An innerspring mattress is a type of bed that uses a system of metal coils to provide support. These coils are designed to respond to your body weight, helping to distribute pressure evenly. This design can help you sleep more comfortably by reducing motion transfer, so if you share a bed, you’re less likely to feel your partner moving around. Innerspring mattresses come in various styles, including pocketed coils and continuous coils, each offering different levels of support and comfort. Many people prefer innerspring mattresses for their durability and breathability, making them a popular choice for a good night's sleep.
