The use of furniture in life I think everyone knows that good furniture is for you who understand life better, but do you know how to look at the quality of furniture? Today, Jiuzheng Building Materials Network Xiaobian will tell you about which aspects to look at. The quality of the furniture is good or bad. To buy furniture, you must first understand the seven key points of furniture. 1. Like cabinet furniture, we can see if the cabinet structure is loose, the joint parts are not firm, and there are broken and broken materials. 2. If the wood moisture content of the furniture is high, and the interior of the furniture uses decaying wood or wood that the insects continue to erode, then this is also a poor quality furniture. We must not choose such furniture when buying furniture. 3. When buying furniture, it is necessary to look at the materials used. The quality of the furniture is seriously unreasonable. For example, the use of particle board, medium-density slats for the door edge of the wardrobe, and the load-bearing parts of the column cannot be selected. 4. Furniture with glass should pay attention to whether the glass slab is made of nails. If it is, it is not good furniture, because the furniture made of nails can easily cause glass breakage and endanger personal safety. 5. How to look at the quality of furniture when buying furniture? See if the functional size of the furniture meets the requirements of the standard. For example, the height of the hanging space of the large wardrobe is not as good as 1350mm, and the depth is less than 520mm. Wait. 6. Look at the quality of leather furniture. The interior wood of the sofa is high in moisture, the board is thin, the bark is used, and the furniture using the splitting material, the decaying material and the worm material is not good furniture. 7. If it is frame furniture, it should also pay attention to whether the structure of the furniture is made of nail structure. If it is not open, not eye-opening, no glue, loose structure, and weak furniture, it is a bad quality furniture. When buying furniture. Never buy this type of furniture. .
