This stool, named "Triângulo", was designed and produced in 2019 by Miguel Saboya, a brazilian designer living in Portugal. It is a height adjustable stool made in metal and kambala, a wood species from central and eastern Africa with strong mythological references in both Africa and Brazil.  The "Triângulo" stool is inspired by simple geometric shapes - two equilateral triangles that are joined by bars atop of which the circular seat is screwed.
