The BedzOnline 5FT King Ultra Cool Mattress blends cooling blue memory foam with a responsive open coil system for luxurious medium-firm comfort and expansive support. Measuring 155 cm in width and 200 cm in length, it cradles shoulders, spine, and hips while reducing motion transfer between partners for optimal shared sleep. The cooling stretch fabric cover promotes airflow, regulates moisture, and maintains a fresh and comfortable sleep surface throughout the night. Durable foam and coil layers provide edge-to-edge support, structural resilience, and long-lasting comfort, delivering deeply restorative, uninterrupted, and fully relaxing sleep every night for couples or larger bedrooms with premium performance.

To maintain the longevity and performance of your BedzOnline Ultra Cool Mattress, place it on a firm, supportive bed base or slatted frame that allows for adequate airflow. Avoid bending or folding the mattress, and do not stand it upright for extended periods. The cooling stretch fabric cover is breathable and moisture-wicking; however, it is not fully waterproof—clean spills promptly using a slightly damp cloth with mild detergent and allow the mattress to air dry completely. Regularly rotate the mattress head-to-foot every 2–3 months to ensure even wear and prevent sagging. While the mattress is designed with durable foam and high-quality open coils, avoid jumping or placing heavy, concentrated loads on it. Ensure that the mattress meets UK fire safety standards and is used in a smoke-free space to reduce fire risks. For optimal hygiene, use a breathable mattress protector. By following these guidelines, your BedzOnline Ultra Cool Mattress will provide consistent support, comfort, and restful sleep for years to come.
