The Chelsea mattress is designed to deliver reliable comfort and practical support, offering a well-balanced medium feel that suits a wide range of sleeping styles. Carefully engineered to promote correct spinal alignment, it provides consistent cushioning while helping to relieve pressure across key areas of the body for a comfortable and restorative nights sleep. The mattress is constructed using a durable open coil spring system, formed from a continuous wire to create a supportive and resilient core that offers excellent stability while remaining lightweight and easy to handle. Finished with a traditional tufted surface, the internal layers are securely held in place to maintain long-term comfort and shape retention. The sleeping surface is covered in a high-quality knitted fabric, selected for its softness, breathability, and gentle stretch, creating a comfortable and inviting sleep. Designed as a single-sided mattress, it features a dedicated sleeping surface with supportive comfort layers, while the base is finished with a non-slip fabric to help keep the mattress securely positioned on the bed frame. With an approximate depth of 25cm, the Chelsea mattress offers a supportive and practical sleep solution, making it particularly well suited for guest rooms, spare bedrooms, and everyday use where comfort, durability, and ease of use are essential. - Chester & Oakley Chelsea Comfort Open Coil Mattress in White - Size: Single
