Defying traditional chair construction, cantilevered designs create the illusion of weightlessness, relying on engineering and material strength to provide both comfort and support. First pioneered in the early 20th century by modernist visionaries, this innovative approach remains a hallmark of sophisticated design, balancing function with sculptural form. This week, we spotlight five cantilevered seating designs that push the boundaries of materiality and craftsmanship—each a study in both structural ingenuity and aesthetic refinement.
PK20
Poul Kjærholm
Designed by Poul Kjærholm in 1967, the PK20 lounge chair is a masterclass in refined cantilever construction. Its sleek, curved steel frame cradles a supple leather or woven rattan seat, demonstrating Kjærholm’s signature approach to material-driven elegance and effortless comfort. Over the years, the PK20 has become a classic – as well as a permanent fixture at the Victoria and Albert Museum in London.
ARMCHAIR 400 "TANK"
Alvar Aalto
Originally designed by Alvar Aalto in 1936, the Tank chair reimagines cantilevered construction through a bold, sculptural lens. With a wide stance and generous proportions, this design pairs the natural flex of bent birch wood with luxurious upholstery, offering a rare blend of comfort and architectural presence. Birch frame available with clear lacquer, black lacquer, walnut stain, or honey stain.
INGO
Mats Theselius

Designed with a strikingly minimal steel frame, the Ingo chair from Källemo embodies the essence of cantilevered design—reducing visual weight while maximizing support. The gently suspended seat and backrest, upholstered in riveted saddle leather, create a sense of movement, offering a dynamic seating experience that feels effortless yet grounded. Steel frame available in chrome, matte chrome, copper, black oxide or brass. Multiple leather options available.

SNAKE CHAIR
Poul Henningsen
A true statement in design, the Snake Chair from PH Furniture takes the cantilever concept to an expressive extreme. The continuous frame flows seamlessly from base to seat to backrest, creating an uninterrupted form that showcases the balance between movement and stability. Upholstered leather seat available in black, walnut, red, mocha, or natural.
SYSTEM 1-2-3 LOUNGE
Verner Panton
Designed by Verner Panton in 1973, the System 1-2-3 Lounge Chair is a bold expression of the cantilevered form. Its fluid, single-line frame eliminates traditional legs, creating a sculptural silhouette that appears to float. The gently curved seat contours to the body, providing both comfort and a striking visual presence. Available in a variety of upholstery options, this piece embodies Panton’s visionary approach to form and function.
