Warning 1: The definition of solid wood furniture is not standardized
Solid wood materials currently do not have a standardized definition in the industry. A type of imitation solid wood furniture is a mixture of solid wood and artificial board. Individual furniture dealers secretly changed the concept and promoted solid wood composite furniture as solid wood furniture. Even furniture with a layer of solid wood skin was also called solid wood furniture.
Warning two: panel furniture veneer Zhang Guanli Dai
The price of panel furniture is different due to different veneer materials. Nowadays, the veneers of panel furniture sold on the market are very realistic. It is difficult to see the difference in gloss and feel. Therefore, there are individual profiteers who use stickers, paint, etc. to pretend to be veneers to make the difference.
Warning 3: Fabric sofas are imported from China and imported
Some businesses take advantage of consumers' psychology and claim that their fabrics are imported products, so prices are expensive. However, some sofas are not real imported materials, but are made of domestic materials.
Warning Four: Mattresses are inferior
"Black Heart Cotton" frequently appeared in the newspaper, pushing the quality of the mattress to the top of the storm again, becoming a problem that consumers have to pay attention to.
Warning No. 5: The store ’s furniture qualification report is overdue
In some furniture stores, the product qualification reports presented by some brands have expired but are still displayed to consumers. This is itself a violation. The expired qualification report is invalid, so consumers should keep their eyes open before buying.
Warning Six: No instruction manual
Unlike those high-tech products, many consumers rarely pay attention to the instruction manual of the furniture when buying furniture, and some furniture manufacturers rarely provide product instructions. However, the instruction manual includes provisions on furniture materials, maintenance methods, and after-sales service. Therefore, the instruction manual is also an important link for consumers to understand the product and after-sales rights, and it cannot be ignored.
Warning 7: Mahogany furniture is not standardized
At present, the market is not standardized on the material of mahogany, and many illegal merchants use other wood to replace the precious mahogany materials to deceive consumers.
Warning No. 8: Abuse of green environmental protection concepts
At present, a few furniture dealers must say that they are green and environmentally friendly when selling furniture, and use the green and environmentally friendly signs to add color to themselves, but their products have not been certified at all. There are also some flooring manufacturers claiming that their flooring is zero formaldehyde, but according to relevant experts, natural wood itself contains very low formaldehyde, and the zero formaldehyde of processed flooring is simply impossible.
