Experience superior comfort and support with the DuraTribe Goldensleep Smart Memory Foam Mattress. This 15 cm deep mattress provides excellent orthopaedic support by moulding to your body, relieving pressure and distributing weight evenly. Designed with a top layer of 4th generation visco-elastic memory foam and a high-density, high-resilience foam core, it minimizes motion transfer for undisturbed sleep. The micro-quilted, removable PolyBlend cover, combined with open-cell memory foam, enhances air circulation for optimal temperature regulation. This mattress is hypoallergenic, antibacterial, and anti-dust mite. It arrives vacuum-packed for easy handling and expands within 24-48 hours. Suitable for all bed bases and frames, including bunk beds. Please unpack within 7 days of delivery and allow to fully expand in a well-ventilated room. Colder temperatures may extend expansion time.
