Repairing a Cane Chair Seat

You might be surprised how easy it is to repair the cane chair seat of your bentwood with just some ordinary household tools.We have a whole set of Thonet bentwood chairs that my parents bought in 1978 and 1981 (how do I know? the year is stamped on the chair underneath the seat).

These classic cane chairs are perfect in our kitchen. With all this use, we’ve had to periodically repair a seat here and there, even though we have been putting chair cushions on them.

First, I would take those Thonet chairs to repair shops. But now that I have repaired a few cane chairs myself, I just want to share with you how easy it actually is.


You will not need any special tools or skills for this repair. Hopefully, this tutorial inspires you and gives you the confidence to try to tackle more DIY repair projects in your own home!

What you need

Obviously, you need the cane chair replacement. It is very easy to find online. When you do order it, make sure it actually matches the hole sizes of your existing cane chairs.

Then you need ordinary household repair tools:



hammer


flathead screwdriver or small chisel


boxcutter


scissors


wood glue


and pliers (just in case)

Cutting out the old seat

I like to cut out the old cane seat to give myself a bit more room to maneuver around. You can cut closer to the edge as I did!

Cutting along the spline to loosen the glue

With the box cutter, carefully cut both sides of the spline to loosen the glue. Be very careful with sharp knives!!! Also, try to not cut into the actual chair the best you can!

Chisel out the old spline

With your flat-head screwdriver or small chisel, take out the old spline. This is the most tedious and effortful part of this whole project. Depending on how much glue was used before, it could take a bit.


Try to work mostly from the center of the chair. If you work from the outer edge, you might damage the chair a bit (I’ll show you down below what that looks like). Those little nicks wouldn’t be the end of the world even though you want to avoid them as much as you can.

Soaking the cane seat replacement

Now would be a good time to soak the replacement seat in lukewarm water for about 20 – 30 minutes. I always like to set myself a timer so I don’t forget!

Cleaning out the groove

With your chisel or screwdriver also clean out the groove as best you can. It might not be perfect but in my humble opinion, it doesn’t have to be!

Aligning the new cane seat

Take your soaked replacement seat out of the water and shake it off to get rid of excess water.


Place it on top of your chair. It should be bigger than the seat. Now, cut it to size with about ½ to 1 inch of overhang on all four sides (or all around in case of a round seat).

Find the wooden wedges that should have come with your replacement seat. Align the cane and press it into the groove with one of the wedges. Take your time now to align the seat front to back and left to right. It is much easier to do this now than later!

Find the next wooden wedge and press the cane into the front groove with it. Check it for straight alignment one more time. Then use two more wedges to press the seat into the sides of the chair.

Removing strands

With the four wedges holding the cane in place, carefully remove any unneeded strands on the outside. This helps with putting in the spline.

Pressing the cane into the groove

Your set should come with 5 wedges. Using the 5th wedge, press the cane into the groove with the hammer. Doing this, I often lose the other wedges. If that happens, simply press them back in.

Cutting off excess cane

With your scissors cut the excess cane. This step is a bit optional but helpful in my mind.

Adding the wood glue

Now, put the wood glue into the groove. Note: I have decided that it’s easier to only apply wood glue to the straight sides of my chair and not in the rounded corners. While it will still be stable enough, it will make cutting out the spline easier in the event that I’ll have to repair this chair some time in the future.


Also, try to get the glue right into the groove and not onto the cane.

Attaching the new spline

Starting at the center in the back, press the new spline into the groove (with the narrower side down). Then press it in following the groove. You can use your hammer to press it in.

When you come all the way around, cut the spline. I recommend cutting it a tad long and if necessary cut it shorter than cutting it too short the first time around.

Cleaning up excess cane

With the box cutter or the chisel, carefully cut away any excess cane that is sticking out.

Letting the repaired cane chair dry

Now, let the repaired cane chair dry for 24 hours and do not sit on it yet! You may have noticed that the cane might have been wavy before but how it should be taut and straight.

In the above picture, you can see that my repaired cane chair has a few nicks. Some of them came, believe it or not, from the previous professional repair job. And some were my own. I will just take some black lacquer and touch up those spots.


And that, my friends, is it! I don’t find the process complicated at all. I hope that you will be proud of your work and that you will enjoy your chair for years to come!

    what should it cost to repair a Cane chair? I paid a man almost $500 to repair an antique chair very much like yours. What should it have cost?

      Hi Patricia, it's hard to say how much a professional chair repair like this should cost (not knowing the labor rate in your area). The replacement kit is about $40. It takes a few hours to do it. In any case, it will be A LOT cheaper to do it yourself. Hope this helps 💛 ~ Anja

    Super good video. Great explanations. I have 6 chairs that could use repair. Some need a lot more than others. So thank you very much.

    You did a great job of explaining the process. This was very helpful I also have 6 chairs I have refinished and all need re seating. Thank you so much I didn't realize that it was something I could actually do myself.
