What "waterproof" should mean on a label
A true waterproof layer is a membrane — polyurethane or TPU — laminated behind the fabric. It blocks liquid completely, and it also blocks vapour, which is why cheap waterproof covers feel hot and crinkle.
A water-resistant fabric sheds spills for a few minutes and then lets them through. That is often enough for a drink, and never enough for a toddler.
The trade-off nobody mentions
Waterproof and breathable pull against each other. A membrane that stops liquid also stops moisture leaving the mattress, and a mattress that cannot dry is where smell and mould start. For a child's bed, a washable quilted pad on top of a breathable cover is often the more practical combination than one sealed membrane.
What to check before buying for a child
Zip security — a child should not be able to open it. No loose cord or loop near the head end. And a fit tight enough that the fabric cannot be pulled up over the face.
For pets, the priorities change
Claws, not liquid. Look at the weave and the seam construction rather than the membrane; a punctured membrane is no longer waterproof, and a torn seam is no longer a barrier.
FAQ
Is an encasement the same as a mattress protector?
No. A protector sits on top and comes off easily. An encasement zips around the whole mattress, so it also covers the sides and the base.
