      What the Sleep Expert thinks...

      "AlignSupport™ coils sense and react twice, first ensuring optimal comfort, then as they detect increased pressure, providing a deeper level of support. A plush ComfortCore™ layer targets your hips and lower back, which I think makes this mattress ideal for people looking for full-body, unmistakable comfort. Encased with UniCased® edge and SmarTex™ moisture‑wicking cover, the Arden Elevate Ultra Posturepedic delivers cool, pressure‑relieving lift in every sleeping position."

      Bursting with perfected sleep technology, the Sealy Arden Elevate Ultra Posturepedic Mattress is what innovation truly feels like. At Sealy, we have laboured over our love of making mattresses for generations. Everything we do today is rooted in the carefully crafted, and honed legacy of a spring system that is truly unique.The AlignSupport™ coil works in two stages, sensing and responding to your individual shape as you sleep. First of all, as your body relaxes into the mattress, the springs sense your shape, maintaining your natural posture and spinal alignment.

      The AlignSupport® coil then springs into action and applies the correct level of support, creating a feel that is completely personalised to you. On top of this, the springs are twice tempered making them even more resilient and durable. Working collaboratively with the spring system is our patented UniCased® XT, complete with BasePlank to bring structure to every point of the mattress. Creating a true halo effect around the mattress, UniCased® XT features keys that lock into the spring unit to prevent lateral movement each and every time you take a snooze. The coil-inspired air channels provide a more responsive feel and offer added breathability. It also creates a secure seating edge, perfect for putting your slippers on and our personal favourite, making it easier to hop into bed.

      When it comes to comfort, we know it’s personal. And that’s why we spend so much time and resource perfecting the comfort architecture within our mattresses. The Sealy Arden Elevate Ultra Posturepedic Mattress starts with the MemorySense™ ComfortCore™ placed in the centre third of the mattress to target your hips and lower back for the ultimate pressure relief. It’s followed by a generous helping of medium softness foam for a sumptuous feel. And finally, our very own InfiniLux™ - a luxe, premium foam that offers resilience and long-lasting comfort.

      Not only should your mattress feel good but it should look good too. The textiles have been expertly designed and selected to stand out, complete with SmarTex® and ProShield® for a clean and comfortable night’s rest. SmarTex™ is designed to wick away moisture to regulate your sleep climate, whilst ProShield® keeps allergens at bay. And you don’t just have to take our word for it, ProShield is endorsed by the Allergy UK.

      Last and by no means least, exclusive to the Elevate Ultra collection, the Arden incorporates a breathable air mesh border, allowing air to circulate through the mattress freely.

      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.

      Sealy’s Elevate Ultra range has been awarded the Good Housekeeping Award 2023. “It’s really comfortable, supportive and I have slept very well every night onthis bed. The quality is fantastic, and I feel this product will last me for years!" “It adjusts to my body perfectly and doesn’t make any noise!” - Good Housekeeping Expert Test Researcher

      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.
      MemorySense® ComfortCore™ icon
      MemorySense® ComfortCore™
      A heat-sensitive, body-moulding memory foam, the MemorySense® ComfortCore™ sits in the centre third of the mattress to provide added pressure relief to your hips and lower back.
