Dealer version .24


Design 2021 - Massimo Bianchi

The revolving version of ECH4 has the same structure with small cross-section steel profiles, in which the four spokes converge in the revolving connector. The chairs with arms have a height that allows their full rotation under the table top. The adjustable backrests are available for the chairs with or without arms.

Chair / Chair with armrests / Stool / Outdoor use

A versatile and functional design suitable for any environment.

The ECH5 collection is the swivel variant of the ECH4. ECH5 reintroduces the technology of curved steel wires welded at points, of which the Eames were great pioneers in the 1950s with the “Tour Eiffel” seat base.

Adaptive backrest for maximum comfort.

The backrest with flexible movement adapts to the ergonomics of people with different builds and postures, resulting in comfort and coziness.
A mechanism with a special spring is the pivot 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.

ECH5 is available
with armrests, without armrests, or in the stool version.

Designed to rotate under every EXTENDO table.

The swivel version of ECH5 with armrests has a backrest line with lumbar support, therefore about 11 cm. lower than that without armrests. Deliberately lower so that during rotation it can pass under the EXTENDO table tops. This feature allows you to sit and rise easily without moving the seat backward.

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.
