Our Hybrid Mattresses can't be rolled, thanks to a stronger body contouring pocket spring core surrounded with high-density reflex foam which allows you to use the whole mattress for maximum sleep space. Fully upholstered with a deep layer of Flotex foam for a hypoallergenic surface that moulds to your shape, wrapped in a Tencel cool knit fabric to help you sleep softly. We designed the Essential Hybrid Mattress to be as easy to care for as possible. It's non-turn yet still rotatable and features side handles to assist turning and an airflow border. This makes for a lighter mattress than traditional pocket sprung models, and combines well with all base options so you're free to choose the design and style to complete your room.
