It keeps the baby satisfied for a while. cannot stay there for a long time. I guess it’s not very comfortable. It may cause some damage to the door frame. But generally, it is a good activity makes the baby happy and strengthens his legs. When the baby was Younger, he couldn’t reach the floor so we placed some pillows underneath his feet to help him jump. Age when using approximately 6 to 7 months old.

We didn't use it much because it is extremely difficult to put the child inside. It requires 2 people and a lot of effort, which makes the child lose patience and not enjoy it in the end.

I have bought 2 for my twins and they love it. It gives you the opportunity to do some work around the house while they play. They exercise at the same time and already at 8 months they can stand and move almost completely without holding onto the edges. If they get bored or tired, you can simply lift it slightly off the floor and turn it into a swing by gently pushing. I definitely recommend it.
