IKEA chair leg extension

My elderly mother really likes the chair, but it is not high enough for her. She has a hard time getting up.

I made additional extensions. 

Print the four main details.

Each of them will require five reinforcing inserts. And one central insert according to the size of the hole in the leg of the chair.

Make inserts from strong plastic, many layers of the wall and with dense filling. They will bear the brunt.

It may be necessary to adjust the details with sandpaper. The gaps are minimal. I hammered in the inserts with a hammer and used epoxy to reinforce.
