I built this with the help of avery able friend.

This is the best design for a high-chair that I’ve encountered. Instead of being enshrined in a wooden tower (or more likely plastic, these days…) back away from the table, the Trip Trapp brings the child to the table to share in the meal. It’s also a lot less to clean!

Designed by Peter Opsvik in 1972: http://opsvik.no/index.asp

We had an original Tripp Trapp for our first child, and when the second arrived I decided to try to build one as my first real woodworking project. Not the best choice for a first project! All of the angles made it quite a challenge. It was especially hard to get SketchUp to deal with the half-round angled slots. I managed to do it, but I remember that Sketchup fought me the entire way. I even asked for help on several SkeketchUp forums and no one was able to figure it out.

What you see in the photos was meant as a prototype and is made out of re-cycled pine house framing. My plan was to make another from Rimu, but other projects beckon….

If you’d like to try to make one yourself, here is a link to the SketchUp model as far as I was able to take it:

One of the photos below shows the jig we built to make the curved back rest parts. These were two thin 5mm stripps of plywood (ran through thicknesser) glued, and pressed into the jig.

I’ve also included a template I created from measuring off the real Trip Trapp of the holes at the top of the posts.

In the model you’ll see I wanted a mortice and tenon for the foot connection, but that was a bit too ambitious. Next time!

Also: Tripp Trapps also have a bent band of wood to allow it to be used with children that can’t sit up yet. I router the holes for this but did not make one yet. Probably will require steam!

Kewl! Wish I had seen this a few years back. Won’t need another one for a while – like until I have grandchildren. But perhaps someone else I know may need one. Hmmm….

You should consider rounding off the corners of the seat and foot rest that stick out. I’m working on one now and set it up for my daughter to try out and see how she likes it. Getting off she went down the wide and scratched her back on the corner. I’ll be making the seat back jig shortly to finish mine up. Could have used your diagram earlier, I based mine off a pic from amazon and went with a 60* angle which seems like it will work fine; your 73 off the original might be more refined.

This really makes sense!

My daughter has two kids, the high chairs did last long enough, mostly plastic, and they were way too expensive!

I would like the Sketch up file too! When I click on the link above I get a blank sheet!!

our first was in since she could sit up… she still sits in it at every meal, doing homework at the table… she’s seven now… very efficient use of some wood!

It’s been a while since you guys started this thread etc. but I could really use that template too. Would you be able to send me that file? Or even post the numbers?

Well, almost a year gone by. I finished the chair last winter but got busy with the farm. I thought you might be interested to see the finished chair. It should be in my “projects”. Thanks for your help!

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!

Have your say...
