Only worked for a year
Worked well in the beginning but only a year in a half in, it is already leaking through. Does not get rough use, washed once a month if that.

NOT waterproof! False advertising
This is NOT waterproof, at all. I needed a waterproof mattress cover for my toddler. I bought this. She had an accident, and this cover let everything go straight through to our new mattress. This is false advertising.

Great mattress protector!
We needed a waterproof mattress for “just in case” spills/pets/kids/etc and this has worked out so well. It fits perfectly and does what it says. It’s easily washable and protects the mattress much more than with just a fitted sheet.

[This review was collected as part of a promotion.] its great protection but you do have to change it every few months because stains don't really come off it.

Not waterproof
This mattress cover is not waterproof. Liquids easily leak through. If you have a child that still wets the bed, do NOT get this brand. The product description and title need to be updated to “water resistant” because any substantial amount of liquid will leak through the cover onto the mattress.

Disappointed
I watched the video before purchasing the mattress protector and Target didn't send me the correct item. The mattress protector Target sent me... did NOT have a zipper, as shown in the video. I contacted Target and was sent a refund
