Review: Sweet relief. - I discovered I had bed bugs after three months of bites that I thought were allergic hives. I spent hundreds of dollars on doctors and different prescriptions, and after waking up one day completely covered in new "hives," I lifted my mattress on a whim and saw two bed bugs. I have no idea where they came from or how they got there. Nightmare!! I immediately called an exterminator, and he suggested that I encase the mattress and boxspring of my bed, in addition to treating my apartment and meticulous washing and drying of all our clothes in hot water and thorough vacuuming. I spent alot of time researching the different styles of encasements, and decided to buy this brand, based on the reasonable price, but more because of the five-star rating these encasements received from other buyers. I bought encasements for my mattress and box spring, as well as the pillows. I moved my bed away from the wall, and slid Climb-Up traps under each leg of my bed frame. I also dusted all the baseboards, my nightstands, and my dressers with diatomaceous earth. I have a standard mattress and box spring, and these encasements fit almost perfectly (slightly roomy, but not gigantic). They were very easy to put on, and once the sheets went on, you couldn't detect them at all. (Side note, I love how they make my matresses look fresh and white!) They don't make any noise when you're sleeping, have no odor, and since I've encased my mattresses, I haven't been bitten. I admit that bed bugs have left me paranoid and scarred for life. I'm still a little psychotic about falling asleep at night, but I have no reason to be. These encasements truly do what they are supposed to do. I will never take them off, and I will put them on every mattress I ever buy in the future, as a prophylactic measure so that I never have to deal with bed bugs again. If you're in any situation that resembles mine, don't hesitate to choose this brand of mattress encasement. You will not be disappointed.
Review: ... Is keeping our cat from clawing our new box spring - This is an excellent product, even better than I was expecting. The zipper encompasses three of the four edges so that the "encasement" is extremely easy to put on -- and take off, should you want to. The zipper is also "tight," so much so that it's pretty much invisible once it's closed (preventing virtually anything, even very tiny things, from getting to your box spring). I bought this for the new box spring/foundation we've had, as I write, for barely two weeks. We bought the box spring and this encasement, along with a new mattress, for our home bed where bedbugs and other such creatures are not a problem. Instead, I got it in hopes that one of our cats -- who daily was using several corners of our previous nine-year-old box spring as a scratching post -- would stay away from this new box spring due to the VERY tight weave of this encasement. It's working. Roo was, from day 1, far less interested in it, and after systematically redirecting her away from it (she certainly knows what "NO!" means) she is now, instead, using the actual scratching post that's in the bedroom, as our other cats do. Roo is likely not very interested because she can't actually tear the encasement fabric or stick her claws into it in the (to her) same satisfying way she could into the previous box spring. If her claws were very sharp (we keep them trimmed) they might leave pin-point punctures the fabric (she's a small cat, with small claws), but this encasement's fabric is just not tearable. By extension, this encasement must certainly also work to keep out bedbugs, et al, as it's intended. Considering the unusual fabric and zipper, how well this is made, and how much good bedding materials cost these days, the price, I think, is also pretty reasonable.

### ⭐⭐⭐⭐⭐ SafeRest Waterproof Bed Bug Zippered Bags are great so far
*by M***A on July 12, 2013*

The fabric is soft, no odor, no crunchy noise; the zipper is very fine and the pull tab is covered by a velcro tab when the cover is zipped closed. It is relatively easy to cover both the box springs and mattress without help. Fortunately, I covered the box spring first and it took a couple minutes to figure out the best way to do it. After that, the mattress was a breeze (other than the weight of the mattress). I did find one bed bug and a baby on the bottom of the box spring when I lifted it, so was happy I had the covers in hand. It had been a couple days since I vacuumed and washed everything in hot water before the covers arrived so I'm glad I found only the two. The covers will remain in place for a full year. Having read others' reviews, I have all bed frame feet sitting in Chinese carryout containers with lids underneath and boric acid (or you can use diatomaceous earth/DE) dusted in the lid and the cup to keep any stray bugs contained. Both are desiccants. The bed is also 12" away from the wall. I have no idea how these critters appeared other than via adjoining neighbors. I live in a 1942 end-unit row house and several houses in this neighborhood are full of transient tenants. The neighbors have a mattress out for trash pickup as I write this. I originally discovered the problem when I noticed itching on the back of my shoulder and saw brown spots on the sheet just below the pillow. I went online and thought it might be bedbugs. I found quite a few (too many....yuck....gross) plump and squished bugs inside pillow covers that came with a bedspread that I had purchased and were leaning against the wall, so it's a good idea to make your bed an island. It was a great hiding place for them.
