There is a key feature in the comparison between a crib mattress cover and a crib mattress protector. The mattress protector is 100% waterproof. This means that anything that falls on the mattress will not penetrate it thanks to a protective layer. But we must not forget that this impermeable layer does not allow air to pass between the baby, the mattress protector and the crib mattress. That is why, at Lémur, we do not sell mattress protectors.
At Lémur we prefer crib mattress covers because they are 100% breathable and help protect our baby.
Another feature is that mattress protectors are usually closed and adapted to the mattress with a zipper that prevents the protector from sliding off the mattress or rubbing and staining.
The crib mattress cover, on the other hand, only covers the side where the baby falls asleep, which is what we really want to protect. It is attached to the mattress with elastic bands. At Lémur, we put baby protection before the mattress or crib mattress cover.
