Bought for a Matraztze the size 90x200 cm the mattress cover. It was washed by me with 60 ° C (allowed were even 90 ° C) and then placed in the dryer (was allowed) before using. The slipcover is so strongly run that I could relate the mattress so only with great difficulty and the help of my partner. Did not expect at this price a better fit. Otherwise, the quality is good and the Molto layer very fluffy and pleasant, the film also does not rustle.
