It uses twin layer pocket spring technology to promote outstanding back care and comfort. A zip and link mattress is a set of two 2ft6in Small Single sized mattresses or two 3ft Singles which can be firmly attached together to form a 5ft Kingsize or a 6ft Super King mattress.The pocket spring system consists of 2400 individually moving springs each nested in their own fabric pocket. This provides a great balance of support and comfort in key areas by moving to the contours of your body. What makes this mattress really special is the twin spring unit, consisting of two layers of springs. Both layers house the same sized springs, which work together to form a supportive foundation and a comfortable top layer while the mattress remains double-sided.Generously stuffed with cotton, lambswool, hand teased mohair, hand teased horse hair, cashmere and silk, this mattress has an impressive filling content. The Grandee is hand tufted to help these fillings sustain plumpness long into its lifespan. Silver+ Protection is a coating based on the microparticles of silver ions, designed to dramatically reduce microbial grow for a fresh and hygenic fabric. The sleeping area is extended right up to the edges because of four rows of hand stitching supporting the mattress walls.In the king size model of the divan base, there are 1000 pocket springs top of a solid timber frame. This rigid yet comfortable system provides outstanding results.Please note: although the picture shows a skirted divan, the product we are selling has a pocketed bumper bar instead. Please call customer services for more information on this.
