Purchased this item a few months ago for my toddler’s bed. Thank goodness my toddler doesn’t normally wet herself because to my surprise, this cover is NOT waterproof!!! My toddler had an accident in her bed for the first time and it completely soaked through. Read the description for this cover just now and noticed it states water RESISTANT!!!! Huge discrepancy in the name and description of this product. I wouldn’t even call it water resistant since it completely soaked through!!! Have a rag by the bedside in case there’s an accident of any kind. I definitely would not recommend this product if you’re looking to protect your mattress from accidents in the middle of the night!!! Wish I knew this before purchasing this item. Gave it 1 star as I had to but would give it 0. 

Update 3 days later: They have now changed the name of this product on this site from Waterproof Mattress Cover to Hypoallergenic mattress cover a few days after I posted this review. Good because it was misleading!
