Why do my Series 7 chairs break or come loose?

In 2002, the Fritz Hansen Series 7 chair production was changed. Instead of a wooden mounting plate, which is glued to the seat, it was replaced by a plastic plate. These plastic plates come loose after a period of time because the glue does not adhere well to the plastic, and the plates tear due to use.

How do I repair your the Fritz Hansen chairs?

The Series 7 chairs will be refurbished with a new wooden mounting plate. The wooden plate and glue are specially made, based on years of development and material testing. This is done in my workshop, for antique furniture restoration, based in The Netherlands, The Hague, founded in 1996.

Should I repair or buy new Series 7 Fritz Hansen chairs?

ReNewing the Series 7 chairs is worthwhile because they will still last for years and are far from worn out. The average repair cost is €135 per Series 7 chair. And that’s much cheaper compared to buying a new Fritz Hansen Series 7 chair, which costs around €450. If I repair all your chairs at once, I can reduce the cost for you. The more chairs you have me glue, the higher the discount per repaired chair.

The repair is definitely worth it. In addition, restoring the chairs is a sustainable choice, preserving resources for our planet.♻️

Evolution of the fastening method

Left: wooden plate, used until the end of 2002

Middle: plastic plate used in current production

Right: The new wooden plate. Produced in-house with better adhesive properties and unbreakable.

The use of the plastic plate since 2002 is the reason why the seat comes loose from the base. I never receive chairs with a wooden plate from before 2002, so that system still works to this day.

Gluing the wooden plate

The wooden plates are glued with clamps under high pressure until curing is achieved after 24 hours.

Fix all the Series 7 chairs?  Or only the broken ones?

This video shows how easily other chairs come loose after the first one has come loose, because the plate is no longer really attached, and is likely to come off easily in the near future, actually some of my clients show remorce when they only had one chair repaired and the next failed thereafter shortly.

The majority of my customers decide to have all Series 7 chairs glued, it saves them travelcosts and piece of mind.

Repairing a broken Series 7 chair yourself : A Cautionary Tale

Many of my customers have tried repairing their Series 7 chairs, using the plastic plate that came loose from the seat. They’ve experimented with various types of glue, such as araldite epoxy resin, polyurethane glue, hot melt glue, super glue, fast-set urethane adhesives, and sealants. Some even added bolts and screws. Unfortunately, all these methods have yielded poor results because the bonding qualities are inadequate.

The reality is, you can’t effectively repair the chair using the original plastic plate. Commercially available glues can’t hold the cracked plastic to the wood, and the already damaged plate will eventually break again. Did you already notice the white crack lines in your plastic plates? Along these lines is where the plates will break once you try to glue it again.

That’s why I developed a wooden replacement. More durable, stronger, and repairable. But a plate alone isn’t enough. The adhesive I use is made to do the job — even when the cleaned surface under the seat is uneven, it still creates a solid bond with the new wooden plate.

This combination — wood and glue — gives a lasting solution. And that’s not just a claim: out of over 1,000 chairs I’ve repaired, not a single one has come back with the same issue.

No. 3107, The Sevener, No. 7, 1955
Arne Jacobsen Fritz Hansen

In 1955, four years after introducing the iconic Ant chair, Arne Jacobsen unveiled another timeless masterpiece for Fritz Hansen: the No. 3107, more famously known as the Sevener. While the Ant was bold and distinctive, the Sevener struck a balance—its sleek silhouette was more universal, instantly resonating with a broader audience. With its elegant, slightly larger seat shell and a backrest wide and tall enough to lean an arm on when sitting sideways, the chair offered both beauty and comfort.

Designed for versatility, the Sevener found its place everywhere—from stylish private homes to refined public institutions and dynamic workplaces. Its stackable design and optional brackets for row setups added practical appeal. But its true magic lies in the illusion it creates: the seat shell appears to float, thanks to its slim, gleaming legs that reflect their surroundings like light sculptures.

This sculptural feel is also deeply tied to the material. The chair’s characteristic narrow waist wasn’t just an aesthetic choice—it was a technical necessity that enabled the plywood to bend gracefully in three dimensions. The seat’s gentle springiness, enhanced by rubber inserts between the shell and frame, brings a quiet comfort to its form.

Jacobsen’s visionary use of plywood was sparked by his admiration for the work of Charles and Ray Eames, whose designs he encountered during a trip to the United States. That inspiration, paired with Jacobsen’s Nordic design sensibility, resulted in what would become his most celebrated chair model.

Today, the No. 3107 / Sevener remains a global design icon—over 7 million sold since 1955, and still counting.
