I'm currently working with a seating clinic to get a new manual rigid chair and they are recommending both a wheelchair cushion and backrest made by Ride Designs.

The back rest has been molded to fit my back specifically, as other backrests we tried did not make contact throughout my back. The demo wheelchair cushion felt comfortable but it wasn't my correct size.

Is anyone familiar with or have experience with Ride Designs wheelchair cushions or backrests?
