Dealer version .24


Design 2021 - Massimo Bianchi

The light design is the result of the steel profiles with reduced cross-section that form the frame: 6/12 mm for the four spokes braced by tie-rods that stiffen the structure. The adjustable backrests and removable fabric upholstery seats of the chairs are available in versions with or without arms.

Chair / Chair with armrests / Stool / Outdoor use

A light but rigid steel structure inspired by great masters.

Perfect balance
between form and material.

ECH4 is inspired by a project by the Eames, an icon of 1950s design, consisting of a wire mesh welded at points. The seat base is a lightweight but extremely rigid structure, and for this reason, the project is called “Tour Eiffel”. The result is a seat with a powerful technical and modernist suggestion.

Adaptive backrest for maximum comfort.

The backrest with flexible movement adapts to the ergonomics of people with different builds and postures, resulting in a comfortable and welcoming experience.
A mechanism with a special spring is the fulcrum of the backrest movement.

Fabric padding completely removable.

The chair is available with fabric upholstery in the practical removable version. It’s a great solution to give you the opportunity to wash the upholstery or replace it over time. Both the seat and the backrest can be requested in the removable version.

ECH4 is available with or without armrests,
always with the adaptive backrest.

The perfect pair.
ECH4 and T11 table.

The lattice frame concept is also extended to the ECH4 chair, where the tension and compression force lines run along the thin steel profiles.
The 3D tube bending technology used in the ECH4 chair is essential to achieve fold lines that have the same aesthetic language as the table base. A table and chair combination that enhances the project as a whole.

Interchangeable feet
with a click.

Each seat includes a double kit of interchangeable supports: a felt kit for wooden, resin, and ceramic floors, and an additional Teflon kit for carpets and rugs. The foot is composed of a pre-inserted part and an interchangeable part with snap-in fixing.

Thousands of combinations.

Each EXTENDO table or chair collection is configurable in dozens of combinations. By mixing and matching the color palette of various base materials, tops, and seats, you can discover the wide range of possibilities offered by our designers.
