Handmade in Britain and part of the Campaign for Wool Collection, whose patron is HRH The Prince of Wales, the Sleepeezee Wool Superb 2800 mattress uses Platinum British Wool which is natural, breathable and will help regulate your body temperature, keeping you rested and peaceful all night long. The triple layer of pocket springs will offer you comfort and support for all body shapes. The pocket spring system is the best at providing individual support to the sleeper. The upper part of the spring shapes to the body contours while the lower part absorbs changes in weight distribution for the ultimate in comfort and support. As a rule of thumb the higher the number of individual springs, the more support will be provided to the sleeper. The springs work independently to avoid roll together. The Wool used in this mattress has been awarded the Platinum Certificate and is guaranteed by the British Wool Marketing Board for its high quality and exacting standards. It is sustainable and renewable and has been cleaned without the use of bleach or chemicals and is lovingly made in England. Wool is used in this mattress as a soft and insulating upholstery layer for added comfort. Wool is a natural insulator providing coolness in the summer and warmth in the winter. Offering superb comfort, it also has hydroscopic properties encouraging the evaporation of body moisture. A cotton layer with responsive properties that complement the spring unit is added to the mattress to help provide a comfortable feel and enhances breathability. This mattress comes with a 10 Year Guarantee.
