Filamento Vertical Suspension by Astep

A single line of light hung from the ceiling: the Filamento Vertical Suspension turns a borosilicate glass tube and an aluminum body into a slim, sculptural presence.

Designed by Mayice Studio for Astep, it comes in three lengths (41, 79 and 104 cm) and two glass configurations at 41 cm, so it can hang alone over a console, in a row down a stair, or in a staggered cluster.

“Filamento sprung from the observation of how light passes through glass.” — Mayice Studio

Best for

Stairwells, entries, dining tables, bedsides and reading corners where a vertical line of light adds height and rhythm.

Who this is not for

Anyone who needs bright general lighting from a single fixture. Filamento is a sculptural accent, so combine several or add task lighting.

Why we carry it

We have been curating design-led pieces since 2009, and Filamento is the kind of lighting we look for: architectural, quiet and built around one honest idea. It comes from Astep, the house founded by Alessandro Sarfatti, whose family helped define modern Italian lighting.

Buy once: durability and care

Keep the fixture indoors and dry. Disconnect power before cleaning, then wipe the glass and aluminum with a soft, dry or lightly damp cloth and dry thoroughly. Bulbs are not included, so use the lamp type and wattage listed above.
