A really good mattress. Beautifully (12 cm high), so they do not is now worn out, but not too hard. Sure there are much cheaper mattresses, but to use the Mattress in the junior bed so for some time. And to think that the little ones yes the first few years to spend just in the first time / much time sleeping, you should not skimp on a good mattress. Have also had a publican mattress for the crib. Is also great, as almost all products from Julius Zöllner. One am completely satisfied.
