Chair Size

Chair Size:

Chair size is measured centre-of-arm to centre-of-arm. Typically, chairs are provided in widths of 19" to 22", with some stadium chairs available in 18" widths and some premium models available in widths up to 26". Chair size impacts both patron comfort and capacity, understanding this relationship is critical to meeting client/owner expectations.
