The Sunglow from Silentnight is a wonderful mattress that features 1400 individual pocket springs with layers of natural wool fillings that will provide you with a supportive yet luxurious level of comfort. 1400 Pocket Springs - 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. Wool Layer - 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. Cotton Layer - 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. Hypo-Allergenic - Dust mites cannot survive on the product, allowing a healthy environment and peaceful sleep, which is ideal for Asthma and allergy sufferers.
