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.
The third option is web suspension, in which bands of webbing across the seat and back. These are then attached to the frame to make a platform for the cushions. Webbing can be made of either natural or man-made fibers, and if it is used alone doesn’t make for very strong support. In better-quality sofas, it is used with a tensioner that fastens the webbing securely to the frame. The web suspension is the least preferable of the seating support options.
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.
