Spring mattresses use high-carbon steel or alloy steel springs, employing precise heat treatment and rolling processes to ensure both excellent elasticity and durability, preventing deformation. Individually pocketed spring technology allows each spring to bear pressure independently, improving conformity and support for different parts of the body. Connected springs, on the other hand, ensure a flat surface and balanced weight distribution through overall integration. Beyond springs, comfort layer materials are also constantly evolving. Latex, memory foam, and gel materials, through scientific formulation and layered design, achieve even pressure distribution, temperature regulation, and optimized breathability. Some high-end mattresses also utilize zoned support technology, dividing the mattress into different zones for the shoulders, waist, and hips, each using materials with varying firmness to more precisely conform to the body's curves.
Spring mattresses also incorporate advanced technology and intelligent design. For example, quilting secures multiple layers of filling material, preventing shifting; breathable mesh and antibacterial fabrics enhance mattress cleanliness and health. Some smart mattresses feature temperature regulation, body pressure monitoring, and even automatic firmness adjustment, making the sleep experience more personalized and scientific.
