Company unresponsive about defective cover. Do not buy.
Tear after first use. Company does not respond to warranty requests. Washed it for the first time about a week after picking it up, and it tore the very first time. I contacted Aller-Ease through their website, at a week old, this was clearly defective. Aller-Ease did not respond at all. I've since replaced with another cover for my kids' bed, and will never purchase any Aller-Ease products again. If the ability to wash it and the warranty are the worthwhile features for you, find something else. That's why we picked it up, and were willing to pay the more premium price for a cover, and both of those were clear failures. Not recommended.

Don't believe all the reviews
I’ve read some of the reviews but this zipper mattress protector and I think these are not real people. I think they’re just trying to make you not buy those mattress. Protector was easy to put on. It says two people need to do it, but I did it and I’m disabled person. It took about five minutes. It didn’t rip I think the material is very well. Made it took about five minutes to put it on zipping it up put it back on the bed and it does what it’s supposed to do. Keep my mattress in case from bedbugs, allergies or whatever else the packaging says go out and spend your $41 and get this. It’s worth the money.

So loud.
It’s SO loud. Any movement at all and it sounds like you’re on the paper covered exam table at the doctors office. It’s also comically loose if your mattress isn’t very deep. It causes our sheets to hang off the bed (6” thick mattress). I wish I had gone with my gut and returned it immediately but we needed a mattress protector asap.

Hello, due to the friction between materials, the presence of any layer of fabric on your mattress will not be 100% silent. However, our product is designed to minimize this effect while maximizing the protective benefits it offers – the prevention of spills & stains from coming into contact with your mattress.

Good idea, work to put on, more than worth the money
This item is a good idea for any matress you have. Although puttin it on takes care and time and is easier with 2 people, its protections are more than worth the money. Recommended product.

Waterproof mattress cover
You literally wrap your entire mattress in this and zip it up. It does feel a little stiff when you first use it. If your goal is to protect your mattress this will do the job

Beware! Your in for pong ride if purchesd
So before starting I knew what I was getting into when I bought this protector. I knew it would be difficult getting it in but felt it was worth the sweat given it was providing full protection. So with that being said I believe I’m owed an apology and refund from the manufacturer. After spending 15 min battling for my life trying to get this protector on I was finally able to conquer the beast and get this own my queen bed by my lonesome. With tears down my face and deeming myself a strong blk women I come to realize that the zipper is broken. BROKEN! I sat on the floor contemplating my life choices. Do I spend another 10 min trying to take this off and return it to the store? Do I continue to sit on the floor giving it death stares and wishing it burn into an array of ashes? Well after a well deserved break and a few glasses of wine I got some super glue and duct tape the itch and called it a day! I would rather sleep on the floor than deal with spending time not only taking this miserable defective overly price piece of plastic off my mattress and going through the process of putting on another one. Was glue and tape the right course of action? Maybe not? But but my back and arms thanks me.

Definately not water proof
Definitely not waterproof, my toddler spilled Gatorade on it and it definitely went through to the mattress. I had bought one before that was actually waterproof which I thought was this one, but it’s not. A bit disappointed as it is pretty expensive.

Horrible quality.
Will not even fit a 10” twin mattress. Does not protect from bugs. Seams are busting in multiple areas. Inner barrier is coming off after first wash.

Full 14” Mattress
It is NOT for a 14” mattress. It does not go on smoothly. It is way too tight and will not zipper shut.
