What’s the difference between innerspring and foam mattresses?
• Innerspring mattresses—The most widely purchased type of mattress. These mattresses feature tempered steel coils in a variety of configurations. Layers of upholstery provide insulation and cushioning between your body and the spring unit. Serta offers a variety of advanced and durable innerspring systems. • Foam core mattresses—Instead of coils, these mattresses use either latex or visco-elastic memory foam cores as the support system.
