  • takes time to prep it right, but worth it.
Size: Queen Style: 9-12" Deep
I ordered this mattress protector for my boyfreind who had a run-in with bedbugs a few years ago and is still a bit paranoid about it. He had just purchased a new queen sized pillow top mattress a couple months prior, and I figured this would be a good time to protect it and a chance to give him some extra peace of mind. To be clear, about the time this came in, we found what we think was a loner bedbug in or close to maturity, and I had gotten a few bites over the course of a week while staying there and sleeping on the new bed. Between these protectors (I bought one for the boxsprings and one for the mattress), a heat gun, and copious amounts of Diatemacious Earth (spelling? It's a fine dust of super small sharp particles that essentially cut into insects' joints and bodies, killing them), the bug was never seen again. I would highly recommend the dust to anyone fighting bugs, in conjunction with these covers. I would recommend opening the package and examining the seams - all of them, including the zipper - and look over the fabric for any defects. There were several reviews that complained about loose stitching or tears. These are made in huge factories on machines at a ridiculous pace - sometimes things get a little out of line at that kind of speed and scale, so it never hurts to check. Ours were both great. Also, some complained about the 'chemical' or 'plastic' smell. They are a bit strong, but running them through the washer and dryer first, as suggested on the package, takes care of that. We washed the two covers together, with nothing else. Initially, we left them zipped to avoid damage to the fine coil of the zipper, but in hindsight, I would say lust leave it unzipped all the way. When it came to the spin cycle, the closed zippers and the water resistance of the covers created giant flappy water balloons that kept throwing the washer out of balance. We unzipped them to release the water and it was all fine. They will take a ridiculous amount of time to dry. Just keep the heat low, be patient, and take them out to rearrange them in the dryer again to help them dry evenly. Some reviewers wrote about their covers melting or becoming brittle form drying - because they turned the heat too high. Just chill. You had to wait for the thing to ship to your house, waiting a couple hours with the dryer isn't gonna hurt you. We put them both on easily with two people, but with some patience and gracefullness, a single person may be able to do it. Having two people makes it easier to prevent tears in the cover after installing, while moving the mattress back into place. I gifted a protector for boxsprings and a mattress to my boyfriend for his new bed 4 months ago. He had a run in with bed bugs a few years that left him mildly traumatized. If you want a guaranteed rant, just ask him about it - On second thought, don't go there. We don't even go there. But, back to the covers.... I read a lot of reviews - mostly great, and several pretty bad - before purchasing. We had no problems with either of our covers. Here's what we looked out for based on the negative reviews (and common sense): - Check all seams for rips, loose stitches, and the like, one seam at a time so you don't miss anything. - Check over the fabric...all of it...for any rips, snagged threads, holes, or the like. Do this right out of the package so you can use the crease lines to help track your progress. - Run your covers through the washer with a bit of soap to neutralize the 'chemical' smell. Unzip it all the way to prevent the formation of a giant flappy water balloon that with try to strangle the agitator as your washer jumps about like a wild rodeo bull (yep, this happened). Unzip it all the way to prevent damage from the zipper getting pulled open, in case the two sides try to go opposite directions. - CHECK THE HEAT SETTING ON YOUR DRYER - Turn it down so you don't risk melting any of the synthetic materials. If it feels like you're taking a ridiculous amount of time to run it through and you're starting to feel like you're worrying too much, then YOU"RE DOING IT RIGHT! Take it out and fluff it and flip it around to help it dry evenly and (slightly) faster. I think we ran our covers through, like, 4 dryer cycles.... - Have two people to help put it on. It goes fairly easy and quick with a bit of teamwork and a plan, and will help prevent potential snags or rips from tugging. We slipped the cover over one end and slid it into place, then zipped one side before laying it down. We than lifted the zipped side up so we could straighten out the bottom of the cover in order to zip up the other end. Laid it down once more to zip the last side, and put the mattress/boxspring in place. - Be careful with the zipper. Gently tug your fabric into place so that the two sides of the zipper are close to each other and aligned. The zipper is small and fine so it can create a good bug barrier... Be nice to it, and it should zip just fine. Ours did have a couple "sticky patches" where it didn't quite want to zip. Just gently tug and coax the zipper pull, or unzip a ways and try again. If frustrated, walk away. It's not worth potentially busting that zipper after all the time and money you've spent on it thus far. - If you already have bedbugs, understand that this cover is not some magical kryptonite that eradicates bugs by simply existing in the same room. It can only kill bugs trapped inside, on an already affected mattress by trapping them in there until they starve (about a year or something crazy). Diatemacious (sp?) Earth will kill any bug it comes in contact with. Try using this in conjunction with your covers. ... show more

We had several guests over, and we aren’t sure if it was the new neighbors that moved in from out of state (to an adjoined-wall townhouse unit), or our out of town guests, but someone brought in some dreadful bed bugs. Or so we think they are, we have no idea as we never saw them but would wake up with bites on our upper arms and face! We never saw any evidence on the bed or bedding or anywhere so it was pretty frustrating. We tried as much as we could without harsh chemicals as I was worried about the toxicity for my toddler. We started getting bit after they left, and thought they may have hitchhiked on their suitcases when they stayed at an Airbnb. I constantly washed and dried the sheets on the highest setting, laid down some of that Harris bed bug Diatomaceous earth powder (around the perimeter, legs and inside the outlets), and tried to steam the mattress and perimeter- spent hours doing that, and it didn’t seem to help. What seem to help from getting bit at least was lathering on lavender or eucalyptus scented body lotion from Bath & Body, and spraying around the bed with the same essential oils that were slightly diluted . Long story short, I’m not sure if the buggies are still around. But after I had taped up all the outlets and anything that had a small opening around the walls in the affected rooms, and using this bed encasement, we haven’t been bit, and it’s been several months so far. Make sure your bed is away from the walls too! And put a small plastic castor or deli dish under you bed legs, and put some of that D.E. Powder in it, so they will climb in and get trapped in that. Though we’ve yet to see one 🤷🏻♀️. Ok back to the encasement, I bought this one and the GuardMax zippered mattress encasement at the same time for my Queen mattress and box spring. I can’t remember which one I used for what, but they were both easy to put on. I did it by myself, as. 5’4” female, and took less than 5 min each to put them on. Make sure to remove your mattress from the frame, and put it on its (long) side. Then slip the cover on long ways, and slide it top and bottom, and when get about halfway, tilt the whole mattress towards the uncovered side so you can continue sliding the encasement. Just be gentle as you don’t want to tear it, especially when you are laying it back down on the bed frame. We haven’t had any issues with heat or crinkling sounds either. So far it’s been a great investment! I can’t speak to the waterproofness yet, but being bug free so far, we have been quite pleased! ... show more
