    • Serta Perfect Sleeper Mattress Protector

      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

      I purchased this for my new queen-size bed which has an extra deep mattress. It fits perfectly, and you definitely cannot tell that it is a waterproof mattress protector. Excellent value.

    • Mattress pad

      Just another mattress pad. Not much to get excited about. Not good, not bad; its a mattress pad. A little bit too large for the attress which is interesting since theyre the same brand.

    • Like it

      Didn't give it five stars because I haven't tested whether it will be waterproof. Otherwise it fits the bill.
