Harbour Dining Side Chair is an extension of the Harbour Chair family and has a new seat that easily fits into compact spaces and under tables, but still maintains the same comfort that the original Harbour chair was designed for.

The Harbour Dining Side Chair is also available in a split seat version. The chair is part of Audo Copenhagen's Harbour series, which includes a range of seating with a focus on minimalist comfort.
