The standard kit fits the most iconic models: the Series 7 (3107, 3207), the Lily (3101, 3208, 3108) and the Grand Prix (3130, 4130).
Got an Ant, a swivel base, or a Vico Duo? Make sure you mention it when you order — I’ll send a tailored kit with model-specific instructions, and will provide you a different kit in materials all together.

It can still be repaired. Send me a photo of the underside of the seat when you order. Upholstered models need a specific kit and adjusted instructions — skip that step and you’re making the job harder than it needs to be.

No. A floppy back means the 8 veneer layers inside the shell are separating — a process called delamination. That’s the original glue giving up after 4 decades, and it can’t be reversed. This kit is designed for seats that have come away from the base entirely, not for internal structural failure.

Before 2002, thats the closest I traced it back on workshop experience, Fritz Hansen used a wooden mounting plate. Chairs from that era are still holding tight today, we never see problems with those. After 2002 they switched to plastic — and that’s exactly why so many seats are now coming loose.

Standard adhesives don’t bond reliably to damaged plastic. By the time the seat lets go, the plastic almost always shows white stress fractures: the material is exhausted and will fail again quickly if you try to reuse it. This kit takes your chair back to the pre-2002 principle — a precision-machined wooden disc combined with an adhesive developed specifically for this joint. Stronger than the original factory bond. More than a thousand repairs. None have come back. It is a subtle repair and doesn’t impact the originality.

The instructions are inside the box – not printed on a loose sheet, but accessed via a QR code on a sticker on the inside of the lid. Scan it, enter the pincode printed alongside it, and you’ll land on a dedicated page with two things: a 13-minute video walkthrough on YouTube and a PDF you can read on a tablet or print on A4.

The reason for this setup: it means I can update the instructions whenever I improve the process, without a stack of outdated paper in circulation.

Yes. No drilling, no clamping, no sawing. The kit was designed for people who care about their chairs, not for carpenters. You get a clear video guide and written step-by-step instructions. A customer in Norway repaired six chairs in under two hours. You will scrape the old glue away, press out 4 ml of a prefilled syringe, place the new wooden disc, wait, and reassemble.

Everything you need for a complete, invisible repair:

→ Precision-machined wooden replacement disc with steel inserts
→ Pre-filled industrial adhesive syringe — single component, ready to use, no mixing
→ Sharp paint scraper — for removing the old mounting plate remnants
→ Access to a step-by-step photo guide and video tutorial

What do I need to have at home? You only need a screwdriver (suitable for your original screws: either an M6 x 10mm Phillips or a T30 Torx head) and a cloth. No extra or specialized tools are needed.

After reading the provided PDF and viewing the 14 min videoinstructions, around 15-20 minutes of active work per chair — scraping, gluing, mounting. The adhesive then needs 48 hours to cure fully before the chair is used again. Plan it for a moment when the chair can sit undisturbed for two days.

It makes the prep work slightly more involved than with factory glue. Rubbery adhesive from a tube can be cut away. Hard epoxy is trickier — you may need someone confident with wood, or an oscillating tool like a multitool, to cut it away without touching the wooden base.

Mention it when you order and I’ll give you specific guidance on what to do before you start.

No. A seat that’s separating from its base can let go completely and without warning — including under the full weight of an adult. That’s a structural safety risk, not just an inconvenience. Repair all affected chairs at once. The mounting plate on every chair of the same age has been exposed to the same wear. If one has gone, the others aren’t far behind.

Blame the design, not the guest — once the original adhesive starts letting go, it was never a question of if, only which chair goes first.

Extremely small. Out of over 1,000 repairs completed with this kit, only twice did something go wrong — and both times the customer was back on track with a short explanation and fresh materials.

The instructions guide you through every step: a detailed PDF and a 13-minute video that walks you through the process hand in hand. Take your time, follow the steps in order, and don’t rush the adhesive. That’s really all it takes.

And if something unexpected does happen — I’m here.

It happens. If you repaired one chair and set the rest aside, the adhesive in the remaining syringes will have cured inside the tube by the time you return to them – that’s just the nature of a reactive glue without stabilisers.

You can order a refill of three syringes for a small fee covering materials and a contribution toward shipping. That’s enough adhesive to complete the remaining chairs in your set. Get in touch directly – by email or WhatsApp – and I’ll sort it out for you.

The kit price covers materials, packaging, the scraper and shipping and handling costs. With one kit, you carry those costs in full. With four or six, they’re spread across the set.

In practice, more than 95% of customers in the Netherlands and Belgium repair all their chairs at once. That’s not a coincidence. If one seat has let go, the others have been living with the same stress for the same number of years. Sometimes they follow without warning. Doing them all now saves you up to €135 in shipping on six chairs — and saves you from ordering twice.

No. The kit ships in a Letter-box friendly postal box and comes with your regular post. (FEFCO 0427 cardboard box)

Yes, if you provide an email address with your order. You’ll receive an automatic notification as soon as the shipment is created.

Within Europe, usually a few days. For destinations further afield — Australia, for example — allow up to 13 days.

Estimated delivery times by region:

• Europe: 2–7 business days (Benelux often next or second business day)
• North America: 5–9 business days
• Asia: 6–12 business days
• Oceania: 7–14 business days
• Africa & South America: 8–14+ business days

Yes. The 14 days is a conservative guideline — the adhesive stays effective beyond that point. We’ve factored in shipping times, including longer routes to Australia and New Zealand. Once your kit arrives, you have plenty of time to plan the repair without rushing.

“In practice, the adhesive remains fully effective for several weeks — the 14-day guideline is intentionally conservative.”

Unused wooden discs, syringes, and scraper can be returned within 14 days. Return shipping is at the buyer’s expense. Contact me through the website to arrange a return.

Fritz Hansen’s ReNew programme is aimed at large commercial clients. Private owners are typically referred to their dealer, where a full seat replacement runs around €350. This kit does the same job for roughly 12% of that — and you keep the original shell, with its patina and its history.

The few repair options Fritz Hansen does offer for individual chairs involve replacing the same plastic mounting plate that failed in the first place. It’s a temporary fix, not a solution.

The adhesive is highly reactive and contains almost no stabilisers – that’s precisely what gives it its bonding strength. Plan the repair as soon as the kit arrives. Don’t set it aside for later.

10-year guarantee on the bond
If the seat comes away from the wooden disc within ten years, I’ll send you a replacement kit at no charge. All I need: a photo of the underside of the chair, your name and address, and the order number from your original purchase. Return shipping for the replacement kit is at the recipient’s expense.

More than a thousand chairs have been repaired with this system. None have come back. Not luck – the wooden disc and this adhesive together are stronger than the original factory joint.

The guarantee covers the bond between the wooden disc and the seat shell under normal domestic use. If the shell itself breaks through impact or overloading, or the veneer separates internally through age – that’s a different failure, and I’d be misleading you to promise coverage for that too.

Yes. I regularly work with hotels, restaurants, universities and public institutions — dozens to hundreds of chairs at a time. Depending on the number and location, a combination of DIY kits and an on-site repair service is often the most efficient approach.

Get in touch and tell me how many chairs you’re dealing with. I’ll work out the best solution with you.
