Preben Fabricius & Jørgen Kastholm office chair

The office chair model BO-611 was designed by Danish modernists Preben Fabricius and Jørgen Kastholm and produced by Bo-Ex in Denmark. This piece exemplifies the duo’s refined approach to industrial design, where minimalist aesthetics are combined with ergonomic function and high-quality materials. Designed during the mid-20th century, the chair reflects the movement toward elegant, purpose-driven office furniture in modernist Scandinavian interiors.

The chair features a shell-form seat and backrest upholstered in smooth black leather. The leather has a glossy surface, contoured over a single molded form that curves gently to support the sitter’s back and body. The design emphasizes visual clarity and material integrity, with subtle ergonomic shaping that allows for comfort without the use of additional cushioning or ornamentation. The leather shows slight wear and soft creasing, which contributes to the chair’s vintage character without affecting its structural condition.

Beneath the seat is a three-legged base made of chromed steel. The legs taper outward and terminate in small caster wheels, allowing for smooth movement and rotation. The polished chrome contrasts sharply with the deep black leather, reinforcing the modernist palette of the piece. The base includes a central pivot connection that provides some flexibility in motion. The chrome surfaces display minor patina and light wear typical of age and use, maintaining an overall clean and presentable finish.

Preben Fabricius (1931–1984) and Jørgen Kastholm (1931–2007) were known for their collaborations throughout the 1960s, creating furniture that married Danish craftsmanship with architectural precision. Their designs often featured steel, leather, and minimal formal elements—qualities that positioned them at the forefront of Scandinavian modernism with a distinctly international appeal. The BO-611 office chair reflects these values, balancing simplicity, durability, and elegance in an everyday working context.

The dimensions are as follows: 60 cm wide, 48 cm deep, 72.5 cm high overall, with a seat height of 38 cm (23.6 x 18.9 x 28.5 inches, seat height 15 inches). The chair is in very good vintage condition, suitable for both functional office use and as a collectible design object in curated interiors.
