Leucos invited David Rockwell to reimagine the Stacking Collection

14 April 2023

The existing collection, composed of three floor lamps made of handblown glass cylinders of different colors and sizes, is now joined by a series of striking new horizontal chandeliers and vertical pendants


Under the new direction of Abramo Manfrotto, Leucos invited renowned architect David Rockwell to reimagine the Stacking Collection, which he originally designed in 2007. The same concept influenced the Stacking collection, will be presented in Milan at EUROLUCE. The iconic Stacking lamp will be redefined with new models and colors: a horizontal pendant version offered in two sizes, and three vertical pendant lamps with the option for a wall application.

Designed in 2007 by David Rockwell, Stacking is a human-scale floor lamp inspired by traditional Japanese lacquered stacking cups. It is comprised of individual hand-blown cylinders of colored glass that can be stacked to form a radiant, atmospheric column. These glass modules were made with a traditional Venetian handblown glass technique called “incamiciato” (Italian for “jacketed” or “layered”), where a Maestro glass blower uses multiple layers of glass, each of different transparencies and properties. This labor-intensive technique has brilliant results, as it allows for different tones and opacity in each module. Assembled into each other, the cylinders result in chromatic overlays propagating light in a sophisticated way.

Stacking was offered in three distinct color combinations using multiples of amber, tobacco, white, fume, orange, and mirrored glass. Stacking represents a bestseller for Leucos. Its timeless design and originality also became one of David Rockwell’s favorite products, earning a place of pride in his studio office.

Leucos decided to evolve the legacy of Stacking and invited David Rockwell to design more lighting elements to enhance the existing collection. Contemporary techniques have been used for the new pendant lamps that nod to artisan traditions and the original Stacking floor lamps. The lighting fixtures include a set of horizontal pendant lamps in three sizes and three vertical pendant lamps with the option for a wall application.

The modular glass cylinders are now slightly narrower than the original collection for a more delicate, refined look. Vibrant color combinations were inspired by mid-century Murano glass and are interspersed with elements in contemporary metallic finishes, creating graphic dynamism. The horizontal luminaires feature metal end caps, and dimmable LEDs offer the possibility of creating a more direct or softer light, depending on preferences.

Drawing upon the studio’s extensive experience with lighting design for theater, hospitality, retail, and restaurants, Rockwell Group has now transformed Stacking for a variety of uses and environments, allowing designers to combine and create their own compositions in a modular and flexible way.

“Stacking is one of our most successful products. Its timeless design is captivating and suitable for a multitude of environments in residential settings, as well as corporate and hospitality. Transforming this product, originally imagined for floor use, into a suspension, was no easy task. David and his team did an incredible job and as soon as we saw the early sketches, we knew we had a masterpiece!” says Abramo Manfrotto, CEO of Leucos.
