Designed with support and comfort in mind, the Serenity Ortho mattress features an extra firm pocket spring interior, topped off with a comfortable pillow top. The mattress is upholstered in a soft and luxurious knitted stretch fabric cover and boasts deep layers of soft fillings above its body-contouring pocket springs. Small in diameter and tightly nestled together, the pocket springs are house in their own cloth sleeve that allows them to move freely of any neighbouring spring. Being totally independent, the springs are free to follow the contour of your body, offering piston-like support where you need it most; the neck, hips and lower back. A high-density foam encapsulated border surrounds the perimeter of the spring unit, adding strength to the edge and allowing you the full use of the mattress width. As its one-sided, theres no need for the mattress to be flipped over, but we do recommend that you rotate it on a regular basis to enhance its support and comfort. Paired with a Lunar divan, you can create a bed that suits your needs and decor with a choice of base types, a range of storage options and a wide choice of colours and fabrics. Please note: Headboard is not included.. .
