7.10.2 Seat cushion

Wheelchair seat cushions are used for pressure redistribution while sitting. Depending on the version, the seat
cushion contains a resilient foam base and possibly additional gel or air-filled inserts. The foam base is anatomic­
ally shaped in some cases.
The covers and breathable materials reduce shear forces and ensure a high level of seating comfort for the user.
The seat cushion can be removed for cleaning. Following cleaning, the seat cushion is secured to the seat by a
hook-and-loop fastener to prevent sliding.
Detailed information regarding use, cleaning and maintenance can be found in the enclosed instructions for use for
the seat cushion.
