  • Bed Bug Mattress Encasement Sealed on All Six Sides: The nylon zipper closure glides around three sides and tucks under a stitched guard flap, leaving no open corner or gap at the pull; sleep tight knowing nothing crawls in and nothing crawls out
  • Jersey Knit Mattress Encasement, Soft and Quiet: The knitted polyester face feels more like a soft T-shirt than plastic, silky smooth and silent as you turn over; the breathable jersey fabric handles a warm wash and low tumble dry and keeps its shape
  • Waterproof Mattress Cover for Spills and Night Accidents: A waterproof layer sealed beneath the knit helps keep sweat, spills, and wet nights off your mattress; ideal for kids still learning, and when a mess happens it unzips and washes like a sheet
  • Dust Mite Mattress Cover and Allergen Barrier: The tight knit and sealed zipper keep dust mite allergens shut inside the mattress instead of drifting into bedding; and rest easier knowing the fabric on your skin is OEKO-TEX Standard 100 certified

Description

Guardmax Mattress Protectors have been around for over 20 years. When bed bugs popped up in the 1990's Guardmax was there; helping protect bedrooms and mattresses from the resurgence. Now with a global resurgence of bed bugs your mattress and bedroom need Guardmax more than ever. However, over the past 20 years Guardmax has evolved and is not just about manufacturing mattress encasements that are bed bug proof. The Guardmax Mattress Cover is also protecting your your sleep with a mattress protector that is soft, breatheable, and 100% hypoallergenic. Read Below to Discover why Guardmax Mattress Protector is the Solution to Your Sleep. Bed Bug Proof The Guardmax Zippered Mattress Encasement has an advanced zipper that is designed to be durable and completely seal upon closure to trap any and all bed bugs. This zipper is also guaranteed to not break for 10 years. Unlike other zippered mattress encasements, our zippers won't snap or trap. We are so sure about that we will replace your product for free if it does break in any way within 10 years. 100% Waterproof The Guardmax Mattress Protector has an outer layer made of soft and comfortable fabric material.

Today, Guardmax uses high quality fabrics to ensure that not only won't the bed bugs bite, but you will sleep on a soft, skin friendly, and comfortable mattress protector. Why are your mattress encasements so expensive if they come from China? Our mattress protectors come from China like many other mattress encasements on the market, but our mattress encasements are the only ones that come from a manufacture with an EPA Registration. This means are claims are actually backed up. Do I need a mattress encasement with deep pockets? Guardmax makes regular sizes mattress encasements, which covers most mattresses and mattress encasements with deep pockets. We recommend you measure your mattress and then look at the size chart we provide in the listing. How are your mattress protectors bed bug proof?

Once you wrap the mattress encasement around your mattress all bed bug in the mattress will be trapped and die. Should I purchase other Guardmax items with this mattress encasement? You don't need to, but it is recommended to at least purchase our Guardmax Pillow Protectors and our Guardmax Box Spring Cover with our Guardmax Mattress Encasements for maximal bed bug protection.

Fits well and works great at a good price.
Size: Full - 12" Deep Color: 1 - White
This high quality mattress cover was easy to install. After airing out for several minutes, there was no noticeable odor. The material is thick but not stiff. It will likely last for years.

Fits amazingly well and is amazingly easy to put on. The zipper is of high quality, and so is the material. I bought this item so that I could temporarily store a king-sized mattress safely from bugs and mice. You could easily put bedsheets over it and sleep comfortably

Needed a mattress pad that wouldn’t move with my dogs when jumping on and off the bed. This is perfect! No more dog fur on the mattress. No noise either! Fit over a pillow top.

Its nice
Size: California King - 12" Deep Color: 2 - Gray
I'm not a fan of mattress protectors, but I keep spilling stuff on my bed... so I tried to get the least "mattress protectory" mattress protector possible.. and this is it. It doesnt bother me nearly as much as others have in the past. It seems like its good quality, and put up with the abuse it took one person to get it on a Cali king purple bed (floppy and heeeeeeeavy), without ripping. The fabric is nice, and its not too thick. There were no weird smells, and its sort of comfortable on its own. I wouldn't mind using it as a a stand alone sheet if need be. Purple beds are tough to beat on their cooling properties, so this does hinder that a little. But not that much. Its super easy to hand clean. It will absorb water into the outter layer, but it wont penetrate through it, which to me is a plus. That way a spill doesnt turn into a flood. Other protectors the water beads up on the surface, and of you move, the water goes with you. Not this one. My only gripe is, when I get up it sucks on air, and when I lay down, the mattresses squishes and the air it sucked in when I got up is trapped momentarily, causing it to balloon up every where, but eventually that air escapes. ... show more

So far so good!
Size: Queen - 12" Deep Color: 1 - White
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 SafeRest zippered mattress protector 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

Secure Mattress Protection That Feels Reliable and Easy
Size: Crib (28" x 52")- 6" Deep Color: 2 - Gray
I have ordered this multiple times for my dog’s beds. This crib size mattress encasement is a really practical way to fully protect the mattress. The zipper closure feels secure and helps create a complete cover that gives peace of mind against spills and everyday messes. The jersey knit material is soft and flexible, so it fits without feeling stiff or noisy. I like that it is both waterproof and bed bug proof, which makes it feel like a strong protective layer for long term use. It goes on fairly easily and stays in place once zipped up. Overall it is a simple but very effective way to keep a mattress clean and protected. ... show more
