For the rest, apart from the "vibrations" that baby will not really appreciate it also remains in the classics, more "strength" of swinging, while music. The nacelle is therefore hammock type no rigid folder that would force the fragile back of baby: perfect for the target age. The fabric is nice, unisex and enters the machine (essential).
The play arch comes with plush but we can also bring its own toys, perfect when baby begins to have favorites :)
It is certainly an investment (130 at the time of this review) but if you plan to have more children or if you are a professional, it's really an interesting purchase.
