Crib bumpers

Jessica
Hello! So I obviously know that we're not supposed to use/have crib bumpers because of the risk of suffocation. But almost every picture of nurseries I see the crib has bumpers. (It makes the crib look so nice and more put together! Haha) 
So I'm wondering- do people just put them on for looks before the baby comes or while they're sleeping in the bassinet? I got the bumpers to match our crib bedding and wondering if there's even a point in having them. Can we use them down the road when baby is older? What's the point of them?? Thanks!
