A spring mattress uses a system of coils to provide support and a bouncy feel, but it may lack the targeted pressure relief needed for certain pain conditions. An orthopedic mattress, on the other hand, is specifically designed to support spinal alignment and relieve pressure points. While its construction usually contains a spring coil system, it often features advanced materials like memory foam, latex, and zoned support systems to offer enhanced comfort and support for those with orthopedic issues.
