Although it is expensive for my standards, I don't risk getting another one. I had an even more expensive one that peeled as soon as it got wet. While this one, after a child accident and a washing machine dryer, is intact like new. Now I am ordering it again for another bed.

Very high quality material. We use the same for the double bed. Materials that do not break from repeated washings and do not cause allergies. Its elastic does not break after years of use.
