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

Difficult to use
[This review was collected as part of a promotion.] I washed the mattress cover soon as I received it. Drying it takes more effort. The mattress protector is made to be able to insert the mattress into it and zip it up. I personally prefer the kind that I can slip over the mattress like a fitted sheet. It does protect the mattress and conceal the mattress to protect against allergens and moisture.

Thin product
[This review was collected as part of a promotion.] So comfy and soft! Love this item and it’s so durable. It could be a bit thicker but fits great! The entire mattress goes inside and it zips around it for a tight fit.

Good for allergies
[This review was collected as part of a promotion.] This really protects from everything! It’s awesome. I lot of my family members get allergies different times of the year, and I appreciate that this protects against mites, dust, bugs, etc. I’ve also never heard of a product that blocks out bed bugs—this should be at hotels. It’s easy to put on and it stays on thanks to a zipper and Velcro seal. It fit my queen bed well. It’s not something I necessarily thought about purchasing, but now that I have it, I am glad that I do.

Comfort and protection
[This review was collected as part of a promotion.] I really like the AllerEase mattress protection. It fits nicely over my mattress and feels comfortable without being too thick or noisy. It helps keep the mattress from spills, dust and everyday messes while still allowing the bed to feel comfortable.

Durable and cooling
[This review was collected as part of a promotion.] I loved the ease of sliding the mattress cover protector over the mattress and zipping it up. There was a tag that said this side up but the texture of the top is not plastic and it doesn’t sound like crunchy plastic either. It is cooling and very durable with lots of health benefits regarding allergens and bedbugs, also waterproof and moisture wicking.

Fort Knox of Mattress Protection
[This review was collected as part of a promotion.] Really happy with this mattress protector. It zips completely around the entire mattress, so everything is fully enclosed rather than just covering the top. It nice to have a barrier to help keep allergens and dust out, and probably any spills. The material does have a somewhat plastic-ish feel when you handle it, but once it’s on the mattress, you honestly wouldn’t know it’s there. It doesn’t make that crinkly plastic sound, even when moving around. Regular fitted sheets go right over it without any issues, and the bed still feels normal. A great option if you want full mattress protection without changing the feel or sound of your bed.

Max mattress cover protection
[This review was collected as part of a promotion.] Great cover . It's a little bigger than the actual mattress. Easy to apply. The sound of it is a little discomfort because it's like sleeping on a plastic / paper bag .

Fits the mattress perfectly
[This review was collected as part of a promotion.] This mattress cover is very soft. Fit the mattress like a glove and doesn’t make a plastic sound when laying on it. I will say it might take 2 people to put on a bigger sized mattress but I did the twin by myself in no time So far I am very happy with this product and will purchase again.

Super versatile
[This review was collected as part of a promotion.] It was super easy to use. I used it on my sofa instead on the bed. It covered really good and thickness of it is really good and the texture is super easy and it’s not noisy. It was super easy to throw in the washing machine and wash when you first open the bag and I really like that so it’s super easy to take care of. It’s a versatile product. You can use it on anything like a bed or sofa like I need I really like it. Thank you for letting me try it.

Keeps mattress clean and free of any debris
[This review was collected as part of a promotion.] Very lightweight material, texture is sort of a feeling of plastic with a soft touch to it. Seems durable and it comfortable. Gives a slight sound during movement. In all this a decent mattress cover that seals in mattress for full protection 🙌
