Why we love this collection

Human Connections Collection

The Human Connections Collection is literally the intersection of the sensory cues that we seek to include in our fast paced lives, supporting the idea that the most positive spaces offer variability and choice. Eight different styles fit together in unique ways to create paths, intersections, collision zones and destinations. The highly patterned Rue and Stone Course complete the collection, offering a lively graffiti-like impact.

KERBSTONE

One of four textured styles in the Human Connections Collection, Kerbstone carpet tile recalls the look and feel of well-worn city streets.
