Why we love this collection

Granite Mountain Collection

Granite is one of the hardest substances in the world, but even this seemingly immovable force bends to the power of nature–with beautiful results. Likewise, our biophilic-inspired Granite Mountain™ Collection visually translates this natural balance between strength and beauty. Add You’re So Vein™ from FLOR® to these eight modular styles for a perfect, marbled companion.

Flat Rock

Flat Rock™ carpet tile offers a heightened texture for companions Rock Springs™, Mantle Rock™ and Rockland Road™ to transition.
