The Varilite Evolution Back is the back system of choice for wheelchair users with moderate to maximum support needs. Therapists recommend the Evolution Back because it is easy to mount and can be removed 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. It handles third-party secondary supports with ease and works with the Varilite PAL to provide an elegant, low-profile, integrated back and swing-away lateral support system.
To allow for client growth, aluminum brackets permit 1" of lateral adjustment. Steel pin bars slide anteriorly and posteriorly to allow for back angle and seat depth adjustment. Pin bars simply slide in the receiving cane clip and snap the system into place. The Shell's back panel is flat for flush mounting of headrest hardware. Contoured sides provide lateral support and attachment area for hip belts, laterals and hip guides. A two-way valve allows air in and out of the cushion for a custom fit. Cushion foam is thickest along the vertebral column for added comfort and protection.
The Cover provides maximum padding and protection. Four-way-stretch mesh top fabric wicks moisture away from the body. A large loop panel on the backside of the cover securely attaches to hook strips on the shell, while a wrap around handle flap prevents downward slippage for even the most active user. Reticulated foam inside the cover promotes air exchange and improves pressure distribution. Evolution Back cover meets ISO 7176-16 ignition resistance standards for upholstered wheelchair components.
