Premium half-moon memory foam knee/bolster pillow designed to reduce pressure, relieve pain, and support natural alignment. Key benefits Targeted relief: The ergonomic half-moon shape fills the gap between neck and waist or between knees, reducing strain on the spine, hips, and pelvis. Lasting comfort: A slow-rebound memory foam core contours to your body and returns slowly to shape, minimizing pressure points and reducing fatigue. Versatile support: Use it for legs, knees, back, neck, or feet to promote muscle relaxation and improve posture during sleep, rest, or recovery. Easy care: The pillow has a zip closure so the cover can be removed and washed for a hygienic, fresh feel. What makes it stand out Ergonomic design precisely fits common body gaps to relieve targeted pain rather than providing generic cushioning. Slow-rebound memory foam offers balanced support and pressure relief, maintaining performance over repeated use. Removable cover with zip closure simplifies cleaning and upkeep. Practical use scenarios Side sleeping: Place the pillow between your knees to keep hips aligned, reduce lower back pain, and prevent knee rubbing. Reclining and reading: Use the half-moon shape at the waist or under the neck to fill gaps, reduce muscle tension, and support comfortable posture. Recovery and circulation: Put the pillow under the knees or ankles while lying down to relieve pressure, support rehabilitation, or improve comfort during extended rest. Materials and care Core: slow-rebound memory foam for contouring support and recovery. Cover: removable with zipper for easy washing and maintenance. Suitable for anyone seeking targeted support and improved comfort while sleeping, resting, or recovering.
