Upgrade your sleep with the Kingsdown Silent Partner X1 Firm Mattress, designed for optimal support, cooling, and pressure relief. Featuring the innovative XTech Support System, this mattress utilizes gradient wave coils in the center third, providing targeted lumbar support and relieving pressure on the shoulders and hips. Motion Separation Foam minimizes disturbances by absorbing movement between sleep partners, while dual reinforced-edge support coils create a firmer sitting edge and enhance overall durability. Stay cool and comfortable with XTech Cool Strips, embedded heat-releasing graphite strips that help regulate temperature and reduce heat transfer across the mattress. The XTech Carbon Thread Fabric, woven with trilobal carbon thread, helps release tension from the body and lower cortisol levels, promoting a deeper and more restorative sleep. To ensure a clean and hygienic sleep environment, Silver Anti-Microbial Protection actively minimizes allergens in the mattress. For added comfort, the quilting is infused with silk and hollo fibre, providing breathability, cooling, and a plush surface feel. The mattress also includes high-density firm foam and BluTek Gel Visco memory foam, which work together to deliver pressure relief and contouring support, making it ideal for those who need a firm yet comfortable sleep surface. Designed for lasting performance and superior sleep quality, the Kingsdown Silent Partner X1 Firm Mattress combines cutting-edge technology, firm support, and cooling innovation to create the ultimate sleep experience.
