The eight-way hand tied springs system is one of the best support systems. The craftsman connects each spring to the adjoining one with a strong twine. The twine passes front to back, side to side and then diagonally in both directions, thus tying each spring securely. Another method is sinuous spring construction. Sinuous springs are “S”-shaped and run from the front of the seat to the back. These springs are supported by additional wires that cross from side to side. This also makes for a strong seat, and it might be the preferred option in a sleeker style or smaller frame because it requires less space.
Engineered wood is just what the name implies. It has been engineered to achieve its present form. There are two types of engineered wood, plywood, and particle board. Particle board is not suitable for sofa frames, or any weight bearing frames for that matter because they are made from wood chips and fibers glued together. Plywood is engineered by gluing several thin layers of wood together and can be strong enough for sofa frames depending on the type of wood, and the thickness of the frame.
Just as your sofa shouldn’t be too big or too small for your space, it shouldn’t be too big or too small for you, either. If you are tall, make sure that the seat is deep enough to allow you to sit in comfort. If you are not very tall or have bad knees, look for a shallow seat that lets you rise out of it easily.
