It's a super cute baby sofa! It has a hole in the seat, so it's also great for bath time when you're the only one with the baby! It has a simple design that blends in with your living room, and can be used for outdoor activities like at the pool or beach, picnics in the park, or even at home. It can be used for practicing sitting up or as an alternative to a Bumbo seat. It's also perfect for half-birthday photos and anniversary photos! (^-^) You don't need an air pump because the air goes in when you move the pillars up and down! Even if you deflate it to move it, it only takes about 2 minutes to inflate it again! I think it will be very useful as it can be used in various situations! *\(^o^)/* Richell Fluffy Baby Chair Korean Kids Goods Baby Chair Bath Chair Baby Swimsuit Bath Chair Bumbo Sitting Practice One-Person Bath Baby Bath Chair Half Birthday Birthday Photo
