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.
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.
In a good-quality frame, the joints get special attention. They are glued, dowelled, and screwed. The corners are further strengthened by the addition of reinforcing blocks for extra support and strength. Generally speaking, plywood and particleboard frames are inferior, especially if they are held together with staples. Additional layers of plywood can help reinforce the frame, so as you can see, construction matters as much as material. If you must choose a sofa with a plywood frame, make sure it has at least 11 to 13 layers of plywood.
