The main reason was that the carriers run at the front carrying relatively far down (waist height). The other baby carriers, the carrier went through under the arms, which is super uncomfortable with a larger bust.
In addition, the fabric is nice and soft and the carrying aid is ruckzuck apportioned and very safe.
Contrary to the description I do not think that the Bondolino can be used continuously. For this purpose, m. E. the ridge down to wide. We have therefore dispensed with the 3rd and 4th month on the Bondolino because the spread lt. Doctor would have been too large (very delicate child).
Meanwhile I use the Bondolino much more often than the sling because it's so beautiful fast. Back friendly I think as baby carrier, however, the sling because the child is even better, "docked" to the wearer's body.
The backpack is very convenient if you use the supplied cord to fix the carrier. Visually, one could solve the beautiful safe.
Our baby (now 7 months) sits at least with enthusiasm in Bondolino and kicks before joy when it sees the Bondolino even from afar.
And when it is sleeping or cool breezes blowing, you can use the headrest very good. The Velcro dots are very practical, but also very loud to solve for a sleeping child. But that was similar in all tested wearing. I would again buy the Bondolino.
