The Ultimate Benchmark for Heavyweight Softness

450 GSM Knitted Mattress Fabric represents the pinnacle of "Hand-Feel" engineering. This ultra-heavyweight knit is designed to provide a Substantial Cushioning Layer even before quilting. By interlocking multiple layers of fine yarn, we achieve a fabric that has the weight of upholstery but the softness of a premium sweater. It is particularly effective at masking the feel of underlying tufts or spring profiles, providing a smooth, continuous sleep surface. The 450g weight allows for dramatic 3D sculpting, creating deep "valleys" and "peaks" that enhance both aesthetics and airflow.
