The Copper Arthur 2000 Mattress by Arthur Sleep is a premium medium-firm hybrid designed to deliver advanced support with enhanced cooling and hygiene benefits. Combining a high spring count with layered foams and a copper-infused cover, it offers a balanced and breathable sleep experience. At its core, 1000 pocket springs provide structured support, while an additional 1000 mini springs increase responsiveness and evenly distribute weight. A 40mm memory foam layer works alongside additional comfort foams to contour to the body and relieve pressure, supported by convoluted foam for improved airflow and cushioning. The luxury knitted cover is infused with copper, helping to create a cooler and fresher sleep surface with added antibacterial properties. Foam encapsulated edges provide enhanced edge-to-edge support and maximise the usable sleep area. With an extra-deep 35cm profile, this mattress delivers a substantial, supportive feel suited to everyday use. Hypoallergenic materials make it suitable for allergy-conscious households. Delivered rolled and vacuum-packed for convenient setup. Backed by a 10-year warranty.
