A quality chair or sofa will employ some type of inner spring system, usually in the back as well as the seat area. These systems add comfort, as you might expect, but they also work to take some of the stress off the joints of the frame. Here are some of the spring systems being used:

First up, we have the coil or cone spring system. This quality system uses eight-way, hand-tied double cone springs to provide extraordinary comfort and support. This technique involves fastening the cone springs tightly to the base and expertly tying their tops together with a strong cord. This is the only system that allows for side-to-side movement in addition to up and down movement. Hand-crafted quality comes at a price, though, and while this is widely considered the best spring system, it is also the most expensive.

Next, we have the sinuous wire spring, which is made in a continuous zigzag or "S" shape. These wires run parallel to each other and are fastened directly to the frame and to each other. Similar to this system is the formed wire spring, whereby the continuous wire is formed into rectangular bends and angles instead of the zigzag pattern.

Finally, the grid suspension system is composed of a wire grid, sometimes covered with paper or plastic-coated wire, which has one side fastened directly to the frame. The other side is connected to the frame by helical springs. This is also a very common system that is used widely.

If a chair or sofa doesn't use one of the aforementioned inner spring systems, it's probably a good idea to steer clear of it. Some manufacturers use elasti
