Prefer a firmer feel? The Blackwood mattress is designed to leave a spring in your step. At Sealy, we believe sleep is not just something we all do, or time spent in bed but more a question of when, where, why and how we can all sleep better. It all begins with a precisely engineered spring system, developed by our team of experts and totally unique to Sealy. The Align Support coil is our patented spring technology where neither comfort nor support are compromised. Its unique geometry senses your body as it meets the mattress, providing the initial response. Followed by deep down support that sits at the very heart of the coil to evenly distribute your body’s weight. It’s twice tempered too, providing dependable performance, year after year. Uncased encompasses the entire edge, meaning that you benefit from a larger usable sleep surface, and remove any rolling-off feeling. It also prevents lateral movement across your mattress throughout its entire lifetime. When you build something truly special, it’s important to have a solid foundation. That’s how we like to think of our Base Plank technology. Unifying and trustworthy, Bas Plank sits below the spring unit, providing structure from corner to corner, whilst offering breathability through multiple air channels. At Sealy, we go beyond comfortable... we’ve crafted true comfort. What’s that? It’s a refined comfort and I didn’t know until now, type of comfort, and a feeling that’s intrinsically... well Posturepedic. The comfort core is placed in the centre third of the mattress, positioned in the perfect spot for targeting your hips and lower back, providing that all-important pressure relief. Sitting alongside the comfort core are generous layers of Firm and Extra Firm foams, ideal for those who prefer a firmer feel. It’s not just our technology that makes us stand out from the rest, it’s our style that makes an impact too. Behind each fabric are years of true expertise and know-how, each design unashamedly bold to add that first-class feeling to your sleep space. Woven with SmarTex technology to disperse heat away from the skin and provide a cooler and cleaner night’s sleep. That’s not all, Pro Shield technology protects against allergens and aims to keep your mattress clean and fresh throughout its lifespan.
