Orthia Comfort Pillow Medium allows the anatomical correction of the cervical spine, leading to a relaxation of the neck muscles. In Orthia comfort pillow, latex type, are inserted three small clay discs (material with excellent anti-inflammatory properties and moisture absorption) into the foam. It is composed externally with cotton cover which is removable and washable up to 30C and inside with softfeel polyurethane foam or viscoelastic polyurethane foam. The pillow is designed to support the natural contours of head and neck area ensuring a blissful sleep day after day. Pillows provide support for your neck and upper back which is the most important role that the pillow needs to fill when you are asleep. People need this support when they are sleeping because the human spine is naturally curved. Having support for your head and neck helps to maintain the proper alignment of these areas of the spine.
