The design comes from a right triangle (each side of the triangle has the same measure), that form pyramids.
The size of de chair, depends on the size of each triangle, will be the size of your cardboard seat. In my project used 24"x24"x24" triangle.
You will need 6 Triangles to get the wholer body of the chair, and you will need 2 triangles to do the seat of the chair.
Step 1: Cut
instruments: scissors, cutter, meter, pencil
Cut 8 right triangles(6 for the whole body and 2 for the top) I recommend you, 24X24X24 inches
Take 6 rectangles and then cut righ in the half and you will get.
6= 12x12x12" right triangles and 6 trapezoids
*In this project you can use recycled or reused old cardboard.
