ROHO® Hybrid Elite SR™ seat
Checking pressure
A daily check by hand is recommended to ensure the cushion is
properly inflated.
The cushion is most effective when 1/2" – 1" of air is maintained
between the cushion insert and the user's lowest bony prominence.
1. Slide your hand between the cushion and the user's buttocks.
2. Lift the user's legs slightly and feel for the lowest bony
prominence.
3. Lower the user's leg to a sitting position.
4. At the right air pressure, you will only just be able to move your
fingers.
