The most iconic products Greta Grossman designed in the 40's and 50's were the Gräshoppa floor lamp and the Cobra floor and table lamps. Grossman was highly influenced by European Modernism, which had been imported to the US by influential architects, such as Walter Gropius (founder of the Bauhaus) and Ludwig Mies van der Rohe. Grossman, in turn, played a significant role in defining the aesthetic of mid-century Californian Modernism. Today, Grossman's product designs are highly collectible and are sold at auctions all around the world. Grossman's products are unique, modern classic designs.

Cobra's tubular flexible arm can be bent in all directions while the shade can be rotated a full 360º. The base is covered in powder-coated aluminium and weighted with a cast iron ballast.
