92% natural latex: This sleepaid pillow uses 92% natural latex, delivering a light frankincense scent, a springy, resilient feel, and a nonslumping performance. It is miteresistant and antibacterial for a cleaner, more hygienic sleep surface. Functional Zone Design: Designed for cervical health, with dedicated zones for side and back sleeping, a deflection channel, a neck support area, and a neckback transition zone to support proper alignment. Suitable for various sleeping positions: When you sleep on your back, the design helps create a gentle height difference to stretch the cervical spine and reduce spinal pressure. When you sleep on your side, the height aligns with shoulder width to keep the shoulders and neck level and relieve pressure. SAP massage particles: Embedded SAP massage particles relax muscle tension, protect the cervical spine, and promote deeper, more restorative sleep.
