  • An absolute must have for any bed for any age any place. A MUST BUY
Item Package Quantity: 1 Size: Full
I literally cannot recommend this Moore Haily this is an absolute must have for any and all ages. My mattresses are beautifully protected this protects from allergens any possibilities of getting mold or damage to your mattress also protects from any damage of your mattress from a menstrual cycle or children spelling things any water damage from your house or just daily wear and tear I would never in my life know that this was a waterproof protection I also don’t know anywhere that sells a mattress protector that zips the entire mattress in to protect the whole thing not just the top this is absolutely amazing and I don’t know how I haven’t had one of these the whole time I’ve had all of that mattresses. I will never be using anything but these. They are comfortable. They are a perfect thickness. They are soft. They just really seem like normal sheets, but they have more stretch so they don’t affect your bed quality, especially if you have a memory from you won’t feel like it affects the quality of your mattress being the right squishiness, etc. They do not feel stiff. They are easy to wash. Easy to put on definitely of course we love putting things on with two people. It’s much easier, but you can absolutely put this on with one person. I even do it on a king size bed. I have these on all of the beds in my house and they are all different size beds. An absolute must have great quality and insanely good deal these are so affordable. I don’t know why not everyone is using these honestly. Also, their breathable in the sense where I don’t feel like my bed is overly hot or anything like that they work perfectly and fit seamlessly under my sheets. They’re also not super tight in the way where it makes it miserable to put them on. They’re the perfect fit, and they make it easy to use them.!! I was so worried I’d be struggling to squeeze them in, but they were just absolutely perfection!!!! I could rave about this product all day ... show more

  • Absolutely Perfect!
Item Package Quantity: 1 Size: Short Queen
I always go to the good & the bad reviews. With over 100,000 reviews, mostly positive, this caught my attention. I'm revamping my motorhome and so I am purchasing a lot right now, and I'm sick & tired of reading reviews, hearing a few bad ones, and then saying "next". I'm getting nowhere. Everything has some good & some bad. Nothing is made for everyone. But, I can tell you this. This mattress cover has so far, been everything they are claiming. Read my honest opinion concerning some of their claims. 1. Mattress encasement. I have a short queen mattress and a nice memory foam topper. Looking at this, my son was convinced it was not going to fit. With his help, we stood the mattress upright with the topper, as much as we could and it slid on easily. I measured ahead of time and I needed a 15". It was a perfect 15", maybe 1/2" wiggle room. 2. The fabric. I've not slept on this yet as I am preparing my motorhome right now. So I can not comment on the "noise" that some are complaining about until after I move in. I will update you. But after giving it a quick test, it was so comfortable, that it passed with flying colors, in my opinion. The material felt like it was a high-end hotel sheet. I can only hope the sheets I ordered are so soft. The feel was luxurious. It's not a thick or padded material. But I do not remember reading that in the description either. 3. The zipper. Easy peasy. It zipped right up without a catch. It has one of those little velcro closures to keep the zipper secured. As far as the other claims, time will tell. The longevity, the washing/drying experience. etc. I would recommend this to friends & family. Anyone looking for a quality item at a fair price, this is it. I can only think that some reviewers received the wrong item. Thickness & material wise. Unless I just got lucky and got a great one. This was an easy purchase. Maybe now, I can stop overthinking every single purchase I make haha! Good luck with your shopping. ... show more

  • Good quality. Machine washable. Opening on one end. Mattress to Slide In.
Item Package Quantity: 1 Size: Twin
I purchased this item for my daughter's twin size bed. As this was her first framed bed and at her young age, I was understandably nervous about nighttime accidents and potential damage to an expensive mattress. After reading other reviews, I decided to purchase this item. Here are my takeaways: IT'S EASY TO WASH. I have on many occasions washed this mattress protector after it has been soiled. Each time it has managed to spare the underlying mattress from damage. Just simply throw it in the washer on a cold setting and dry on low. it comes out looking clean and no shrinkage. IT FITS WELL. I was a little hesitant in purchasing this encasement as others, in my experience, can make the bed hot or make a crinkling sound and you are very aware youre sleeping on plastic. That has not been my experience with this encasement. It is not super tight to the mattress. The material doesn't seem hot or noisy. TAKING ON AND OFF. It is a little bit of a challenge to put on and off. You have to essentially slide it on. One end has a zipper (and protector when not in use). I have a twin mattress for this item so it's not too difficult for one person to manage on their own. However, I can image removal for a larger size would be challenging. As this is for a child's bed, changing for laundering is likely happening more for me than for a king size mattress. Being fully encased can make removal difficult but that is kind of the point. Full encasement means better protection. ... show more
