Is your child to old for a high chair, too young for a standard chair, and just the right size for a big phonebook that no one keeps around anymore? 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.
2 - 2x2 @ 8 feet long
2 - 2x2 @ 8 1/4" - one end at 10 degrees off square, shortest point
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!
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.
Join the two sides with the front apron/support as shown above. Use the same screws and glue.
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.
Now build the back. Go back to the 2 1/2" fasteners. Adjust for square.
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.
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.
