Air cushions need continuous monitoring. They must be pumped and checked and without proper inflation the user risks bottoming out. If over inflated, the pressure relief is jeopardized.

Gel cushions require daily inspection and kneading to assure the gel has not (migrated) moved, increasing the risk of bottoming out. Both gel and air cushions when damaged often require dealer intervention and repair leaving the client dependant on a back up plan while repairs are made.
