When it comes to bespoke
3D furniture modeling, the first step is always a concept. Manufacturers generally offer only a CAD drawing or a hand sketch, but they may also provide a product prototype that is the most accurate representation of all.
However, it is not required that every shot include a person or people. For a product design 3D modelling project, a photo of furniture, a regular view in one shot with no cropping, and a few different angles will also do.
