We opted for the Alvi mattress Hygienica. As such, the mattress is great, not too hard and not too soft, just right for babies. Our son sleeps on such a one. I must say, we have the additional bed of Roba, but this one has a deck area of 80 x 43 and therefore the mattress unfortunately is too narrow.
As such we can recommend this mattress and hope that this was helpful review.
