This baby chair has a built-in pump for easy inflation and a function to prevent tipping over. - Target age: 4 months and up - Model name: Croomy Sitting Practice Chair ORC-N(P) - Features: Built-in pump for easy inflation - Safety features: Anti-tipping function - Usage time: Usable in 2-3 minutes I used this chair a few times for a month, but my baby kept escaping, so I'm selling it. The chair itself is the only item; there is no box or instruction manual. I will deflate it for shipping. Thank you for looking.
