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.
Never buy a sofa without first trying it out. Sit on it, lie on it, try it out the way you would use it at home. If you like napping on your sofa, make sure that the arms are the right height. Make sure the cushions and the back are as soft or firm as you want them to be.
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.
