Sella homo sapiens is a chair composed of stylized flat geometry. Combination of flat images appears volumetric as a chair when seen from an angle. Its image is different from every angle. Covered with soft, tactile, approachable, warm material of industrial felt sheets, this very flat chair is very comfortable to sit on. Each flat components of this chair can be separated and stacked to fit in a smaller box for economical shipping, to be assembled by a user. Slightly distorted from a symmetrical composition, its image might resemble anything from cartoon icons to plastic bubbles to mid 20th century classic chairs, but its most significant influence comes from one of the earliest work of art made by mankind----geometry of human being, drawn in cave. Thus this chair was named in Latin, “chair for human”.
