Review: Excellent quality encasement - The quality and construction of this mattress encasement is excellent. It is quiet and doesn’t have that plastic sound like some others. The fabric is heavy and tightly woven. Make sure to buy the fit for your mattress depth. Mine fit my 11” mattress perfectly and was easy to put on. The closure is sturdy. It was nice that felt squares were provided to cover any sharp or rough areas they might damage the cover, and that zip ties were provided to lock the zipper closure beneath the velcro flap.
Review: 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.

### ⭐⭐⭐⭐⭐ Precaution, Prevention, Defense or Battlefield.
*by R***N on August 29, 2014*

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!
