The Evolution Back Deep has the added benefit of deeper contouring and extra lateral support. Available in tall sizes and a variety of widths, it is the ideal back system for the geriatric user, or anyone with fair to poor trunk control. Therapists recommend the Evolution Back Deep because it is easy to mount and remove with one hand, even for the user without fine motor skills. The system is lightweight to conserve energy expenditure for the client who manually propels. Mounting hardware, which comes pre-installed, provides a wide range of lateral, seat-to-angle, and seat-depth adjustment.
