"Designed to balance responsive support with a softer feel, the eXtreme Comfort Diamond memory foam and spring hybrid mattress combines adaptive springs with plush foam layers for a soft-to-medium comfort level that helps support natural body alignment. With an 18cm profile, it’s a considered choice for smaller beds and space-conscious sleeping set-ups, including bunk beds, guest rooms and apartments. An advanced sleep fabric enhances airflow for a more breathable, cooling surface, helping to maintain a comfortable temperature through the night. Handmade in the UK and crafted in Yorkshire to meet UK fire safety standards, it’s finished with practical delivery in mind: the mattress arrives vacuum-sealed, rolled and boxed for easier transport, then expands to full size within hours of unpacking.
