I Started this project last winter, finishing just in time for our little girl who arrived on Christmas eve. I had seen this chair in a baby store and it “looked” like it would be easy for me to make. Also, I liked the idea of the little one bellying right up to the table with the rest of us.

I bought the plastic chair rest piece, and in one way it came in handy to take measurements from. On the other, it made it more difficult as I had to make the chair to match it. Doubly difficult was that it seems the dimensions for the older chair is not exactly the same as the chairs they now produce and new plastic seat back, front guard etc.

Kokako was nice enough to send me some plans but they didn’t seem to match the plastic back i had to deal with. i made my mold/ jig the same way and it turned out perfectly.

Unlike the Tripp Trapp, I have my seat back hardware hidden from below instead of routed in the back. Also, I had seen complaints and video of the chair tipping back so I lengthened the bottom rails. The chair is on hardwood with felt pads underneath as well.

I mortis and tenoned the joints using the miter guage on the table saw set to the proper angle (cant recall off hand) for the male pieces and used my protractor to set the angle of the table of my drill press to rough out the female pieces. Finishing them square by hand.

Once all the head scratching was done i was able to hide my mistakes and have a nice sturdy chair for many years to come. It has seen a great deal of use in this first year. In fact, the footrest is completely burnished from those little feet sliding around!

I’m sure I’m missing some of my process. Please feel free to contact me with any questions. Someone was nice enough to take the time to help me and I would be happy to do the same.

I have added a drawing i have made myself in the event that I want to make another chair.Some people have asked for various dimensions and I’m sure it would be useful for everyone to see a drawing. I would have begged, borrowed or stolen to have had my hands on a drawing before I started! It is a high quality file, it looks like the upload process may have downgraded the quality. I have broken the photo into 2 halves, hopefully that allows everyone to see the dimensions.

Very nice work. Almost too nice, for something that will get all kinds of food and baby bodily substances on it.

Thanks for that. Actually, it’s standing up quite well. I forgot to mention I used walnut oil to finish it. Nice piece of mind knowing you can finish wood with it or put it on a salad!

Awesome job. Special thanks for sharing.
Now I know after the cradle I have to make one of these. :-)

Welcome to LJ. Congratulations both for an elegant build and for your precious Xmas gift that’s already 1 year old. She must be about ready to use it by now. Best wishes.

Thanks so much for the posts everyone. Its nice to be part of this community. She certainly has been using the chair a lot. In fact, I’ve already had to move the footrest down two notches!

Hi there,

Any chance you could send me the drawings for this chair?
I would really like to build this one for my new son!

Greetings from a Dutch guy in Argentina!

Does anyone have measurements for the back rest curves? Any numbers for the chair at all would be great. Thanks.

I’ll have a look for you when I get home this evening. If I can find it I have some plans drawn out that I may be able to add to my project photos.

Ok, I’ve added a photo of my drawing to the project photos. It looks as though the upload process may have downgraded the quality of the file. If you have trouble reading some of the dimensions private message me your email and I will send you the original. Best of luck!

As far as the back rest goes, I don’t know/ feel like figuring out the radius size. However, I measured the depth of the curve. So, I put a straight edge across the straight ends of the backrest and measured from there to the centre/ furthest point on the curve = 1.4375” (this works for me though may not be exact to Tripp Trapp standards as my bending process was far from exact). Also, for your reference, there is roughly an inch of “straight” on either end exposed where it fits into the sides of the chair. A picture is worth a thousand words but since I don’t have a picture, I had to use a thousand words! Hopefully, that gets you where you need to go.
