But what did not work - and it surprises me that here no one has criticized - is the handling of the cover. The confined itself to one of the short sides of a zipper. As soon as you take them from that was plenty of difficult and I was afraid, when relating it would be problematic. Not even close! It was hell! After squeezing, pulling and stuff about an hour he was on the back and I sweat soaking wet. It was like trying to in a moist Jeans 3 sizes too small to squeeze. I do not know how the others have done here, who the mattress rated as positive. Maybe there's a secret trick, I do not know. He can not really be broken in me, as in the washing instructions 60 ° is, but I have washed him even only at 40 ° and have to air dry to dry. Anyway, it was an experience that I do not want to repeat as soon - and certainly not on a regular basis! Moreover, I doubt that the reference would join the more than 3 times. I now raise a precaution to respect my old mattress on (by the way, on 3 sides has zippers so they just fooled and then "zipped" must) and order an additional mattress, so I do not have quite as often wash the thing.
Because the main thing is yes on a mattress inside and not the reference, there's still 3 stars ...
