Bumbo seats

So I don’t plan to buy a bumbo since I know they aren’t the best for a baby to sit in as it moves their hips. However I’m curious, is there a certain age that would make it ok for a baby’s development? Just curious as I have my baby shower tomorrow and I know family uses them so that may be something I receive.
