What's the difference between a built-in wooden frame sofa and a built-in metal frame sofa?
This technique is only used in the Royal Furniture of Italy. Although the price will be more expensive than the solid wood frame, but in terms of quality, sitting feeling is excellent. Therefore, we buy sofa in the product, for their own health problems to consider, or pay attention to the benefits of the product itself and quality is better. Today, society stresses the healthy, comfortable and environmentally friendly life. So, consider your own life, or choose a metal framework. Of course, the sofa itself or to buy the built-in independent with the spring, because within Dangdang sponge and filled with cotton to fill the sofa cushion for two years will be deformed, with a spring with independent words is not only a good degree of elasticity, and no deformation. Therefore, I hope the majority of consumers do not seek cheap, long-term use and healthy life is the most important.
The sofa with built-in solid wood frame has some defects in itself. In wet weather, solid wood frame in long-term contact with moist air will lead to solid wood mildew, in the south, the relative humidity of the air, more prone to such a situation. Solid wood once moldy, it will produce bacteria, fungi and other harmful substances. People pose a threat to the body in their long-term use. And the quality of the product will be shortened. This is a loss for consumers. If the density board to do the framework, then not only in mildew will be harmful, and in the air is harmful, because the density board will evaporate, formaldehyde and other harmful gases, and easy expansion, cold contraction. Although the price will be much cheaper than the built-in steel frame, but in a comprehensive comparison. It's not worthwhile.
A sofa with a built-in metal frame is just the opposite of a solid wood frame. The sofa with the built-in metal frame is not only more stable in structure, but also can not cause mildew, and can not pose a threat to the human body during the long-term use. Nowadays, sofas with built-in metal frames are rare in the domestic market. Because it's a high-end process.
