Dealer version .24


Design 2021 - Massimo Bianchi

The versatility of the 1927 project of Charlotte Perriand for his Parisian apartment in Place Saint-Sulpice inspires this family of chairs with adjustable back. Extendo re-interprets it, designing a version with arms that allows full rotation under the table top, facilitating accessibility and seating.

Chair / Chair with armrests / Stool / Outdoor use

The versatility of Charlotte Perriand's design in a seat with high technical content.

A modern and essential line with great dynamism.

The seat with a lumbar position backrest is certainly a compromise in terms of comfort compared to the armless version. The priority for those who choose this version with a backrest lower by about 11 cm is the great usability resulting from the rotation of the backrest under the tabletop.

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.

ECH9 is available with armrests,
without armrests, or in the stool version.

Designed to rotate under
every EXTENDO table.

The swivel version of ECH9 with armrests has a backrest line with lumbar support, therefore lower by about 11 cm. than the armless model. Deliberately lower so that during rotation, it can pass under the EXTENDO tabletops. This feature allows for easy sitting and standing 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 the color palette of the various base materials, tops, and seats, you can discover the wide range of possibilities offered by our designers.
