The Varilite Evolution Back is the back system of choice for wheelchair users with moderate to maximum support needs. The Evolution Back Deep has the added benefit of deeper contouring and extra lateral support. 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.
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.
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.
Evolution Back Deep systems include a PSIS block and Supplemental Lateral Pads. These accessory pieces are made from closed-cell foam that will not absorb water and is resistant to bacteria. The PSIS (posterior superior iliac spine) block provides support to the sacrum at the PSIS level, promoting an anterior pelvic tilt and spinal extension. The Supplemental Lateral Pads help users who lean to one side maintain an upright position, and are especially beneficial for geriatric clients.
