We believe so strongly in our spring systems, that we guarantee their durability for a lifetime of use.DualFlex SpringDesigned to achieve the latest standard in superior seating comfort, the DualFlex Spring System uses thick, evenly spaced steel ribbons along the length of the frame from front to back.
