It is a manual relax chair which was one of the best purchases we made for our baby. Personally, I had been thinking about getting it for a long time due to the excessively high price, but having it in our possession for three months now (he is five months old) I would give it again without a second thought.

In its positives:
It swings very easily (just touch it with your finger and it moves). After the 3-4 month mark, the baby swings it on his own.
It is very lightweight and does not take up space when folded - we take it everywhere with us.
It is safe - no matter how much it swings, its base does not move.
It puts the baby to sleep very easily on it (I would give it five more stars just for this) and then we transfer him to his bed like ninjas.
The breathable fabric was the best for our baby who cannot tolerate heat at all in the summer.
The fabric comes off very easily to be washed and dries quickly.

In its negatives:
Its price. Because with babies we do not know if they will eventually like something, when a product is expensive, we take a risk. However, I have not heard anyone regretting it as a purchase.
One out of ten times, it leaks from the diaper in the middle. But sh*t happens.

Our friends lent it to us and I would say that it is one of the best on the market. Very lightweight, ideal for supporting the baby, washable, however, it depends on the baby if it will suit them. The first child enjoyed it, while the second wanted to be held after a while. I think the price is a bit high, if you have the opportunity, buy it!
