The Clevamama 7215 is like a fitted sheet is pulled completely wrinkle-free over the mattress. The smooth underside protects the mattress from moisture reliably, the fluffy surface facing upward and so soft that I could sleep on my child without hesitation.

The color of Clevamama does not matter (that's why he is white and without potentially allergenic dyes), because you can not see him yes.
