovereign by Dunlopillo at Mattressman

Customer Price

Royal Sovereign  Main Image


Dunlopillo, the natural sleep specialist, makes mattresses from the highest quality latex, an eco-friendly material that has all of the body-moulding qualities of memory foam but none of the drawbacks.
Inside the latex core is a network of tiny airways that ventilate the mattress as you move, delivering a cool, dry sleeping environment that will leave you feeling fresh and revitalised each morning. The latex is also divided into 7 areas of varied tension. These are called comfort zones, and they tailor support beneath lighter and heavier parts of the body, allowing key joints such as the shoulders and hips to sink deeper into the mattress, providing excellent postural support and keeping the spine neutrally aligned.
It may surprise you to learn that it takes one tree 500 days to produce enough latex to make a single mattress, which begs the question: why does Dunlopillo use it? Well, latex is incredibly durable. It's so hardy, in fact, that every Dunlopillo mattress comes with an incredible 8-year guarantee. What’s more, because latex is so hard wearing, you can expect your Dunlopillo mattress to perform and feel exactly the same after several years of use. Latex is also antibacterial, antifungal and dust mite resistant.
To top it off, the soft knitted cover is treated with Actipro, which protects against allergens and the development of odours.
If you’re still not convinced that the Royal Sovereign is the right mattress for you then get down to one of our stores and try it out for yourself. We’re confident that you’ll be a fan!
N.B. This mattress must be used in conjunction with an air-permeable base. You can find our specially designed air-permeable bases in the drop-down menu above. Alternatively, you can browse our selection of slatted bed frames to complete your order.
