The spring and web of your sofa can define its quality, price, stability, and lifespan providing your sofa the needed support. That’s why you should ask the salesman about the type of the spring or web of the seat and back cushions to define the perfect sofa for your needs. Instead, you can test the sofa yourself removing the seat cushions and testing the inner springs with your hands.
For a high quality sofa that will tolerate your heavy use, you should get a sofa with coil or cone spring system or 8-way hand-tied springs , as each spring coil has a twine connecting it to the other springs and the frame in eight diagonal and side by side patterns. You will recognize such a spring type whenever you sit on the sofa and go up and down easily and when you break your budget to purchase such a sofa.
You will easily recognize the sinuous or serpentine springs by their zigzag S shape. Such springs are made of steel wires or copper-coated springs to match most of the modern sofas, especially the sofas with low and sleek designs.
The web suspensions are usually used with other types of springs, as they add weak support to the sofa. You will recognize such a type of webbing through its two to three inches of web bands at the seat and back creating a hammock-like base below the cushions. If you need a flexible base for your sofa’s upholstery, the fabric or rubber elastic web is your perfect choice, as it surrounds your sofa’s upholstery from the front and back for more support.
Such types of springs and webbing are covered with a layer of canvas and several layers of stuffing, filling, and padding covered with another layer of canvas and fabric or leather. This way, you and your guests will never feel the presence of such springs whenever you sit on the sofa. The density of seat and back cushions will define the sofa’s degree of comfort and its shape.
