The Spheres is the latest addition to Amazon’s downtown Seattle headquarters, and offers employees a work environment shared with over 40,000 plants, bringing them closer to nature as they work.

To explain this groundbreaking new building, Amazon established a free, public visitor center at The Spheres, called Understory. The name refers to the lush habitat between the rainforest floor and canopy and provides a fully immersive, 360-degree experience where visitors can get up close and personal with the science, engineering and plants behind The Spheres.
