  • Fantastic! Lightweight! Great fit! No synthetic
    Verified Purchase

    This is a great item to have on your bed in case you spill coffee or the kids knock over milk or have an accident. I have it over the mattress pad as I find it so lightweight that under the fitted bottom sheet it cannot be felt! I do recommend this for any bed. Dust and mite proof! A great added protection. Just follow directions and don't wash with bleach as I believe it would break down the protective waterproofing barrrier. Does not in any way feel like a plastic or synthetic mattress cover! Total five stars!!

  • Flimsy
    Verified Purchase

    For $**, this is basically a piece of plastic with some really thin, flimsy-feeling material over it. It has a very cheap feel to it but does look like it would be waterproof.

    This cover is most definetly water- proof. I have a three year old who has spilled juice in my bed more than once and this works perfect!
