Featuring new and exclusive technology, the Excellence 1500 mattress is designed to offer comfort and support where your body needs it the most. Quantum Edge® is exclusive to Sealy and works to reduce the roll-off feeling, maximise comfort and offer the ultimate support right up to the edge of the sleep surface. A layer of Geltex complements the springs for added pressure relief and body support. Geltex also allows air to circulate through the mattress easily to prevent your body from overheating. Adaptive technology simultaneously absorbs moisture to regulate your temperature and keep you cool.
