The Silentnight Anti-snore pillow is cleverly designed to help reduce snoring. Tested by the British Snoring & Sleep Apnoea Association, it was found to reduce snoring frequency and volume by approximately 50%. The pillow features an ergonomically shaped foam core that supports your head and neck, promoting better breathing which can help reduce snoring. This foam core is surrounded by soft yet supportive hollowfibre, making it suitable for back and side sleepers. The outer fabric is smooth, soft, and breathable polycotton. It comes with a two-year manufacturer's guarantee and is hypoallergenic, meaning it does not contain materials likely to cause allergies.
