Armchair
Sculptural furniture / Seating design • Gunnar Aagaard Andersen (Danish, 1919–1982)

Style & Movement
Mid-Century Modern / Bio-morphism / Proto-Pop / Danish Design
Medium & Technique
Poured liquid polyurethane foam that hardened into a self-supporting structure; chocolate-colored pigment.
Creation Period
1964
Dimensions & Format
Approximately 75 x 110 x 95 cm; Organic, free-form volume.
Subject Description
The armchair is a radical departure from traditional furniture construction. It features a bulbous, organic, and amorphous form that appears to be melting or oozing like viscous liquid. The composition lacks internal skeletal framing, relying entirely on the density of the polyurethane layers to maintain its shape. Its dark mahogany-brown color evokes geological or biological matter.
Condition & Value Assessment
Condition Assessment
Very Good (Museum Grade); The material is inherently unstable over decades, but this specific example appears well-preserved with intact structural integrity and minimal visible surface crumble.
Estimated Market Value
$40,000 - $60,000 USD for an original 1960s specimen.
Auction Estimate
$30,000 - $50,000 USD
Provenance History
Gift of the designer, 1966. Likely documented through the Museum of Modern Art (MoMA) collection or a similar major international design institution as indicated by the museum-style display and wall plaque.
Art Historical Significance
This piece is a seminal work in 20th-century design, representing the first use of polyurethane foam as a primary structural material for furniture. It challenged the functionalist 'form follows function' dogma of the era, introducing an expressive, almost surrealist aesthetic into domestic objects. It is included in the permanent collections of MoMA and the Vitra Design Museum.
Notable Features
The 'lava-like' aesthetic achieved by pouring layers of foam; the absence of a traditional frame; manufactured by Dansk Polyether Industri in Denmark.
Condition Issues
Polyurethane foam of this era is prone to oxidation, drying, and crumbling (off-gassing). Visible surface pitting and slight darkening of the pigment are common aging characteristics for this material.
Conservation Recommendations
Requires strictly controlled climate conditions (low UV, stable humidity, and temperature) to prevent the acceleration of polymer degradation. Should be handled with extreme care as old foam becomes brittle.
