The Sealy Mellbreak PostureTech mattress is a great option for those who struggle with aches and pains, thanks to the firmer level of support that it provides. Sealys bespoke PostureTech spring system is at the heart of the mattress, designed to provide long-lasting and deep-down support. The springs react to the weight and movement, applying support where your body needs it the most. Tucked inside the spring unit, Edge Guard works in unison to extend the sleeping area and provide added durability. Plus, a Powerpack is located in the center of the mattress offering additional support to the lumbar region, and works simultaneously with the spring unit to reduce any aches that are disturbing your sleep. The Sealy Mellbreak is double-sided with a tufted surface on each side, offering just as much support each time you turn and rotate the mattress. All Sealy mattresses are hand-crafted in Britain and come with a 5-year guarantee for extra peace of mind. Extra Firm mattress 28 cm depth is available in Single, Small Double, Double, King, and Super king sizes. 5-year guarantee handmade in the UK
