Review this product

Share your thoughts with other customers

Customers say

Customers find the mattress cover to be of good quality, easy to put on and take off, and appreciate its value for money. The cover feels soft to the touch, with one customer noting it stays soft even after multiple washesings, and provides excellent protection against spills and dust. While some customers say it fits perfectly, others find it too big for king-size hybrid mattresses, and while some report it holds up well after a year of use, others mention durability concerns. The waterproof feature receives mixed feedback, with some saying it fully protects the mattress while others report wetness seeping through.

I bought the milliard dual sided premium trifold mattress twin XL. I didn't realize people don't take the factory covers off to prevent possible irritants or fibers, or fiberglass from flying everywhere, including your respiratory system; even if they're washable. Though some other reviews of that product said they had no problems. This was my first trifold mattress purchase, and I took off the cover to wash it, which the company advertised that the cover is washable for my trifold mattress. Though I didn't see any fiberglass strands anywhere and the tag doesn't identify any fiberglass material, I still became itchy on my body somehow. A friend told me about getting an encasement cover for a 2nd layer of protection, especially with fiberglass concerns. This one was Amazon's overall pick with over 118k reviews at the time of this writing. I was concerned that the case defeated the purpose of having a trifold, but there is plenty of space to still have the mattress completely folded up like normal. I purchased the twin XL encasement cover and very thankful I didn't need to go up in size for room to fold my trifold like it's designed. I repurposed my old queen size duvet cover and folded the excess under the trifold for a 3rd layer of protection. I recommend this product. It's well put together and doesn't seem to tear easily. The encasement is nice and soft. I used my duvet cover just for ease of laundry purposes, storage space, and travel.

    I don’t have any pictures because it’s on my mattress; so I apologize
    My assessment:
    1. I thought the price was right
    2. I had purchased a different brand a few years back but the quality of this product is equal or better
    3. Easy to work with (installing)
    4. I put this over my older one for added protection
    5. Zipper worked great and easy
    6. Great “critter” protection!
    What I did notice, and my reason for this purchase, is that they yellow over time (at least 2-3 years later)
    Overall, great quality product and purchase

    These work very well and fit deep pocketed mattresses as advertised. I put one on all by myself and I’m a small person. It was a snug fit but following the steps in the package yielded good results. The encasements are well made - I particularly liked the Velcro closures over the zipper head. They held up well as I worked them over the large mattress. Our dogs bring fleas into the house and while the bugs are repelled by the supplements our dogs are on, they jump to other surfaces like our bed. Yuck! Highly recommend this product.

    I ordered my mattress cover a little big hoping it would fit because most covers are so small.
    When I received my cover not only did it fit it had plenty of room. It went on with the greatest of ease and I have a really thick bed. It was shockingly soft but so functional in being waterproof and also bug proof. A must when you have a ton of kids in the family who visit and small grandkids!
    I showed my daughter and she’s in love with the cover so much she’s ordering one for every bed in her house to protect her kids and the investments of her mattresses!
    Thanks for making a good, heavy duty cover.

    This was bought after a thorough search of the alternatives. The product was used for more than three years before this review🥺🤔😀. The thickness and stretchability are very good. It really protects the mattress from accidental spills. It is comfortably cool under a cotton bedsheet. It is quite with no noticeable noise for a light sleeper. After more than three years of service, durability had been tested for a normal adult use.

    I love this item so much! I have in full size matgress and 2 singles and it has truly helped! This protector is everything I was looking for.

    100% Waterproof: The waterproof feature is fantastic and I bought it because of this. I have 2 little ones, so accidents happens!

    Comfortable Fit: It’s super easy to put on and fits snugly around the mattresses. I love that it covers all sides, so I don’t have to worry about it slipping off during the night.

    If you’re looking for a reliable and effective mattress protector, I highly recommend the Utopia Bedding Encasement.
