Sometimes you need to tell the client they have a bad idea!
How does a seat wall make it any safer or absolve you of liability? At 18-22" high they're not taking the place of a guardrail and it's a false sense of security. Never understood that. There's a reason you can't use a bench instead of a railing when designing a deck.
Besides, half the seat walls I've seen are fug and mess up the flow of the space.
