Abstract
An ergonomic chair having a shell that defines a seat and a back. The shell includes a lower back support that extends upwardly from the rear of its seat to about the middle of the back of the chair. An upper back support also extends upwardly from the rear of its seat. The upper and lower back supports can be resiliently flexed independently of each other to respond to movement of the user's back against the back. The shell is mounted to a base which enables multiple identical chairs to be telescopically stacked in a space-saving configuration.
