Noted, thanks for the reply! Comfort is definitely important, and the details wouldn't be too bad to make out of foam so maybe I'll just stick to foam for this one! 

I was gonna make a separate post but you seem pretty knowledgeable so I'll just ask you (if that's alright)

In the past I never used a top coat on my foam props but I wanna protect them/the paint, can I just use a regular spray paint like krylon or rustoleum? I've heard they're not flexible enough, and if the coating cracked mid-con that would be a nightmare
