The Relyon 'Allegro' is a luxurious no turn pillow top pocket sprung mattress. The combination of the pocket spring and the pillow top layer which features additional mini pocket springs distribute body weight evenly to minimise pressure on the body to provide postural support. The mattress has a layer of cashmere hair and silk fibres for durable insulation. Its firm edge support provides strength to the mattress sleeping area and its wool hand tufting ensures that all loose fillings are secured to guarantee a perfect finish.
