The Pocket Sprung Pillow is designed a little like a mattress, this is because miniature pocket springs lie at the heart of the pillow. These springs provide flexible support to ensure that your pillow never goes flat, keeping your head and neck fully supported and comfortable throughout the night. Similar to our mattresses, each of the springs is encased in it's own protective pocket and the entire spring unit is surrounded by soft and comfortable hollowfibre. The pillow is encased in a smooth 100% cotton cover that is naturally breathable and cooling.
