Baby seat for help sitting up independently

This is like a pillow that has openings for your legs to come out and it supports the baby and helps them get the muscles that they need to be able to sit up independently!! I would say this is 3 to 9 months.. until the baby can set up on their own!! I love this. I use this. It was really nice for support.!! you can put the baby in and the baby stays. It doesn’t flip over so it’s really nice. I purchased this through Amazon. The cover can come off and be washed and it can be wiped down. It’s like a pillow with cotton inside very nice condition no marks no stains.
