Froli Forti is a functionally sophisticated spring system made of flexible components that adapt to the body contour and weight of the user to provide pressure relief. These elastic springs are precisely tailored to the head, shoulder, back and foot areas and offer individually adjustable levels of firmness from soft to medium and firm. Thanks to their great number of springs and uniform flexing across the entire surface, pressure is evenly distributed. The pierced surface pattern also ensures active air circulation and ventilation of the mattress.
