There are alternatives to kiln-dried hardwood frames. Metal sofa frames are available, too, but metal can be prone to oxidation along with seasonal changes. Changes in humidity can affect metal frames, so look for one that has been treated to protect against atmospheric changes. Plywood frames as long as they are thick enough can also work well. As a matter of fact, many leading manufacturers now use well-constructed plywood frames.
Just as your sofa shouldn’t be too big or too small for your space, it shouldn’t be too big or too small for you, either. If you are tall, make sure that the seat is deep enough to allow you to sit in comfort. If you are not very tall or have bad knees, look for a shallow seat that lets you rise out of it easily.
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.
