Intended Use and Descriptions
Otto Bock’s family of wheelchair back cushions are used to improve the seated posture of
the user, as well as to provide pressure relief, by properly supporting the trunk region and
distributing existing pressure over the largest possible area.
Application
Improved thoracic lateral support if the user’s sitting posture requires additional support.
Support for an orthopedic deformity such as a lordosis, can be inserted in a compartment
between the solid base and the pad.
Using the integrated FLOAM® pads for Back 2, Back 3 and Back 4 in the vertebral region
can reduce risk of decubitus ulcers.
The Otto Bock warranty applies only when the product is used according to the specified
conditions and for the intended purposes, following all manufacturers’ recommendations
(see 2-Year Limited Warranty section for more details).
