      What the Sleep Expert thinks...

      "Precision‑engineered AlignSupport™ coils team with firm comfort foams for an unmistakably solid feel, yet every move still feels buoyant thanks to BasePlank stability. This mattress is perfect for those who love a firmer sleeping surface, which in my opinion, helps you feel secure and properly supported all night long. A UniCased® edge lets you sit or sprawl without sag, and ProShield® allergy protection keeps the Blackwood fresh night after night."

      Prefer a firmer feel? The Sealy Blackwood Elevate Posturepedic 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 AlignSupport® 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.

      UniCased® encompasses the entire edge, meaning that you benefit from a larger usable sleep surface, and removing 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 BasePlank technology. Unifying and trustworthy, BasePlank 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, an “I didn’t know until now”, type comfort, and a feeling that’s intrinsically... well Posturepedic. The ComfortCore™ 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 ComfortCore 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.

      And that’s not all, ProShield® technology protects against allergens and aims to keep your mattress clean and fresh throughout its lifespan. Endorsed by Allergy UK.

      At Sealy, it’s our mission to create mattresses that last and that’s why all Sealy Posturepedic mattresses come with a 7 year guarantee. Handmade right here in Britain.

      AlignSupport® Coil Springs icon
      AlignSupport® Coil Springs
      The AlignSupport® has been carefully constructed and evolved over time to be a two stage coil. First, it senses your individual shape as you rest into the mattress, followed by an instant response that applies deep down, consistent support. Also, you can sleep soundly knowing that the spring unit is twice tempered which means it’s twice as strong and durable - impressive, we know.

      Fabulous, since I got it a few days ago ive slept right through the night. I have a bad back which usually wakes me when I turn but not on this mattress, bliss. I think it's good value for money as well. Very happy customer. I've had a sealy before but the last mattress I went for a different brand but i'll be sticking to sealy from now on
