We have, incidentally, bought as a replacement mattress for the BabyBjörn 041,121 Cradle Harmony after the original mattress got mildew stains in the basement. It is a bit wider, so I wanted to cut only. Since the material of the side walls of the bed gives way a bit, but that was not necessary. I find the Träumeland mattress better than the Baby Bjorn mattress.
Now I'm going to buy the playpen mattress Träumeland. Because I thought it was only fair to amend my urspüngliche rating (three stars).
Original Review:
I have the mattress, among other reasons ordered because it is mentioned in some review that it does not smell.
I can not confirm, unfortunately.
Because it makes otherwise a good impression (very thoughtful, I find, among other things, that the zipper on the back is in the middle of the mattress, so you can remove the reference well and draw up again), I would probably keep, though the foam would washable. Unwashed I had always the uncomfortable feeling that the chemical that smells so strict, merges with the breath of my baby.
Pity!
