Its totally waterproof BUT also traps moisture in the cover. I went to change mattress cover to only realize my new mattress was wet!!! The mattress cover slips on the whole mattress & zips up trapping body heat/moisture I would not buy this product

[This review was collected as part of a promotion.] This was a great buy. It has given me such relief when going to sleep at night. It feels refresh. I like that it wasn't scratchy or too thick to sleep on. It wasn't uncomfortable to sleep on. It has very high quality and was very durable. Was not hard to to put on my mattress.

I actually got two these, one for my mattress and one for my daughter's. It says it will go on a mattress up to 17" but I doubt that. My daughter's mattress is 14 1/2" and it just went over it and that was with the delivery guys holding the mattress up and helping me put it on. It is nice and encases the mattress and has a material feel to it. I use a less expensive one for the box spring that is mostly a plastic feel but did not want that on the mattress for fear that it will generate heat. The plastic ones are okay if you put them on and leave them alone but the last one I had ripped when I took it off the old mattress. It had been there a while so I guess that is to be expected. Whether this really protects the mattress is anyone's guess but it makes me feel like I've done everything I can do to protect it and keep all the nasty stuff out.

[This review was collected as part of a promotion.] I received this item about 2 weeks ago & put it on the bed immediately. I notice a change within a couple days. No more waking up with a stuffed up head, scratchy throat or itchy, watery eyes. It has been a lifesaver.

[This review was collected as part of a promotion.] This allergy zip bed protector is actually very comfortable. Unlike other protectors this one is very descreet and almost un noticeable which is unlike other brands. I like that u cant feel it under neath ur sheets

[This review was collected as part of a promotion.] So many allergens where we live, we needed a mattress protector for a bed that would help. Seems to be much better. A drink was spilled on the bed last week and the mattress wasnt even touched. Highly recommend this for clumsy parents or small kids.

[This review was collected as part of a promotion.] I bought this mattress cover because I have allergy induced asthma, and it can get serious quickly. So I am doing all that I can to keep common allergens down in my house. When I found out how many allergens can get trapped in a mattress, especially an older mattress like mine I was appalled. And now I understand why I have a runny nose when I wake up. I really like the ease of putting this cover on my bed. Its soft and smooth and goes on easy. Then it zips up, easy as can be. It's washable and it doesn't feel hot at night, which is really important. And using this cover and keeping down mold and dust in my room has really helped my sinuses. I would definitely recommend this to my friends!

[This review was collected as part of a promotion.] My husband says that the waterproof mattress protector is too hot for him. Otherwise it is nice and would do the job. It hasn't had an issue with tearing yet, even with kids on the bed every morning.

I have bought multiple "Name Brand" mattress protectors! I know that the way you laundry the mattress protector depends on how they will hold up! And, if they honor your warranty.....or not!! Laundry instructions are a huge deal! The other company gave specific laundry instructions! Instruction that made it clear you had to follow for them to honor your warranty! But, all that you can find on the Allerease box or insert is (Machine Washable)!! Nothing else! I even checked on their sight! You aren't told not to turn the mattress protector inside-out because the washing machine can destroy the protective coating! Nor the same for the dryer, and also DO NOT dry on the hottest heat setting!! None of this is included! So, when you get it wrong they'll be able to say you washed it incorrectly and that voids your warranty!! This is probably by far the worse instruction of any product that I have bought in a very long time!!

[This review was collected as part of a promotion.] This is a great product. I was fearful that it would going to feel plastic-like and you would be able to feel it through the sheet, but that is definitely not the case. It also isn't too bulky and fits well on a queen mattress. A+!
