Frequently Asked Questions
My cribﾠmattress sits on top of a wood board. The air holes on the bottom of the cover are completely covered - does that matter at all?
Place two long, thin pieces of wood (approx. as thin as a pencil) under the mattress (on top of the crib base) along the sides. ﾠThis will elevate it and give enough space for the mattress to breathﾠand will have no effect on the baby's sleeping pattern.
What is the crib mattress cover made of?
6mil low density, food grade polyethylene
Should I put a waterproof cover over the Harlow's Earth Crib Mattress Cover?
