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.
Down used in combination with other materials is also a good option but also another expensive option. Pads made out of a Dacron polyester fiber and down, known as Blendown pads, are wrapped around high-density foam. These pads can also be used with springs that have been wrapped up in foam. High-density foam surrounds the springs, which are then wrapped in down pads. The result is a soft surface with a strong, resilient support inside. This is a good option because the cushions do not lose their shape easily.
The seating support is also an important component in determining the quality of a sofa. It works in tandem with the frame and the filling. A sturdy frame provides an anchor for good seating support and filling augments it. You should always test the quality of seating support by sitting on a sofa before you buy it. It shouldn‘t sag, and it should provide good support in the seat and in the back.
