Product Description & Application

Double Cone Springs,also known as Bonnell springs,are typically used for spring support in traditional upholstery and divans. Many different sizes are available to suit individual applications. Our springs are manufactured in plain finish and to the highest of standards for maximum comfort and reliability.

Mainly used in the upholstery trade, these springs are often used in seating applications and mattresses of better quality.Springs are open coiled, with a larger diameter at each end. The idea being that they can be compressed, so that they ‘almost’ collapse under compression to a single wire diameter, while maintaining their strength to return to the uncompressed state when released.They are made from standard spring wire, or given special criteria in other grades. But this is not usually necessary as they are rarely used in harsh environments or corrosive atmospheres.
