The BedzOnline 4FT6 Double Ultra Cool Mattress combines high-density memory foam with an open coil system to deliver medium-firm comfort and ergonomic support for couples. Measuring 135 cm in width and 190 cm in length, it offers ample room for two people while cushioning shoulders, back, and hips and promoting proper spinal alignment for healthier sleep. The cooling stretch fabric enhances breathability, moisture control, and overall surface freshness, keeping your bed inviting night after night. Durable foam and coil layers provide resilience and structural stability, ensuring deeply restorative, uninterrupted, and fully refreshing sleep every night in any bedroom setting.

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.
