It refers to a furniture concept that customers can assemble themselves. "DIY" is the acronym in English for "Do It Yourself," implying that customers take responsibility for assembling and building their own furniture instead of acquiring one pre-assembled by us.
DIY furniture often comes in the form of kits or packages that include all the necessary pieces, along with instructions to facilitate the assembly process. This option provides customers with a more interactive and satisfying experience as they participate in creating their own decor and furniture.
