After trying other brands and types of inflatable cushions that were very uncomfortable, her Occupational Therapist told us about the ROHO cushion. It was easy to inflate and adjust. Loves loves the comfort due to the way it distributes support when she needs to shift her weight. Overall, we are very satisfied with it performance and durability.
I don't know of any weknesses.
