For cutting the foil should use a hook blade or just be careful to avoid damaging the Maratze.
After Ausspacken the mattress needs some time to develop to their shape. However, I have given only a good two hours of the mattress and then I go to bed, what has not hurt her.
After a few nights, I can say that I sleep very well with my 90 kilos and 187 cm it. The sleeping comfort is very good for me, because the mattress is not too soft. The mattress has no abnormal height and should fit in each bed with the same dimensions.
All in all a purchase, I absolutely do not regret.
