The Relyon Bliss employs a combination of natural fibres and pocket mounted springs to provide you with all-night support and premium comfort. Bamboo, alpaca, and wool are used to create a mattress that adapts to the changing seasons, helping you to stay cool in the summer and warm in the winter. Rated as a medium mattress, it�s an excellent choice if you find softer designs don�t provide the required support.The Relyon Bliss is a double-sided mattress that can be flipped and rotated regularly if you wish to extend its expected lifespan. To make this easier, handles have been integrated into the design. The mattress also comes with an 8-year guarantee, so you can make your purchase safe in the knowledge that your mattress is protected.?The Relyon Bliss contains 1000 springs, each of which is packed into its own fabric pocket. This allows the springs to flex independently of one another, resulting in a more versatile and responsive spring system that�s capable of adapting to subtle movements and provides targeted support.Natural wool, alpaca and bamboo fibres are worked into two comfort-enhancing layers - one either side of the Posturepocket� spring system. These layers act as a natural insulator, keeping things fresh and cool in warmer weather and ensuring you stay toasty when winter arrives.Firmer springs line both edges of the design, preventing the sides from sagging as the mattress ages and expanding the amount of comfortable space you have at your disposal. While many mattresses lose their structural integrity over the years, the Relyon Bliss stays strong, thanks to its reinforced sides.
