Since the sheets and the sheets are washed with us depending on usage once a week in the cleaning and this still looks great, which speaks for the good quality of the product respectively for good cleaning :)
What described the size as in the previous review should not agree I do not understand - possibly the mattress used was too high? Our old Spanish mattresses were all out of the norm and above-normal high so wanted to fit the none of the sampled by us fitted sheets properly (and we have tried many different sheets!). The sheets were all press or limp when choosing a larger format. Both were for appearance and durability of the sheets harmful (fast fraying and ugly wrinkles to a some sleep). After we have replaced all the mattresses last year disappeared the problem (our current mattress have a height of 20cm).
The quality of the fitted sheet is reflected in the price more than adequate and definitely recommended!
