This is a highchair I just finished for my daughter. It is a blatant copy of a chair named the tripptrapp by a company named Stokkee. A good design is a good design and I am not about to pay $300 for a highchair that I have to screw together made of 5/8” plywood. Here are the features of this design that I thought were truely ingenious and merited a copy, only built to higher standards. First the chair is adjustable to grow with your child, this is accomplished via parallel dadoes cut in the side pieces. Second the table the child uses is your own, the chair slides up and under the family dining table so they are included in mealtime. Lastly, due to having a bottom platform that is also adjustable, there is always a “floor” for your child to place their feet.
My chair is made of jatoba with prefinished 3/4” maple plywood as the two platforms. The safety rail across the front is made from a bent lamination of ash and is screwed in. This way I can remove it later. The bottom joint is an angled bridle joint pinned with ash dowels, definately not a feature of the original. The eyebolts in the top platform are for a harness that is made for the actual tripptrapp, gotta love ebay.
