What the work is
A body of industrial furniture design defined by injection-moulded plastic objects—including the first single-mould chair (1968), the Componibili modular storage system (1969), the first fully injection-moulded plastic table (1982), and a marbleized plastic arm lounge chair (1988).
How it was made
Anna Castelli Ferrieri used injection moulding to produce furniture in single, seamless pieces—first with a chair in 1968, then Componibili units in 1969, a fully plastic table in 1982, and a marbleized plastic arm lounge chair in 1988.
What works
Componibili units are flexible, functional, and practical—and remain among Kartell’s best-selling items decades after launch.
What does not
The sources do not establish any failure, limitation, or criticism of her work. No claims are made about ergonomics, durability, cost, scale limits, user reception beyond sales, or environmental impact.
What it influenced
She influenced the adoption of plastics as a mainstream design material and established Kartell’s foundational aesthetic: geometric shapes, bold colour, and highly polished finishes.
Is it worth your time
Yes. Her work demonstrates how material constraint—plastic’s fluidity and repeatability—can generate enduring functional forms without ornament or compromise.
