Not stain resistant waterproof cover for bed.
While this bed liner is a really nice bed liner I'm kind of sad because I expected it to actually be waterproof. It is waterproof I think because it doesn't let water go onto the bed however if you spill something on it it will not wipe off you'll have to scrub it clean like a cloth so essentially you have no less work if you have a mess like in my case where my son makes messes on the bed I have to still clean them and if he throws up on the bed I have to scrub it off with my hands. I think that they should reword it differently. I am super happy with the quality of it though I honestly don't have a reason to send it back it's probably my fault for not doing more due diligence and making sure that it was an actual like latex liner not a cloth liner. It is cloth though the fabric is cloth and you will have to scrub it clean if it gets dirty it does come off pretty good my son threw up red dye throw up all over the bed and I had to scrub it clean the other night. It worked out okay and the stain came up okay. I don't think it went through to the bed either I think that there is a liner that protects the place just before the bed and then the cloth is on top of that to make it soft and comfy for whatever reason someone would sleep on a liner. It's not a horrible concept but honestly it also is not the best. Update **🤣 I ended up buying one for my bed as well. This is not a bad liner at all. The only thing is if you're wanting something that's not going to stain you need to know that you can turn it inside out. Turning it inside out changes everything. I have no idea why they designed it where the cloth side is the outside except for comfort. The latex liner inside is soft quiet just as comfortable and it's just fine the way it is I don't know why it's designed to go on the inside so we flip ours inside out now. As an added bonus because of the cloth being put on the inside and being a bit of a microfiber e kind of cloth it causes a bit of attraction between the bed and the liner so the liner does not slide around on the bed so really this turned out to be such a happy accident. It started off being a terrible by but if you're looking for a waterproof liner this thing can turn out to be excellent if you know what to do. If you turn it inside out the inside is completely waterproof you can wipe it down clean and the cloth layer for the outside will keep it from sliding around on your bed. The sizing seems on par and the zipper seems to be great quality and it has great stretch. Compared to the other liner I had bought before this it is much better honestly I think even if it's got a hole in it it probably wouldn't care like the other one did it would probably take some time. I wouldn't try that out but it's world's better than the simple latex liner. I'm glad I thought of turning it inside out hopefully this can be helpful to somebody else. It truly is a good liner and if you have no worries of having regular spills it's a perfect liner either way.

Great Mattress Protector
This mattress protector is excellent. It fits my queen mattress perfectly and is easy to put on. The jersey-knit fabric is soft and breathable, making it comfortable to sleep on. It’s 100% waterproof, protecting against spills and accidents. The zippered design ensures full coverage, and the nylon coil zipper is durable and smooth. It’s also bed bug proof and hypoallergenic, which is a huge plus. Cleaning is simple; just toss it in the wash. Overall, it’s a great value for the price.

Would buy again!
Really is waterproof! I have toddlers who've wet the bed overnight, and this really did keep the mattress dry. Easy to use, great quality. Would buy again!

Secure Mattress Protection That Feels Reliable and Easy
I have ordered this multiple times for my dog’s beds. This crib size mattress encasement is a really practical way to fully protect the mattress. The zipper closure feels secure and helps create a complete cover that gives peace of mind against spills and everyday messes. The jersey knit material is soft and flexible, so it fits without feeling stiff or noisy. I like that it is both waterproof and bed bug proof, which makes it feel like a strong protective layer for long term use. It goes on fairly easily and stays in place once zipped up. Overall it is a simple but very effective way to keep a mattress clean and protected.

Good investment ! Helps w spills and bed bugs
Got this bc we unfortunately found bed bugs! :( Plus I have a 2 yr old that spills her sippy at night and once in w while will wet thru her diaper. The cover Wasn't as hard to put on as I had thought it'd be, it fits pretty good, is slightly loose at the end, not enough to bother anything and probably best, so it doesn't rip or tear easily moving around on and off the bed. I could SLIGHTLY feel the crinkle when first put it on, buy don't notice it much anymore (had a couple weeks) daughter wet thru her diaper cpl nights ago, and soaked my sheets and blanket, which is a good sign, BC usually it soaked into my memory foam/gel mattress . So seems to definitely be water proof, haven't seen if it helps bed bugs stay away yet or not for sure but haven't seen any bites since putting it and the box spring covers on..! Will update when I've had it a while . but so far I think it was definitely worth the purchase Update: 6 mo later- Still very happy with my purchase, it doesn't bother me when sleeping comfortable, I have had my daughter spill on it a couple times, and due to the said bed bug problem, I can't take it off for at least a year to wash it, but is fairly easy to spot wash and keep clean.. As far as the bed bugs I have noticed a huge difference in bites on my daughter & I.. There has been a COUPLE times we did get a bite or two, but I think that was due to them climbing on the bed.. I purchased bed bug intercepters ( these imo are a MUST for bed bug issues) and since I've gotten those along with the cover I hasn't seen anymore bites /or bugs on my bed (purchased same for all beds in our household.. Along w diatomaceous earth, & bedbug spray to kill live ones) tip, make sure and keep all sides of your bed -even top where lay your head, away from walls and keep blankets from touching the floors.. By doing so, you actually cut off their food supply -you- and they die off.. Wash EVERYTHING and /or put in dryer for at least 30 min on high heat as heat kills them.. Hope this may help someone a little, these things can truly give you the worst stress ever.. Esp when your child(ren) are getting bit every night when they are supposed to be able to rest and sleep peacefully.. Praying that the problem is gone and the nightmarish little critters are gone for good!

Buy this
Best purchase i have ever made. I will buy one for every mattress in my home if the quality remains the same or gets better. Fit as advertised. Washed and dried no issues. Very comfortable. Does not make any noise or have and weird smells. Also does not create heat.

Its nice
I'm not a fan of mattress protectors, but I keep spilling stuff on my bed... so I tried to get the least "mattress protectory" mattress protector possible.. and this is it. It doesnt bother me nearly as much as others have in the past. It seems like its good quality, and put up with the abuse it took one person to get it on a Cali king purple bed (floppy and heeeeeeeavy), without ripping. The fabric is nice, and its not too thick. There were no weird smells, and its sort of comfortable on its own. I wouldn't mind using it as a a stand alone sheet if need be. Purple beds are tough to beat on their cooling properties, so this does hinder that a little. But not that much. Its super easy to hand clean. It will absorb water into the outter layer, but it wont penetrate through it, which to me is a plus. That way a spill doesnt turn into a flood. Other protectors the water beads up on the surface, and of you move, the water goes with you. Not this one. My only gripe is, when I get up it sucks on air, and when I lay down, the mattresses squishes and the air it sucked in when I got up is trapped momentarily, causing it to balloon up every where, but eventually that air escapes.

So far happy with this mattress cover.
I had intentionally ordered the slightly taller height as I was worried about shrinkage after washing. Impressed with the item's quality, which has not moved at all, I will re-order this mattress cover again with, of course, the correct size when the time is right.

Excellent Matress Cover
This mattress cover fit the sofa bed perfectly. It seems very durable and I love that it is waterproof and bed bug proof. It does not have a quilted top, so if that is what your looking for, this is not the cover for you. There is no crinkling sound while lying on it and it completely encases the mattress with a Velcro tab over the zipper end for extra bed bug protection. It is just what I was looking for and am very pleased with the purchase.
