The Heavy-Duty Luxury Benchmark

400 GSM Cotton Mattress Material represents the high-end density required for luxury "Pillow Top" and "Euro Top" mattresses. This weight provides a deep, opaque texture that perfectly masks the internal spring structures while adding a layer of physical cushioning. The high cotton content ensures that despite its density, the fabric remains breathable and soft to the touch. It is the gold standard for flagship models that require a substantial, durable, and premium-feeling surface.
