What is firm pillow?

A firm pillow is a type of pillow designed to provide strong support for the head and neck, maintaining proper alignment during sleep. It typically has a denser fill material, such as memory foam, latex, or tightly packed synthetic fibers, which helps prevent the head from sinking too deeply. This makes firm pillows ideal for back and stomach sleepers who require more elevation to avoid strain. Overall, they cater to individuals seeking a stable sleeping surface for enhanced comfort and spinal alignment.
