  • Nice protector.
    Verified Purchase

    I would have given 5 stars, if I had tested the wetness barrier, but I did not. I am, however, depending on its ability to protect against wetness, because I need one in another size for definite wetness protecttion.

  • Love this mattress "protector"
    Verified Purchase

    Have purchased it elsewhere in the past for twice the price. There's absolutely no padding- it is what it says it is, a mattress protector.

  • Serta Perfect Sleeper Mattress Protector
    Verified Purchase

    Cover is supposed to be waterproof and constructed so as not to inhibit "Cool Foam" top of mattress. Hard to tell whether mattress would be cooler without it. It fits well, even though mattress is pretty thick. Cannot tell whether it really is waterproof, as I haven't spilled anything. If I was positive it is "cool" and waterproof I'd have given it an Excellent rating

  • Serta mattress protector
    Verified Purchase

    So far it has saved me from liquid spills, newborn poop explosion and newborns pee. My mattress is still in tact. Highly recommend and does not make noise. Although, in the hot summer days its not cool.

  • Great Product - You Can Sleep On It!
    Verified Purchase

    Really soft and completely noiseless. Not thick so it lets you enjoy your mattress without interference. Looks so nice that you may want to keep it uncovered. Durable.

  • It works!

    Had my first spill today, about half of a can of soda went down. Very pleased to say that my mattress did not have a drop on it. It is very comfortable too. You would never know that the pad is waterproof.
