It's a pocket sprung mattress so it has hundreds of individual springs each contained within its own little pocket. This means the springs move independently to support the contours of your body. It has vents for enhanced air flow keeping the high loft polyester filling fresh expelling any stale odours before they build up. The mattress is double sided so you can give it a regular flip and rotate to help it wear evenly effectively prolonging its lifespan.
