Why we love this collection

Dressed Lines Coordinates Collection

Mid-century minimalism, dialed to the maximum. Dressed Lines Coordinates™ is crafted for the ultimate in definition and texture. And while you’d normally have to wait months for us to extend a collection, that hardly seems fair. These designs are here today, ready to transform lobbies into announcements, seating areas into dens. Pair with the core Dressed Lines™ collection, flip between cream and black bases, or set your own destination.

Knot A Problem II

With precise patterns that command attention, Knot A Problem™ is bold enough to make a statement—its lines and dots rippling and meandering through your space.

Available with a Cream (I) or Black (II), each the reverse of the other.
