This is because the brand owner chose not to print or affix any logo or trademark on the bed frame during the design and manufacturing process. This situation is also common in some household products on the market, and it does not necessarily mean that the product is faulty or substandard. Bed frames of different brands and models are designed and manufactured in different ways, and the presence or absence of logos or logos is not necessarily related to the quality and performance of the product. If you have any doubts about the quality or source of the bed frame, you can consult the seller or manufacturer, or check the relevant certification and regulatory information.
