Wood can hold a lot of moisture when it is first harvested. What makes a kiln-dried frame better is that the process gets rid of most of the moisture inside the wood. Kilns are huge ovens with very strictly controlled temperatures and humidity. The kiln drying process can remove approximately 93% of the wood's moisture.
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.
quality doesn’t come cheap, but a good-quality sofa will stay more comfortable and retain its looks for a long time. Consider buying the best quality that you can afford.
