Postmoderna's permanent collection is divided into four subcategories: Skateboarding, Urban Knitting, Parkour, and Cultural Diversity. The “Skateboarding” subcategory aims to capture this fluid urban experience for which Stockholm is heaven, with some 10 skateparks (and counting). “Urban Knitting” is carried out by creative Stockholmers who take a warm-hearted and colorful craft out of its domestic context and bestow it to the prosaic street. “Parkour” is an emerging urban experience that takes the whole city as its playground—what is a mundane stairway for ordinary citizens is a challenging obstacle for traceurs (practitioners of Parkour). The subcategory entitled “Cultural Diversity” intends to showcase the ways in which elements of the built environment aid the preservation of ethnocultural diversity, and the creation of the experience of a peaceful togetherness in Stockholm.

This subcategory presents the following 9 exhibits which may be found in 8 locations in Stockholm:
