PlushDeluxe Zippered Mattress Encasement, Waterproof, Bed Bug & Dust Mite Proof 6-Sided Protector Cover, (Fits 9-12 Inches H) Twin

They actually work! Truly water and liquid proof! Clear winner in my book and I'll go back to them anytime I need another one!

I compared several mattress protectors on Amazon, and ultimately both 2 of these (1 queen, 1 twin) due to dust mite allergies. They arrived 3 days earlier than expected which was great. I washed them upon opening, and will note that it took quite a while to dry them on low, but not a big deal. I used care when putting them on the mattresses, even though the plastic seems pretty sturdy. They fit great. The top is soft terry, so no sound. In fact, I didn't even notice it under my sheets. Very pleased so far.

Love this product. I have a toddler in the midst of potty training, she had an accident the day we bought her a big girl mattress… luckily, we had this mattress protector on it! No leak, the mattress is still as good as new! Doesn’t make and shuffling noises, and washes just fine in the machine. I plan to get more to replace my mattress cover and maybe even the couch cushions! Definitely worth the buy.

Update: I contacted the seller and I got a new encasements in three days(consider I'm not in the US, it was really fast), as I said before, and now I have them in my two matresses. I bought two encasements, twin and full sizes, I put the full size encasement on the mattress and it was really great, noiseless and comfortable, but the twin had defective sewing and I open it about 6 weeks after I bought them, so no chances for return or refund, I'll try to contact the manufacturer and let you know about how it goes their warranty policy

It is fine and what I was looking for. My only problem was that Amazon sent and charged me for 2 when I only ordered 1.
