Vintage Black Leather Swivel Office Chair ‘Mondo’ by Karl-Erik Ekselius for JOC, 1960s.

This striking swivel chair by Karl-Erik Ekselius for JOC Vetlanda is a refined example of Scandinavian modernism, combining comfort with understated authority. Designed in Sweden during the mid-20th century, the chair features beautifully aged black leather upholstery paired with a sleek steel frame on castors, giving it both visual lightness and practical mobility.

Ekselius was renowned for designing seating that balanced ergonomic comfort with clean architectural lines, and this chair is no exception. The generous seat, supportive backrest and smooth swivel action make it ideal as a desk chair, studio piece or statement chair in a modern interior. Its timeless palette and honest materials allow it to sit comfortably in both contemporary and vintage-led spaces.

✨ Restoration Details

The leather has been professionally cleaned and preserved using a moisturizing leather balm and wax to nourish and protect the surface while retaining its natural character. The steel frame has been carefully cleaned and polished with a metal polish, restoring its subtle sheen without over-refinishing.

📌 Condition

Excellent vintage condition. The leather is supple and well cared for, showing only light, age-appropriate wear consistent with its history. The steel frame is clean, solid and structurally sound, with smooth swivel movement and fully functioning castors.

🧡 Why It Stands Out

This chair perfectly captures the moment when Scandinavian design began to embrace a more industrial edge, pairing soft leather with crisp steel in a way that still feels relevant today. Its versatility is a huge part of its appeal — equally at home behind a desk, in a reading corner or as a sculptural accent piece. Designed by one of Sweden’s most respected modernist designers, it’s a piece that offers comfort, character and enduring design credibility in equal measure.
