Intellect Wave cantilever chairs are available with an add-on or removable rocker accessory that supports learners who benefit from motion. The rocker can be added to all sizes of Wave cantilever chairs (13 inches, 15 inches, 18 inches) to support all ages K-2 through adult. It can be applied to any Intellect Wave cantilever chair, whether the chair has been in use for the past 15 years or is freshly specified for a new facility.
