Designed in 1965 by the Danish duo Preben Fabricius and Jørgen Kastholm for Alfred Kill International, the FK6725 — often referred to as the “Tulip” Chair — is a sculptural icon of mid-century minimalism. Combining German industrial rigor with Danish modernist purity, the chair embodies a rare harmony between engineering and elegance.

Manufactured by Walter Knoll, the chair features a sculptural fiberglass shell that offers both comfort and a sense of lightness. The shell is covered in white leather, adding a touch of luxury while maintaining the chair’s clean, streamlined look. It is supported by an elegant aluminum tripod base, which gives it a distinctive architectural presence.

This particular piece, remains in good original condition, showing only minor signs of wear that are consistent with its age. The white leather upholstery is clean and free from any rips or tears, with just a few small surface scratches that do not detract from its overall appearance. Similarly, the fiberglass shell is structurally sound, with the lacquer exhibiting some minor scratches, typical for a chair of this vintage. Despite these subtle signs of use, the chair retains its strong form and iconic design, making it a striking addition to any modern interior. A testament to the enduring quality of mid-century craftsmanship, this FK6725 Tulip Chair is both a functional piece of furniture and a collectible work of design history.
