I found 3 High Chair Plans for this page. Create a comfortable, sturdy High Chair for your child. There are designs with and without the tray and I have included a couple of Doll High
Chair Plans for fun.
The most detailed plan, without a tray, comes from Ana-White.com. Ana shows you how to build a restaurant high chair using pine boards, pocket hole screws and wood glue. Ana has great diagrams, materials lists, a cutting list and good written instructions. See the Ana-White.com High Chair Plan below.
The best plan, with at tray, comes from MotherEarthNews.com. This Wood High Chair has a removable tray and is quite sturdy and stable. The author also suggests measuring your dining table height to make sure the arms ( without the tray ) will fit under the table. See the first plan below.
