Spex Seating · Rigid backrests · AC-047
The Spex Vigour Back Support is a full-height rigid wheelchair backrest from Spex Seating in New Zealand. Spacer fabric over a ventilated shell lets air move behind the trunk. Backrest angle and seat depth can be changed with the user sitting in the chair. Four brackets hold it to the frame, and a positioning kit of lateral stability wedges and a sacral block is supplied with it.
For users who need substantial trunk support yet stay active in their chair. Heavy-duty brackets raise the weight rating for larger users. Set-up of the wedges and sacral block is a job for a seating clinician.
