Sealy’s Casoli Latex features 1400 pocket springs for deep down support and long-lasting comfort. Each spring works independently, reacting to your individual shape and applying support where you need it the most. Unirail secures the springs in place and offers support right up to the very edge of the mattress. Latex responds to your body’s contours to provide excellent comfort and pressure relief, allowing you to find your most comfortable sleeping positon. Endorsed by Allergy UK, Sealy's Smart Fibres work to create a cool, fresh and dry sleep. Tencel has excellent moisture absorption properties, creating a positive environment that does not give bacteria a chance to grow. Purotex fibres work alongside Tencel by releasing microcapsules into the fabric of the mattress, keeping the sleep surface clean and extending its lifespan. Adaptive® technology regulates your temperature to prevent overheating during the night.
