The Sealy Elevate Ultra Franklin Firm Mattress has been expertly crafted for those who enjoy a firmer sleeping surface combined with advanced pressure relief and long-lasting support. Designed as part of Sealy's premium Elevate Ultra collection, this British-made mattress brings together innovative sleep technology, breathable comfort layers and dependable durability to help you wake feeling refreshed every morning.
At the heart of the mattress is Sealy's exclusive AlignSupport® Coil spring system. This advanced two-stage spring technology is designed to sense your body's unique shape before responding with targeted, deep-down support exactly where it is needed. The twice-tempered springs are engineered for exceptional durability, helping the mattress maintain its supportive feel for years to come whilst promoting healthy spinal alignment throughout the night.
The Franklin Firm also benefits from UniCased® XT edge support, creating a stable edge-to-edge sleeping surface that maximises the usable sleep area. This innovative edge support system prevents lateral movement around the perimeter of the mattress, allowing you to sleep comfortably right to the edge whilst also providing a secure seating edge when getting in and out of bed. Integrated air channels within the edge support also encourage increased airflow for a fresher sleeping environment.
For enhanced comfort, the mattress features Sealy's MemorySense® ComfortCore™, strategically positioned through the centre third of the mattress to deliver targeted pressure relief to the hips and lower back. Working alongside a breathable gel-infused comfort foam, this layer helps cushion the body's key pressure points while maintaining a supportive feel. Additional layers of Sealy Firm Foam complete the comfort system, creating a robust and supportive sleeping surface for those who prefer a firmer level of comfort.
Temperature regulation is equally impressive thanks to the premium fabric, which incorporates SmarTex® technology to help disperse excess heat away from the body as you sleep. The cover also features ProShield® technology, endorsed by Allergy UK, helping to reduce allergens and maintain a cleaner, fresher sleeping environment. Combined with the breathable BasePlank foundation, which encourages airflow throughout the mattress, these features help create a cool and hygienic place to sleep all year round.
As a single-sided mattress, the Sealy Elevate Ultra Franklin Firm requires no turning, simply rotate it from head to toe periodically to maintain its performance. Handmade in Britain using premium materials and backed by a 7-year guarantee, this mattress offers the perfect combination of firm support, advanced comfort technology and exceptional durability. Whether you are looking for enhanced spinal support or simply enjoy a firmer sleeping surface, the Sealy Elevate Ultra Franklin Firm Mattress is an excellent choice for years of comfortable, restorative sleep.
