Very Rare Pair of Mats Theselius Rattan and Steel Armchairs for Ikea

Although prolific Swedish architect and designer Mats Theselius moves freely between creating furniture, lighting, objects, installations, exhibitions, set designs, and more, he is perhaps best known for his innovative armchairs. Described by critics as “surprising and ingenious,” Theselius is responsible for some of the most noteworthy furniture designs of the 1980s and 1990s.

Born in 1956 in Stockholm, Theselius attended the city’s prestigious Konstfack (University of Arts, Crafts and Design), where he studied Interior Architecture. After graduating in 1984, he worked at various architecture firms in Stockholm.

In 1985, Theselius debuted a cylindrical club chair upholstered with elk leather. The chair’s unique, molded curved frame, which served as a backrest and armrests, became a signature design characteristic of many of Theselius’s seating pieces. He partnered with entrepreneur Sven Lundh, and Lundh’s company, Källemo, produced a limited-edition variation of this seat, the Älgskinns­fåtöljen chair, in 1991. The Iron/Suede lounge chair followed in 1994.

Another iconic Theselius piece is the National Geographic bookcase. Made of beech with glass doors and brass detailing, the bookcase features shelves sized to accommodate 25 years' worth of National Geographic magazines. For its debut in 1988, Theselius painted the bookcase the same recognizable yellow color that typically frames the cover of the publication.

While working on furniture design and other projects, Theselius served as a professor at the HDK – Academy of Design and Crafts at the University of Gothenburg from 1995 to 1996. He has also collaborated with several well-known Swedish and European manufacturers in addition to Källemo, including String, Marrakech Design, Minus-tio and David Design.

Throughout his career, Theselius’s works have garnered critical acclaim and won numerous awards. Among them are the Red Dot Design Award, the Torsten and Wanja Söderberg Prize, the Wallpaper Design Award and the King of Sweden’s Prince Eugen Medal (2018). Theselius also received the Bruno Mathsson Award in 1997, which is named for the revered Swedish master cabinetmaker. Theselius is said to have created his coveted Bruno armchair immediately afterward.

Today, Theselius’s pieces can be found in the permanent collections of the National Museum in Stockholm, the State Russian Museum in Moscow and the Danish Museum of Art and Design in Copenhagen.

IKEA is the world's largest furniture retailer, but its origins were far humbler than its global footprint suggests. Founded in 1943 by 17-year-old Ingvar Kamprad in the Swedish village of Älmhult, the company began as a mail-order business selling pens, wallets and picture frames. It wasn't until 1948 that the IKEA catalog started featuring furniture, altering the course of modern domestic design.

IKEA is rooted in democratic design, or the belief that well-made, beautiful objects should be accessible to everyone. This philosophy took shape in the 1950s when IKEA began working with independent designers to develop its own furniture lines. The pivotal innovation came in 1956, when IKEA introduced flat-pack furniture, a practical solution born out of necessity when designer Gillis Lundgren removed a table's legs to fit it into a car. This single insight reshaped how the world thinks about manufacturing, shipping and the relationship between consumer and object.

The 1970s and 1980s are now widely considered the golden age of IKEA design, a period when the company regularly collaborated with outside designers before transitioning to entirely in-house production. These decades produced some of the brand's most collectible pieces, and vintage examples are today actively sought after by collectors worldwide. Karen Mobring's safari-influenced seating — including the Diana, Natura and Amiral chairs — captures the organic, relaxed spirit of the era, while Noboru Nakamura's Bore chair and Lundgren's Pixi lounge chair round out the most coveted 1970s offerings. The 1980s brought a sharper, more industrial sensibility through Niels Gammelgaard's work in wire and tubular steel, among them the Enetri shelf, the wire Jarpen chairs and the foldable Ted chair, as well as Tord Björklund's Skye chaise and Klinte armchair.

Beyond these core collaborators, IKEA has worked with some of the most significant names in 20th-century design. Kai Kristiansen, Ettore Sottsass, Verner Panton and Mats Theselius all produced pieces for the brand, and rare examples of their IKEA work are among the most prized finds for collectors today. More recently, collaborations with designers such as Ilse Crawford, Tom Dixon and Hella Jongerius through its IKEA PS (“post scriptum”) collections have continued to push the brand into more expressive territory.

IKEA has also shaped retail culture itself. Its sprawling, maze-like store format — introduced in Älmhult in 1958 — transformed shopping into an experience, complete with room vignettes, a Swedish café and a one-way path designed to inspire. The brand has since expanded to more than 60 countries, while its annual catalog, once one of the most widely distributed publications in the world, became a cultural artifact in its own right.

IKEA continues to balance its founding tension: mass production in the service of good design. As Kamprad once put it, "to design a desk which may cost $1,000 is easy for a furniture designer, but to design a functional and good desk which shall cost $50 can only be done by the very best."
