Here are the plans to build a solid wood stool in any size you want, to suit the use you will make of it:
a seat, a plant holder, an end table, child-size stool...
The top is made from a repurposed piece of wood and the legs are cut out of untreated wood from a construction site.
You can improve the look of the stool by cutting the triangles or arches in the legs, for example.
For info, the size of the stool pictured is: 19 cm (7½ in) high; 25 cm (10 in) wide; 25 cm deep.
To adapt to your own needs and purposes.
