  • Bonnell springs, the classic spring system, provide standard solutions for those who do not compromise on flexibility and durability.
  • Larger head diameters provide greater surface area with the hourglass form, while narrower core diameters support body weight and provide user confidence.
  • The number of springs in the metric range ranges from 90 to 200 and offers different comfort solutions for different needs.
  • Zoned series with different wire thicknesses and head diameters make special productions that go beyond the standard.
  • With the Roll-pack and Flat-pack packaging methods, the springs pass through the tearing process, and the spring height does not change even after many years.
