Is it really "magic"?

An expensive product for the amount of material!
I am still not completely convinced of all the benefits of Cocoonababy ... A priori, an infant (or at least mine!) Sleeps equally well on a traditional mattress.
In short, is it not a product more {"marketing" / trendy / fashionable /} inflicting guilt that parents actually useful?
And do not forget that, even officially, we will not use more than four months ...
Still, the Cocoonababy is convenient to place the infant around the house or visiting friends: it's very moving bed in the month of office and very easy to move, which is not bad!
As for the cover: no need to purchase a replacement. When one delivered with the Cocoonababy must be washed, they temporarily replaced with a baby bed fitted sheet; it does very well on the interim laundry day!
