The steel wire used in Leggett & Platt’s high-quality innersprings makes each coil sturdy and resilient, even after years of use. Unlike units of lesser quality, our coils are tempered using heat or electricity so they bounce back to their original shape. After a coil is turned and shaped into its final form, tempering the spring realigns the molecular structure to ensure the coil won’t sag or settle over time. This greatly increases stability and durability.
