Sealy Posturepedic Elevate Ultra Franklin FLEX Mattress (Firm)
The Sealy Posturepedic Elevate Ultra Franklin FLEX is the firmest option in the premium Elevate Ultra collection, specifically engineered for adjustable beds. Delivering a robust, comfortably firm feel exclusive to Sealy Posturepedic, it combines traditional innerspring support with advanced gel-infused comfort layers for deep orthopaedic alignment, pressure relief, and lasting durability—ideal for back and stomach sleepers seeking unwavering support.
Key Features
- FlexiCased® Edge Support – Reinforced perimeter edges ensure full stability while allowing the mattress to bend and flex seamlessly with adjustable bed frames, maximising the usable sleep surface and preventing edge sagging.
- AlignSupport® Coil System – Patented two-stage pocket springs (crafted from twice-tempered titanium) sense your body shape and weight, providing initial comfort followed by deep, consistent orthopaedic support for superior spinal alignment and resilience.
- MemorySense® ComfortCore® – Strategically placed in the high-pressure centre third with gel-infused foam for targeted lower back and hip support, enhanced pressure relief, temperature regulation, and extended mattress longevity.
- Gel-Infused Comfort Layers – Premium gel-infused foam combined with firm Sealy comfort fillings delivers a tailored, breathable feel that contours without excessive sinkage, promoting cooler sleep and long-lasting performance.
- UniCased® Edge Reinforcement – Interlocking keys secure the spring unit for corner-to-corner stability, a larger sleep surface, and reliable edge-to-edge support.
- Non-Turn Design – Rotate periodically for even wear – no need to flip.
- Allergy-Friendly – Hypoallergenic design with SmarTex® and ProShield® technologies to disperse heat, regulate temperature, and reduce allergens for a fresher sleep environment.
- Temperature Regulation – Breathable gel foam and air channels promote airflow for a cooler, more comfortable night’s sleep.
