We have this super nice BabyBjörn bouncer which our son does not use anymore. We used it from shen she was roughly 1 month with some blanket under her back and butt to better support her. But then she liked it so much and it's definitely great to free parents' hands. It can be used until when the baby is 9kg.
It's super robust, we used it only for few months and it looks as new.
TWINT or cash.
