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.
Make sure that you are getting high-density foam because lesser-quality foam can start breaking down pretty quickly, causing sags, and the fabric does not stay taut when that happens. If you want a really soft seat, consider down cushions. These are considered to be the premium choice, and as you might imagine they are also among the most expensive. High-quality cushions have down-proof ticking under the upholstery fabric to prevent feathers from poking through. Cushions filled just with down are high-maintenance and can need daily attention.
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.
