Spring mattresses, are a popular type of mattress that utilizes a system of metal coils or springs to provide support and comfort. These coils are typically made from steel and are arranged in various patterns to distribute weight evenly across the mattress surface. The coils are then covered with layers of padding, foam, and fabric to enhance comfort and cushioning.

Spring mattresses come in different firmness levels, from soft to firm, to provide different sleep preferences.

Ultimately, the choice between spring mattresses and other types (such as memory foam or latex) depends on personal preferences for comfort, support, and sleep conditions.
