Why we love this collection

Human Nature Collection

As designers we know that when we follow nature’s example, designing spaces that ignite our senses through light, color, texture and detail, we also spark the creative spirit in each of us. The Human Nature Collection was designed as a beautiful foundation for those spaces, made up of ﬁve different modular carpet textures.

HN840

Borrowing from natural elements, HN810, HN850 and HN840 carpet tiles placed in sequence blend seamlessly in an organic movement that shows no hint of the corners or edges of the tile.
