Is your child to old for a high chair, but too short for a standard chair?  

For the cost of a cheapo plastic booster seat, you can build your child a modern higher chair.  This simple sturdy plan is easy to build, features a foot rest and is easy for youngsters to climb up on.  This chair is not meant to replace a high chair, and does not offer the security and safety of a high chair.

My only coworker has been complaining quite a bit about her office chair, so I thought it was time to show some appreciation for my number one associate and build her a higher chair.  She of course, had to help.

Mom, how and I supposed to work if you keep making me take pictures?
This chair is perfect for preschoolers, who don't need the security of a high chair, but still could use an extra boost.  For sure a luxury if you had to buy such a chair, but in our DIY world where all things are possible on the smallest of budgets, why buy a plastic booster seat when you can make a mod style solid wood chair for the same cost?  And this chair is really cool because the base supports act as a step up, so children can seat themselves at the table.

This chair is child sized, for an adult sized table. Could be modified to a bar stool with modifications to height and depth

General Instructions

Please read through the entire plan and all comments before beginning this project. It is also advisable to review the Getting Started Section. Take all necessary precautions to build safely and smartly. Work on a clean level surface, free of imperfections or debris. Always use straight boards. Check for square after each step. Always predrill holes before attaching with screws. Use glue with finish nails for a stronger hold. Wipe excess glue off bare wood for stained projects, as dried glue will not take stain. Be safe, have fun, and ask for help if you need it. Good luck!


Step 1

Begin by building two of the above pieces. Make sure both match exactly. Use with either 2 1/2" screws countersunk and glue or 2 1/2" pocket hole screws.

Step 2

Join the two sides with the front apron/support as shown above. Use the same screws and glue.

Step 3

Now the top. This time you will need to use 2" screws so the screws don't poke through the seat. Also screw the side aprons to the seat.

Step 4

Now build the back. Go back to the 2 1/2" fasteners. Adjust for square.

Step 5

Attach back rest to the back support pieces.

Step 6

Finally, adjust the seat rest to fit in the seat back. Measure, use a level at the top, and screw in place. I actually sat my daughter in the chair to get the support just right.

Finishing Instructions
Preparation Instructions
Fill all holes with wood filler and let dry. Apply additional coats of wood filler as needed. When wood filler is completely dry, sand the project in the direction of the wood grain with 120 grit sandpaper. Vacuum sanded project to remove sanding residue. Remove all sanding residue on work surfaces as well. Wipe project clean with damp cloth.

It is always recommended to apply a test coat on a hidden area or scrap piece to ensure color evenness and adhesion. Use primer or wood conditioner as needed.

Nice chair. Thanks for sharing.

By the way, can you share the materials and specs of the table. I think it is very nice to make both.

Thanks so much.

This is my second chair. But my first since I got my kreg jig, i am having difficulty with the pocket holes. The drill and bit are to long to fit between the legs and supports. Any tips or ideas?

built this is two (very hot TX) days. we used 1x6 for the seat, cut two, leaving a gap for small fingers to grip as they climb up. Grandson (2.5 year old) mastered the climb the second time. All grown up tested it and love the design and sturdiness of it.
