Relyon Finesse Mattress utilises the innovative Posturepocket� spring system to deliver outstanding support. The perfect choice if you�re looking for a medium-soft mattress, the Finesse Mattress also features a range of natural fibres, including bamboo, wool, alpaca, cashmere, and silk. These materials help regulate your temperature whether it�s hot or cold and ensure you benefit from premium comfort. A probiotic fabric treatment also keeps allergens, bacteria, and odours at bay.The Relyon Finesse is a double-sided mattress and can be flipped and rotated to extend its lifespan. To help with this process, handles have been built into both sides of the design. The mattress is also sold with an 8-year guarantee, allowing you to make a purchase safe in the knowledge that you�re receiving a product of the highest quality.Each spring used in the Relyon Finesse king-size mattress is mounted in its own fabric pocket and moves independently of the other springs in the Posturepocket� system. This allows the mattress to respond to pressure and movement in a more subtle way, providing excellent support in those places you need it most.The mattress features two layers of natural fibres, both of which work to ensure you enjoy outstanding comfort all year round. The first includes a combination of bamboo, wool and alpaca fibres and functions as natural insulation, keeping you warm in the winter and cool in the summer. The second includes wool, cashmere, and silk. This luxury layer helps you stay cool and dry at all times.Both edges of the mattress have been strengthened with firmer springs to prevent sagging and loss of structural integrity. While many mattress designs begin to collapse at the edges after a relatively short period of time, the Finesse Mattress retains its shape, ensuring you benefit from more usable space � especially useful if you like to spread out or �starfish� when you sleep!.
