Positioned at the top of the Ortho Plus collection, the Sealy Steeple PostureTech mattress offers the maximum combination of support and durability. 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 Steeple is a double-sided mattress with each side beautifully tufted for a firmer level of support. All Sealy mattresses are hand-crafted in Britain and come with a 5-year guarantee for extra peace of mind. Firm mattress 29 cm depth available in Single, Small Double, Double, King, and Super king sizes. 5-year guarantee handmade in the UK.
