I noticed immediately that the pad was thinner than all that I have been / had. Did everything as proposed, first washed at 60 ° C and then into the dryer. Then immediately carefully reared (mattress size 100 x 200) and determined that the pads are a bit too big. I then rumgezogen with the fitted sheet. Unfortunately, the pad is moved every morning and wavy. You have to make the beds every morning new. That I had with any other edition. Too bad!
