Muy buen producto, cubre el colchón completamente y si lo protege, a mi no se me hizo ni caliente ni ruidoso como se menciona en otros comentarios

### ⭐⭐⭐⭐⭐ These covers are easy to put on, they don't crinkle and they work for bed bugs!
*by  on Reviewed in the United States 13 December 2018*

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. :)

Llevo 5 años con este forro y sigue intacto. Ha sido la MEJOR protección contra las chinches.
