Formani

Dutch precision, designed.

Formani is a Dutch hardware manufacturer producing lever handles, escutcheons, cabinet pulls, and bathroom accessories. Founded in the Netherlands, the company works with a focused group of designers — among them Piet Boon, Bertram Beerbaum, Osiris Hertman, Edward van Vliet, and the office of Gensler — each briefed to develop a total concept rather than a single product.

The result is a catalogue of coordinated systems that move across doors, windows, furniture, and bathrooms without visual interruption. Finishes — including satin stainless steel, PVD satin black, bronze, PVD satin gold, and polished stainless steel — are shared across collections, so a lever, a cabinet pull, and a towel bar can arrive at a project from the same material palette.

Every piece is precision-welded in the Netherlands and designed to work with both European mortise and North American tubular latch systems. Formani hardware is built to sit flush, return cleanly, and remain legible at the scale of a room.

Principles

Complete Concepts: Each Formani collection spans door levers, escutcheons, cabinet hardware, and bathroom accessories — one design language across every contact point in a space.
Designer Collaborations: Collections are developed with named designers including Piet Boon, Bertram Beerbaum, Osiris Hertman, and Gensler, each producing a coherent formal system rather than individual objects.
Finish Consistency: All finishes — satin stainless steel, PVD satin black, bronze, PVD satin gold, and polished variants — are available across collections, enabling a unified material palette on a single project.
Dual Compatability: Hardware is engineered for both European mortise and North American tubular latch configurations, with explicit backset and door-thickness specifications provided for every product.
