Zigzag springs are among the most popular choices in upholstered furniture manufacturing. They are mounted at equal spacing along the furniture frame. Thanks to their curved, serpentine shape, these springs are both flexible and durable. As a result, upholstered furniture retains consistent seating comfort throughout its use.

These are cone-shaped metal springs combined with a polyurethane foam and felt base. This type of spring ensures excellent air circulation, helping to prevent moisture build-up inside the mattress. Mattresses with Bonnell springs respond quickly to changes in body position. As the springs are firmly connected to one another, they tend to move as a single unit, offering firm and uniform support.
