Bonnell Spring Units

Bonnell spring units are a type of coil spring system commonly used in traditional mattresses. These springs are hourglass-shaped, wider at the top and bottom, and narrower in the middle. They are interconnected with a metal wire, forming a sturdy and supportive structure. Bonnell springs provide a firm, uniform feel and distribute body weight evenly across the mattress. While they offer good durability and affordability, they are less responsive to individual body contours compared to pocket spring systems. Bonnell spring units are often found in entry-level or budget mattresses and are known for their resilience and long-lasting performance.
