Core Structure of Roll-Packed Mattresses

The core structure of a roll-packed mattress typically consists of a comfort layer, a support layer, and a protective layer. The comfort layer often utilizes memory foam, latex, or high-density foam, while the support layer generally employs pocketed springs or high-resilience polyurethane. When selecting materials, manufacturers must balance compressibility with resilience; if the materials lack sufficient fatigue resistance, the mattress may fail to fully recover its shape or suffer from sagging after prolonged periods of being rolled and compressed.
