This bench marks the separation between the clean and dirty sections of the lab. It serves as a reminder to change footwear, a dust-bunny stop, and a place to sit while changing into lab booties. The design had to be removable, yet fit exactly between the two walls of the passage. The top, therefore, has ends that are curved to match the diameter of a circle that would just fit between the walls.
