The Vigour HI-Extendable Wheelchair Backrest gives users full height support for maximum trunk and shoulder support just like the Vigour, but features an extra 5cm of height for taller users. The Vigour features ventilated spacer-fabric that increases air flow through the backrest to increase daily comfort. The backrest and seat depth can easily be adjusted with the user in the wheelchair and comes with an additional positioning kit that includes lateral stability wedges and lumbar pads. The Vigour is lightweight but durable, designed to meet the needs of an active wheelchair user who requires a rigid backrest that still leaves the ability to self-propel.
