Bed slats are long, narrow pieces of wood or metal that support a mattress in a bed frame. They are typically arranged in parallel lines, spaced evenly apart, to provide a stable foundation. This design helps distribute weight evenly, ensuring that the mattress remains supported and comfortable. In addition to providing support, bed slats also promote airflow beneath the mattress, which can help prevent moisture buildup and extend the life of the mattress. They come in various sizes and materials, allowing for customization based on the type of bed frame and mattress used.
