Treflo Round Glass
Made by Cassina
Designed by Erwan & Ronan Bouroullec
Treflo arrives at simplicity through discipline. Its round silhouette reads as immediate and direct, yet the base demands a level of manufacturing precision that few producers can sustain. Formed from rigid polyurethane enriched with polyols derived from biological sources, the base achieves its fluid, sinuous geometry through thermoforming techniques refined over decades at Cassina's Meda atelier.
An internal metal structure and cast ballast anchor the base invisibly, ensuring stability without interrupting the sculptural reading of the form. The table stands without visual noise.
The extra-clear tempered glass top is thermoformed and back-lacquered, bringing luminosity and depth. Its rounded edge softens the profile, creating a quiet continuity between base and surface. The result is a composition that rewards proximity, its material and structural logic becoming more apparent the closer one looks.

Frequently Asked Questions
What is the base of the Treflo table made from?
The base is formed from rigid polyurethane enriched with polyols derived from biological sources. It achieves its sinuous, sculptural form through thermoforming, with an internal metal armature and cast ballast providing structural stability from within.
What glass is used for the Treflo round top?
The round top uses extra-clear tempered glass that has itself been thermoformed, then back-lacquered for depth and luminosity. The edge is fully rounded, giving the profile a continuous, uninterrupted quality.
Where is the Cassina Treflo manufactured?
Treflo is produced at Cassina's Meda atelier in Lombardy, Italy, where the thermoforming techniques used for both the base and glass top have been developed and refined over decades. Cassina's in-house production allows for the tight tolerances the form requires.
How does the Treflo base achieve stability without visible support elements?
A concealed metal armature runs through the interior of the polyurethane base, paired with a cast ballast that lowers the center of gravity. This internal engineering keeps the exterior form entirely clean, so the sculptural silhouette reads without interruption.
Who designed the Cassina Treflo table?
Treflo is part of Cassina's ongoing exploration of advanced forming technologies, developed within the Meda atelier's tradition of collaborating with leading designers on structurally ambitious forms. Cassina has a long history of bringing technically demanding designs into production through its own manufacturing infrastructure.
