ERGO Info

The body was designed to move. If your chair has a recline tension control, adjust it so the backrest supports you in both upright and reclined positions.

Awards

Designed to complement the features and styling of the Liberty Task chair, the Liberty Side chair offers beauty, performance and unprecedented comfort in its class. Its backrest features Liberty’s exclusive Form-Sensing Mesh Technology for perfect fit and customized support. The backrest pivots for additional comfort, and the seat has a frameless front edge that is supportive yet soft.
