When Fashion meets Interior Design. Apartment 415 was established in 2009 by the Agustin Sanders, a Mexican/San Francisco based interior designer.  As creative director behind apartment 415 he brought to life an innovative and fashion forward pillow brand that would merge the glamorous world of fashion with the lustrous realm of Interior Design.  The 415 number of the brand is not only San Francisco's area code but it's also the apartment number to Agustin's design studio in San Francisco’s Nob Hill, where he designs all of his work.
