Product Description & Application
Double Cone Springs are supplied to upholsterers looking to produce furniture in the “8 way hand tied” method. Double cone springs are used mainly on traditional sofas and chairs etc.
The “double coil” spring has a larger open coil at each end. They are sold by Tons, but you also can buy the number as you require. They are available in different heights and firmness.
They must be fastened to a webbed, wood or metal strap seat foundation. Next, they are anchored to the frame.
This is done by tying them to the desired height and firmness using spring twine. Sometimes this is referred to as “8-way hand tied”. This is the best way, but not all tying follows this method.
8-way Hand-tied Springs
An 8-way hand-tied spring system is a tried and true technique that requires skilled craftsmanship. To make 8-way hand-tied coils, laborers tie springs eight ways, from side to side, front to back and diagonally. This helps craftsman build upholstered furniture that is soft, supportive, flexible, and comfortable.It takes more time and labor to build 8-way hand-tied spring systems and furniture pieces featuring this type of construction are typically more expensive. While you’ll spend more money upfront on living room seats, their long-lasting quality prevents you from having to spend money on future replacements.
