Plywood
Plywood, dry and light. During the manufacturing process (pressing under high temperature and pressure) of it evaporates all the moisture – plywood never lead and she never . Depending on the design, the frame can be manufactured from a combination of plywood and wooden beams (supporting part) or just out of plywood. The exception is only one detail frame 3-seater sofa – the bottom bracket. Its length is usually about 2m. A basic standard size plywood, adopted in the cis, is 1,5 m long on the sidelines.
Even a good producer has to raise at this point dsp. Than thicker plywood, the higher the strength of the framework. Unfortunately, the cost also increases. Minimum thickness is 12 mm. Maximum – 25 mm. If the frame is made of thicker and expensive plywood, you must tell about it. High performance characteristics of plywood enables manufacturers of quality upholstered furniture to give a guarantee on the frame to 10 years. If your weight – more than 120 kilograms, has a reason to pay attention to the skeleton of plywood not less than 16 mm.
Very important to the manufacture of the frame was used only dried wood (8% moisture). Raw frame will dry your home, and when they finally dry up, will start to creak. Well-dried timber is at least two to three times more expensive than the 'raw'. Very often the manufacturer (and not just domestic), saves and uses unseasoned material. Attach a hand to the open part of the frame (if any) and hold for a few seconds.
