Not with 100 percent certainly, but a lot better than some staged photos on a website.
Most retail furniture stores in the US (Blu Dot, Room and Board, West Elm, Herman Miller, Vitra, Knoll, Steelcase, etc.) either design their own furniture in-house or have name-brand designers (e.g. Eames, Jasper Morrison, etc.) they collaborate with. (Sometimes the manufacturer also produces their own "generic" white-labeled versions; for example, the factory that makes Knoll sofas apparently also makes identical/near-identical no-name sofas that are sold under different brand names at much, much lower prices, and if you have some inside information you can find out where to get these.)
Then there are high-end retailers like DWR, YLiving, Lumens, etc. that are more like Amazon in that they mostly don't rely on white-labeling.
