Cotton Felt

“Felt” in a mattress refers to a thin, fabric-like material, usually made from recycled fibers, that is used as a layer within the mattress construction, acting as a protective barrier between the spring system and the comfort layers, providing cushioning and helping to distribute weight evenly across the mattress for better support and comfort ; essentially, it’s a soft, dense pad that helps prevent noise from the springs and enhances the overall sleeping experience.
