Bed liners, also known as underpads or bed protectors, are absorbent sheets designed to protect mattresses, bedsheets, chairs, and other surfaces from moisture due to incontinence, spills, or medical procedures. These liners typically consist of multiple layers: a soft, quilted top layer that provides comfort against the skin, a highly absorbent core that locks in liquid, and a waterproof backing that prevents leaks from reaching the bedding or furniture underneath. They are available in both disposable and reusable options. Disposable bed liners are made for single use and easy cleanup, while reusable versions are washable and often made with more durable fabric. The liners are designed to lie flat and stay in place, offering a quiet, non-crinkly surface that promotes restful sleep without disruption.
