Plywood is dry and light. During the manufacturing process (pressing under high temperature and pressure) of it evaporates all the moisture - plywood never lead and never rassohnetsya. Depending on the design, the frame can be made from a combination of plywood and wooden beams (bearing part) or just out of plywood. The only exception is a detail frame 3-seat sofa - the bottom bracket. Its length is usually about 2m. A basic standard size plywood, adopted in the CIS, is 1.5 meters long side. Even a good producer is forced to put in this place particleboard. Than thicker plywood, the higher the strength of the skeleton.
Unfortunately, the price also increases. Minimum thickness is 12 mm. Maximum - 25 mm. If the frame is made of thicker and more expensive plywood, you must tell about it. High performance characteristics of plywood enables manufacturers of quality furniture to give a guarantee on frame and 10 years. If your weight - 120 kg, has a reason to pay attention to the frame of plywood not less than 16 mm. It is important that in the manufacture of the frame was only used The dried wood (moisture content 8%).
Raw frame will be dry in your home, and when it finally dries, begin to squeak. Well dried timber is at least two to three times more expensive than 'Crude'. Very often the manufacturer (and not just domestic), saves and uses unseasoned material. Attach the hand to open parts of the frame (if there) and hold a few seconds.
