Simple bed upgrade
[This review was collected as part of a promotion.] This mattress protector is nice! It was easy to put on, and fits our mattress well. I was apprehensive at first due to the texture, but after a few nights of sleeping on it I got used to it. It makes our mattress feel much cleaner!

Great mattress cover protection for my daughter !!!
[This review was collected as part of a promotion.] I got the AllerEase Maximum Mattress Cover in twin size for my daughter’s bed and I’m very happy with it so far. I want to keep her mattress clean and protected, especially from the little spills, dust, and everyday mess. As a mom with kids, I know accidents can happen anytime, so having an extra layer of protection is always a good idea. It fits her twin mattress nicely and was pretty easy to put on. I had to adjust the corners a little, but nothing too difficult. I also like that it doesn’t make her bed too different or uncomfortable. She can still sleep comfortably without the mattress cover being too noticeable. It’s a simple product, but definitely useful for keeping her mattress in better condition for longer. Overall, I’m glad I got this for her bed. One less thing for me to worry about as a mom !!!

Works well and keeps your mattress clean and dry.
[This review was collected as part of a promotion.] While it can be a bit difficult to put on the mattress the zipper is nice. Theres a velcro tab that covers the zipper to ensure it doesn't snag your sheets. I like that it completely enclosed the mattress top and bottom but it still breathable allowing airflow to keep you cool while you sleep. Its thin but still very durable!

Easy to put on
[This review was collected as part of a promotion.] This mattress protector was super easy to put on the mattress. It wasn’t so tight that I had to fight it. I was able to put it on myself in just a couple minutes. I have high hopes of this protecting the mattress from stains, smells, and dust for a few years. There was a bit of a chemical smell upon opening the package, but it went away after washing the protector. I wish it was made with more natural products.

Thin, soft and durable mattress pad.
[This review was collected as part of a promotion.] This is a zippered mattress protector cover which covers both sides of the mattress the fabric is soft and pliable, similar to a shower curtain. I washed it before using and it really holds up to water. I had to lift out the pad to empty the water stuck inside it. It did not rip which i thought it would with the amount of water held inside the pad. I dried on low heat then let it air dry for a while. The instructions said use two people to put on the mattress. Take that seriously. One person makes it extremely difficult. All said and done my grandson doesn’t have any issues. It’s thin, soft and makes minimal noise.

Functional and simple mattress cover
[This review was collected as part of a promotion.] This mattress cover easily covers our queen mattress without being overly tight. It completely covers the mattress, preventing any damage from occurring. The material is very hardy and feels like it is good quality and the zipper works well. We did notice the bed is slightly warmer feeling with the cover on but a small price to pay with a little one.

Perfect
[This review was collected as part of a promotion.] This project is so easy to use. I love that it has a zipper so you’re not struggling to close it on either side of the mattress like a sheet. It’s not even noticeable that it’s on nor do you hear or feel it moving.

Wrapping paper
[This review was collected as part of a promotion.] I like the concept of it covering the entire mattress because that way I know it’ll never come off. The actual material works well to protect the mattress but it is a bit noisy when sleeping on it. You don’t feel it under the sheets but you definitely hear it.

Broke during install
[This review was collected as part of a promotion.] I got this free to test out and leave a review on influenster. Unfortunately the zipper broke on it, possible that the mattress and topper just were too thick. I think I rather have the kind thats fitted. Since it's easier for on and off if your kid has an accident. It did prove well after a water spill though.

Soft, thick, and quality allegen protection!
[This review was collected as part of a promotion.] I love this Allerease twin mattress cover! My 7 year old has allergies; it was just what he needed to protect his mattress from dirt, dust and other allergens entering his mattress. I love how easy it was to put on and just as easy to come off for easy cleaning. The material was very soft but thick; it didnt feel plasticy or make the bedding uncomfortable after putting it on. 10 out of 10 .....highly recommend!

Well constructed but noisy
[This review was collected as part of a promotion.] Nice deep pockets and well constructed. You do need 2 people to put on a Queen or King mattress. Also, while the top fabric is soft the layer between the cover and mattress makes a noisy plastic sounds d with any movement on the bed. The cover also traps air and creates air pockets under the sheets.

Great mattress protector!
[This review was collected as part of a promotion.] The Allerease Maximum Queen Waterproof Allergy and Bedbug Protection Zippered Mattress Protector is excellent. It was easy to install, and I really appreciate the zippered design. It effectively blocks 99.9% of allergens, and I love that it is waterproof, moisture-wicking, and machine washable. Best of all, it doesn't make any crinkling noise like other mattress protectors.

Easy to use
[This review was collected as part of a promotion.] I have never seen a mattress cover like this. The mattress slides right into the cover and it has a nice zipper to keep it closed and in place. It is easy to put on a twin bed with just one person. It will be easy to keep clean to. Very happy with it.

Undecided
[This review was collected as part of a promotion.] Was a bit loose for our twin. Oh well. Reminds me of the protective covers we would put on our kid’s mattresses to protect them from accidents at night. 🤣 Hard to tell if it works or not, but I’ll be lenient and vote yes.

Best Mattress Protector EVER!
[This review was collected as part of a promotion.] I really love this mattress cover! It’s perfect for my medically complex son’s bed. I love that it zips and covers the entire mattress! Every inch is protected with durable, heavyweight material that keeps allergens, and even the occasional accident or spill, out of his mattress
