A pillow is a fundamental support system for the head and neck during sleep, designed to maintain spinal alignment in a neutral position. Its effectiveness is determined by its fill material, loft (height), and firmness, which must be matched to an individual's preferred sleep position. Side sleepers generally require a higher loft and firmer pillow (e.g., memory foam) to fill the space between the ear and shoulder. Back sleepers need a medium loft pillow (e.g., down or latex) to support the natural curve of the neck without pushing the head too forward. Stomach sleepers often benefit from a very soft, low-loft pillow (e.g., down alternative) to minimize neck strain. Beyond support, pillows contribute significantly to sleep hygiene and comfort through their outer materials, which can offer cooling, moisture-wicking, or hypoallergenic properties. The right pillow can drastically improve sleep quality, reduce pain, and alleviate snoring. In interior design, pillows are also key decorative elements on beds and sofas. From a maintenance perspective, using a protective pillowcase and periodically fluffing the pillow are essential for longevity.
