“outstanding”
When I bought this , my baby was barely around 4 months old, she didnt know how to jump in it yet. She was mostly sliding from one side to another. Soon enough she learned had to jump, and hasnt stopped since. It became her favourite entertainment, and when I couldnt get her to sleep, I would let her jump in it, and minutes after she'd jump herself to sleep.
It has great sound effects, plenty of toys to explore, music, lights , pretty much everything that could hold an infant's attention. I also loved the little head rest.
