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.

This mattress protector is excellent quality! It fits my king-size mattress perfectly with deep pockets that stay snug, even after tossing and turning through the night. The waterproof layer truly works—I tested it and nothing seeped through, yet it doesn’t feel crinkly or uncomfortable like other protectors I’ve tried. The fabric is soft and breathable, keeping the bed cool and comfortable while still offering reliable protection. It also washes and dries easily without shrinking or losing its shape. For the price, this is an incredible value, and it gives me total peace of mind knowing my mattress is protected. Highly recommend!

Basic but quality product. I was renting an apartment in a complex that required all tenants to have a mattress protector. This one was easy to install, lasted the entirety of the two years I lived in that complex, and is in good enough condition that I can reuse it. It's nothing flashy, but it works well, it's comfortable, and it zips shut. You don't have to worry about it sliding down or off like you might with a regular fitted sheet. if you need a mattress protector, this is a great one. If you're not a fan of the slightly slippery texture of the waterproofing, your regular fitted sheet on top will take care of that.

This is definitely what I needed! It’s waterproof, it was but too expensive and it has protected my brand new mattress three times already. It’s really comfortable because it’s really thin and you can’t even tell it’s there. I also love that it just seems like normal fabric, there’s no “crinkle” so I sleep like a baby. I would say that it’s just as high quality as the one my Mom bought for $100.00 a few years ago. I would definitely recommend this waterproof mattress cover.

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.

It is a fantastic fit. Its easy enough for 1 person to put it on. It doesn't sound like your laying on plastic. It is a great price, keeps everything off your mattress including liquid. If I need to I will buy again.
