  • Everything I expected!
    Verified Purchase

    I loved that this mattress pad didn't smell like chemicals or plastic when it came out of the package - I didn't feel the need to wash it to get rid of that factory smell. It is very soft & comfortable, no crinkling or plasticky feel. I got exactly what I expected when reading the product description, and am very happy with this purchase.

  • Best mattress pad we have ever owned

    We bought this because our kids tend to spill drinks on beds and we happen to value our expensive mattress. Almost every mattress pad we had seen was made of polyester or cheap low count cotton. This product is excellent as it is soft, attractive and well made. It is also made from organic cotton and has a great water proof barrier that our kids have already tested. Totally recommend.

  • It works
    Verified Purchase

    We have an older cat that has arthritis and doesn't move fast and tends to have accidents. We purchased a new mattress in January that has a 12 month warranty but any spills or stains will void the warranty. We purchased The Christopher Knight Home PebbleTex Organic Cotton Waterproof Mattress Pad Protector to protect the mattress and it has not disappointed us. The mattress pad has been washed several times now (we haven't used bleach) and dried on low heat setting and it is still holding up. It doesn't make the noise like sleeping on plastic however since it has the protection it does get a bit warm so we just use a lighter weight comforter or bed spread.

  • Gift for our Daughter
    Verified Purchase

    This was a gift for our daughter who has 3 little kids of her own who like to come in sleep with her in the middle of the night......and sometimes haven't stopped at the bathroom on the way to their mom's room. This mattress pad was just what she fits perfectly, is very comfortable and most of all keeps her new mattress safe when there is an accident.

    Definitely waterproof! My dog was sick and peed on the bed it went through the sheets, and when I picked them up it was all on top of the protector. What a relief it didn't go through the mattress! Great product and highly recommend.

    We purchased this a year years ago when one of our cats started leaving surprises on our bed. This mattress pad has worked wonderfully and has held up extremely well in the wash. I would buy it again.
