These covers are easy to put on, they don't crinkle and they work for bed bugs!
Honestly I was afraid these wouldn't be comfy &/or keep bedbugs away. And worse, that they would make my husband even hotter than he is at night, but they are perfect!! I know this is long, but I think its worth the read. So I started on Amazon, I typed in "bedbug mattress covers", & started looking at the options.. I read a lot of reviews, on many products, but they all pretty much had the same thing: some good reviews, (people who seemed to know how to put a cover on & usually didn't have bedbugs), & some bad reviews (people who put it on wrong or didn't treat bedbugs with anything other than covers, which you can't do). The other reviews were almost all about whether the different mattress covers are waterproof. Since I was battling a bedbug issue I didnt care if they were waterproof, but I had caught it early enough so we really needed covers asap to keep the infestation from spreading & to help with isolation of the problem to make it easier to eliminate them completely. Anyways, I looked at about 24 different covers, looked at pictures, read the information about them from companies, & looked at the reviews the most.. None of them were enough to sway me one way or the other. When I came across the Hospitality ones, I almost didn't stop, since the prices are very reasonable. My man said just check them out since he was irritated that I wouldn't just pick one, so I checked them out, read reviews & zoomed in on pictures of the product. As I read the description, I noticed they said "lab tested", so I checked out the lab too, which was legit. So I ordered 2 right away, one for my futon & one for my daughter's twin bed. When they came, they were very soft & the zipper was tiny, that's a good thing because then the tiniest of bedbugs can't get through it. If you don't do research on bedbugs, you won't be able to eliminate them. Plus the eggs & babie are seriously almost completely clear until they feed & grow, & are as small as a grain of salt, so they're very hard to see. Well anyways, like I said the covers were super soft, so that's great. They keep out the bugs. The covers went on super easily. My husband & I put the futon cover on in a matter of 4 mins, together, we didn't even have to lift it up much, just lifted as we slipped it on. It was super easy. My daughters I was able to put on by myself, she has 2 older twin size thin matresses & a foam topper abt 1 inch thick. I was able to fit all 3 of those in the twin size cover I got for her, by myself. Along with these covers, I used all natural spray from Home Depot, & a huge bag of diatomaceous earth. We haven't had any problems since. And although these are not really waterproof, they are very easy to clean with a wet wash cloth and some 409(had to do that 2 days ago when my dog threw up on it), but you could even just use a disinfectant wipe too. They are machine wash or as well, but with bedbugs, its best you leave covers on for at least 12-16 months since they can live for a long time without food. I HOPE THIS ALL HELPED & GOOD LUCK. :)

Great purchase
I am very pleased with this mattress encasement. I have a Full size 14 inch mattress. I purchased the Full XL size for up to 18 inch depth in the mattress encasement. It is just slightly larger than needed but not by much which is much better than too tight with a risk of tearing. To me, it fits perfectly. The deep pockets made it easy to put on. I don’t hear any sound when moving on the mattress either so the sleep quality and comfort are both high on rating. I also have a thin mattress fitted sheet on top. The material and zipper are perfect: strong and thick. The product even has ties to make sure the zipper doesn’t move, together with Velcro patches just in case there are tears. I highly suggest purchasing this mattress encasement even if you have to spend a bit more compared to other options on Amazon. Bravo!

Precaution, Prevention, Defense or Battlefield.
I left this feedback for all the items I purchased and listed here in prevention of BED BUGS. I live in a apartment building. 10 years ago in the city I live in I never heard any mention of bedbugs. Now I hear it everywhere. I purchased the following just as a precaution. Hospitology Sleep Defense System Waterproof/Dust Mite Proof Pillow Encasement, Standard, Set of 2 Hospitology Sleep Defense System Waterproof/Bed Bug Proof Mattress Encasement,80-Inch by 60-Inch, Queen Hospitology Sleep Defense System Bed Bug Proof Box Spring Encasement, 80-Inch by 60-Inch, Queen BEAP 10013 4-Pack Detector Bed Bug Coaster Trap Diatomaceous Earth Food Grade Pest Pistol Mineral Oil I read online many, many, many different suggesting and opinions. These are most popular ideas, and I agree with them. My bed is brand new and I wanted some protection. Every thing listed I purchased on Amazon is good quality and no complaints. I was very nervous the Hospitality Sleep Defense items would have a plastic feel, but it is not the case. The Hospitality Sleep Defense for the pillows and bed have a nice soft and smooth feel to them. They make my bed and pillows feel smoother and softer. They are a good quality and feel like they will last a long time and not rip. They are very big for even the biggest of mattresses or box springs. First of all the Diatomaceous Earth Food Grade box i received is big. I used this for my entire apartment and still have more then half left in the box. Using Diatomaceous Earth Food Grade, and Pest Pistol (online comments are you can also use empty plastic ketchup and mustard bottles) I dusted all long the walls under the carpet (use a dollar store paintbrush to keep it nice and neat), and in some places I lifted the carpet up and sprayed a little on the carpet tacs that hold the carpet in place. You do not have to spray it heavy, only a light coating. Then I took the electrical cover panels and sprayed inside the walls, USE CAUTION, TURN OFF THE ELECTRICAL PANEL SUPPLY. You might want to consider wearing a dollar store face mask, the Diatomaceous Earth Food Grade will blow around a little, if you get carried away with it. Make sure you spray into all holes and crevasses (even in the bathroom) behind the medicine cabinet if there are gaps, in the trimming along the walls, closets, everywhere!!! Every room, every space!!!!!!!. Online reports and comments are that bed bug like hiding behind the medicine cabinet in the bathroom, behind mirrors or photos hanging on walls, dressers, dressers drawers, light shades. I even sprayed a little on my bed frame. Keep in mind, if the Diatomaceous Earth Food Grade gets wet, it is useless and you will have to reapply it. Also note, if you shampoo your rugs a couple times a year, like me, you may have to reapply Diatomaceous Earth Food Grade after your rugs dry. Diatomaceous Earth Food Grade kills all kinds of bugs, cutting into their hard shell bodies and sticks into their joints. This definitely gives me peace of mind when I sleep or laying in my bed during the day. Bed bugs usually feed in the middle of the night, but if they get hungry they will come out all times of the day. Isolate your bed from the walls and the floors. Only have the legs of your bed touching the floor. Keep blankets from touching the walls and floor. Nothing should be touching your walls or floor. ISOLATION! Computer power cords and cell phone cords should not be on your bed when you sleep. Although there are online reports of bedbugs climbing up to the ceiling and falling down/jumping onto beds, I am not that paranoid. Because it is a death sentence for them, they cannot escape or live in the mattress or lay eggs in the mattress because of the Hospitality Sleep Defense. Always make sure you wash and dry your blankets and sheets every week. Dry for at least 20-30 minutes on hot. BEAP 10013 4-Pack Detector Bed Bug Coaster Trap are very strong and very big. I was very surprised! I was nervous, I have a QUEEN size bed with wheels under each leg. But they fit with room to spare. Use the Mineral Oil in the outer trench of the Coasters. Bed Bugs cannot swim in it, they sink to the bottom and drowns them. But dummy me, my queen bed frame has 5 legs, one leg to support the middle of the bed. I used them on my sofa also. Good luck if you find yourself with bedbugs or using these as a prevention and defense. If you do not have the time or energy, you can hire an exterminator which will cost thousands and thousands of dollars. I am the type of person I do not like to use pesticides in my apartment unless I have to. I never use those insect fumigators, they spray pesticides everywhere and you will eventually absorb them into your skin, from the floors and furniture. If you already have bed bugs, I suggest vacuuming every inch of your bed, on your bed, box, and frame head board. Then do your furniture, sofa and recliners. Sofas, couches and recliners are much harder to eradicate bedbugs from, you might want to think about trashing it. Please, before you trash your furniture, damage your furniture so no one else takes it and gets a bedbug nightmare. When you are finished vacuuming, remove the bag, put in a plastic trash bag and TAPE IT SHUT and put outside away from your house in a trash can. They start spraying the Diatomaceous Earth Food Grade everywhere. Bed Bugs are smart creatures, they are very good at hiding until they are hungry. And they will search you out like a blood hound dog. Good luck!

Perfect Fit for My Casper Mattress—Comfortable, Protective, and Reliable!
I was initially skeptical about purchasing this encasement for my brand-new Casper Dream Max mattress; The mattress has a unique design, so I worried the encasement might not fit properly or wouldn’t offer the full protection I needed. However, I’m happy to report that this mattress encasement fits perfectly—I couldn't be happier! The stretchable fabric hugs my mattress like a true glove, with no awkward bunching or shifting, even after multiple nights of sleep. It’s soft, quiet, and doesn’t affect the feel of my mattress whatsoever. I also love how breathable it is—no uncomfortable sweating or clamminess. What really sold me, though, was the peace of mind knowing that this encasement is doing its job. This is the second time I've purchased this exact product, as I had one for the mattress I replaced with my Casper Dream Max. No complaints then and no complaints this time around. It offers all of the non-negotiable features I was looking for in a mattress protector: waterproof, hypoallergenic, and offers a sleep defense system that’s both practical and reassuring. I have a tendency to overthink potential allergens or pests, especially since my dog loves sleeping on the bed with me. Having this extra layer of protection is a game-changer—I can sleep soundly without worrying about dust mite, bed bugs, or any other nuisances. If you’re looking for a mattress encasement that provides true protection without compromising comfort or fit, this is it. I can’t recommend it enough! Highly impressed and feel like I made an excellent investment in preserving the lifespan and cleanliness of my Casper Dream Max mattress.

Good fit but kind of loud
So far it's mostly good - only just put it on the bed so not yet sure if it helps my allergies but if it even remotely does what it says as far as blocking dust mites I imagine it will. It fits my mattress well & was as easy to put on as a thing that fits all the way over your mattress could be, lol. The only thing is it seems like my bed is super loud now, sadly. Like, it just seems to make a ton of noise anytime I move my pillows around and they happen to brush against each other as I'm arranging them when making the bed, etc, and even when I get in the bed and move my feet around or anything it just makes kind of a loud noise compared to before I had this on. Sounds pretty similar to if you were to run your hand quickly over the side of a tent, weirdly, or synthetic fabric coat sleeves rubbing against the body of the coat. Hopefully I'll get used to it and think nothing of it soon. I think I'd rather a slightly noisy bed vs. Allergies, and at least it isn't like a crinkly plastic type of sound, not super loud when slowly adjusting but strange noise if you run anything over it quickly (even with 100% cotton sheets over top of it)

good (AFAIK)
So far so good! I liked that it came with foam tabs for sharp edge protection and is certified against bed bugs. I was able to put it on a 14 in mattress with a 2-3 in foam topper added on top without too much struggle as a single person, and it seems like it’s so deep pocketed I had an inch or two to spare in height. I did nearly pass away when I accidentally got it all the way on and realized it was inside out so, don’t be like me and triple quadruple confirm you have it on correctly with the slick plasticy side IN from the beginning and as you go. I will say their suggestion for how to put it on is likely best if you don’t want to risk tearing it, but I was able to shimmy it on and just shoved my mattress on and off the frame as I went to keep it from snagging. Actually, I highly recommend you actually source help doing this or you’ll risk throwing out your back out, dislocating a shoulder, and tearing the cover. I do not trust the water resistance based on past experience with other mattress encasements so I am using an added water proof topper. I would test it out but I don’t want to clean up any spills, sorry! I recommend (if needed) that you try a test spill with plain water and check to see if it’s dry underneath before trusting this layer alone to protect against spills. With the caveat that if it’s for pee protection (children, pets, incontinence), just go ahead and add another waterproof layer that only covers the top or the top and sides. You don’t want to have to remove the whole encasement after every accident, and in my experience, a waterproof encasement cannot handle high volumes of liquid even if you get to the mess quickly. Can’t speak to the noise too much due to so many layers but I will say I haven’t noticed any crinkling or added noise since putting this on. While it absolutely adds to the retained heat at night overall, putting my foam topper inside it has actually helped cool down my whole set up quite a bit. So if you use a foam topper put it under the encasement layer for a cooler sleep! The review suggestions want me to mention the comfort level… who is laying on this layer… the texture is kind of rough but not that bad (equivalent to my old waterproof mattress encasement from another brand) but I’d personally rather put down literally any other layer, even a towel, before laying directly on it. I cannot feel it through the sheets with the caveat that I use multiple layers (mattress-> Foam topper-> encasement-> fiber fill topper-> waterproof topper-> sheet)* and if you plan to do just encasement->sheet the sound, heat, and texture might actually be noticeable to you (so maybe look for other reviews from people with your set up). I am pretty confused where the zip ties sent with it go? In my mind it would make sense to zip tie two zipper pulls together, but there’s only one. For the life of me I can’t figure out what I’m supposed to zip. Would love to understand what I’m missing here. *i do this setup to protect against pet potty accidents and it is a little hot but very worth it to not have to clean my mattress to the bones every once in a blue moon when she has an accident. (Unfortunately no image because I immediately made my bed lol)

Dog accident? No problem! Phew!
Amazing cover. I bought a few to keep all my mattresses protected, not from anything in particular, but I liked the idea of a keeping my mattresses pristine. I've had these for at least 3 years, and this past week one my dogs had an accident on the bed. Urine soaked through the flat sheet, the fitted sheet, a mattress pad, and I was so bummed to see the encasement also soaked. HOWEVER, when I removed it from the mattress, the mattress was as clean as ever! I was so elated. Certainly an excellent buy for $40 to protect an expensive mattress. I know waterproofness can wear in the wash and depend on the accident itself, so I'll specify that I've washed and dried the encasement as directed just once when I received it, the volume of liquid was pretty significant (likely the full bladder of a 60lb dog), and the accident was discovered within 20 mins or so, so it wasn't sitting for an extended duration (like overnight). The encasement is a pretty good fit and doesn't slip around. Its not something I even notice is on the bed. Its as though it isn't there at all, so its as comfortable as my bed. It is not thick, in terms of being plush, which is perfect. Great buy! Would recommend.

NOT BED BUG PROOF
Does NOT prevent bed bugs as advertised as “bed bug proof.” It just helps them hide better on the mattress protector and between the zippers and hidden corners. They can walk on it freely and are actually able to hide even better, increasing the infestation more than before. I took it and threw it out with the bugs that were on it. The only thing it did was stop them from going into the mattress itself, since the zipper is sealed properly, and it prevents fluids from soaking onto the mattress. That’s the only advantage if you don’t have a bed bug issue. The product is overpriced and not cheap compared to what’s on the market, and the “bed bug proof” claim is not true.

Great quality and easy to put on
So I bought this cause the reviews led me to believe this will be a quality product and it didn't disappoint. The wirecutter pick is actually for their pillow cases, they ripped the mattress protector and didn't give it a pick (I think WC messed up). The instructions said to wash before use to soften it and get rid of smells. It smelt fine and I'm not sleeping directly on it so on it went. After zipping it up there was a huge air pocket in there (good sign, if it holds in air it'll hold out water) so I opened the zipper and squeezed it out. The warranty card says 5 year warranty and to register it but the web link is broken. Overall I would recommend it.
