Cooling Gel Support: Features 7cm of solid, high-density 30D gel-infused memory foam. This advanced material provides superior body-contouring support to relieve pressure and promote spinal alignment, while the gel particles actively dissipate heat for a cooler sleep all night. Durable & Resilient: Engineered with high-resiliency, non-porous memory foam that resists sagging and maintains its shape over time. Unlike lower-density alternatives, our topper offers lasting durability and consistent, firm support for years of comfortable sleep. Deep Pocket Skirt: Designed with an extra-deep 45cm skirt to fit effortlessly over high-profile mattresses, pillow-tops, and mattress stacks. The flexible knitted fabric skirt ensures a seamless and secure fit without lifting or shifting. Breathable & Removable: The soft, breathable knitted skirt enhances airflow around your bed. The entire top cover is removable via a convenient zipper and is machine washable, making maintenance and hygiene effortless. (Note: Foam core is not washable). Easy Vacuum Packaging: Shipped in a compact, vacuum-sealed box for easy handling. Simply unbox, unroll, and allow up to 48 hours for the topper to fully expand to its 8cm height and for any harmless packaging odor to dissipate.
