Engineered for firm support with enhanced comfort, the Cool Rock Mattress by Arthur Sleep combines pocket springs with advanced foam layers to create a responsive hybrid design. Offering an extra firm feel, it features body-contouring memory foam alongside supportive soft foam to help distribute weight evenly and reduce pressure points. The pocket spring system works independently to provide targeted support and minimise motion transfer, making it a reliable choice for a stable and supportive sleep surface. Part of the Arthur Sleep Cool Arthur range, this mattress is designed with temperature-regulating properties to help maintain a cooler feel throughout the night. Finished with a hypoallergenic quilted fabric cover, it promotes a fresher sleeping experience while remaining gentle on the skin. Conveniently rolled and vacuum-packed for easy delivery, it also includes handles for easier positioning and is backed by a 10-year warranty for long-lasting peace of mind. - Arthur Sleep Cool Rock Extra Firm Hybrid Mattress in White - Size: Single
