Features

  • Jersey Knitted Polyester
  • SIZE & DEPTH: This Guardmax Mattress Encasement fits a Queen Size Mattress that measures 60 x 80 x 12. It stretches to fit a mattress with a depth up to 13 inches.
  • JERSEY KNITTED: The Guardmax Mattress Encasement is jersey knitted in order to combine protection with comfort. The TPU Laminate makes the mattress protector fully waterproof and the jersey knitted polyester fabric makes the mattress encasement soft and comfortable to create a relaxing night's sleep.
  • 100% WATERPROOF MATTRESS PROTECTOR: The Guardmax mattress protector does exactly that. It protects your mattress against any and all liquids. Whether it is a drink or urine no liquid spill will penetrate through the TPU laminate membrane.
  • BED BUG PROOF MATTRESS COVER: Many mattress encasements make the claim that they are bed bug proof. Only Guardmax makes that claim and backs it up by being manufactured in an EPA Registered Facility. Our nylon coil zippered encasement is state of the art to ensure nothing gets in or out once the mattress has been sealed shut.
  • ZIPPERED MATTRESS PROTECTOR: The Guardmax Mattress Protector is made with a nylon coil zipper, which will prevent the zipper from trapping or snapping as is the case with other mattress encasements on the market. If there was such a thing as state-of-the-art zippered technology. Guardmax's mattress encasement would be it. It is a zipper made with durability in mind.
  • SOFT AND BREATHABLE: Made from a high quality jersey knitted polyester, the Guardmax Mattress Cover is soft, breathable, and extremely comfortable. Gone are the days of feeling like you are sleeping on a plastic mattress case and welcome to full protection without compromising on comfort.
  • HYPOALLERGENIC: The Guardmax Mattress Encasement protects against dust, dirt, and dander. When you go to sleep on a Guardmax Mattress Protector you don't have to worry about sneezing throughout the night anymore. Sleep allergy free with Guardmax.
  • EASY-TO-INSTALL: You may need two people to lift the mattress upwards, but besides that our mattress encasement easily slips on the mattress 1-2-3 without any troubles or headaches and when you need to take it off to wash it slips off just as easy.
  • EASY-TO-WASH: Simply handwash or put on one quick load and all stains, dust, dirt, and dandruff will fall off with ease.

  • Not stain resistant waterproof cover for bed.
Size: Twin XL Color: White
While this bed liner is a really nice bed liner I'm kind of sad because I expected it to actually be waterproof. It is waterproof I think because it doesn't let water go onto the bed however if you spill something on it it will not wipe off you'll have to scrub it clean like a cloth so essentially you have no less work if you have a mess like in my case where my son makes messes on the bed I have to still clean them and if he throws up on the bed I have to scrub it off with my hands. I think that they should reword it differently. I am super happy with the quality of it though I honestly don't have a reason to send it back it's probably my fault for not doing more due diligence and making sure that it was an actual like latex liner not a cloth liner. It is cloth though the fabric is cloth and you will have to scrub it clean if it gets dirty it does come off pretty good my son threw up red dye throw up all over the bed and I had to scrub it clean the other night. It worked out okay and the stain came up okay. I don't think it went through to the bed either I think that there is a liner that protects the place just before the bed and then the cloth is on top of that to make it soft and comfy for whatever reason someone would sleep on a liner. It's not a horrible concept but honestly it also is not the best. Update **🤣 I ended up buying one for my bed as well. This is not a bad liner at all. The only thing is if you're wanting something that's not going to stain you need to know that you can turn it inside out. Turning it inside out changes everything. I have no idea why they designed it where the cloth side is the outside except for comfort. The latex liner inside is soft quiet just as comfortable and it's just fine the way it is I don't know why it's designed to go on the inside so we flip ours inside out now. As an added bonus because of the cloth being put on the inside and being a bit of a microfiber e kind of cloth it causes a bit of attraction between the bed and the liner so the liner does not slide around on the bed so really this turned out to be such a happy accident. It started off being a terrible by but if you're looking for a waterproof liner this thing can turn out to be excellent if you know what to do. If you turn it inside out the inside is completely waterproof you can wipe it down clean and the cloth layer for the outside will keep it from sliding around on your bed. The sizing seems on par and the zipper seems to be great quality and it has great stretch. Compared to the other liner I had bought before this it is much better honestly I think even if it's got a hole in it it probably wouldn't care like the other one did it would probably take some time. I wouldn't try that out but it's world's better than the simple latex liner. I'm glad I thought of turning it inside out hopefully this can be helpful to somebody else. It truly is a good liner and if you have no worries of having regular spills it's a perfect liner either way. ... show more

  • Good investment ! Helps w spills and bed bugs
Size: California King Color: White
Got this bc we unfortunately found bed bugs! :( Plus I have a 2 yr old that spills her sippy at night and once in w while will wet thru her diaper. The cover Wasn't as hard to put on as I had thought it'd be, it fits pretty good, is slightly loose at the end, not enough to bother anything and probably best, so it doesn't rip or tear easily moving around on and off the bed. I could SLIGHTLY feel the crinkle when first put it on, buy don't notice it much anymore (had a couple weeks) daughter wet thru her diaper cpl nights ago, and soaked my sheets and blanket, which is a good sign, BC usually it soaked into my memory foam/gel mattress . So seems to definitely be water proof, haven't seen if it helps bed bugs stay away yet or not for sure but haven't seen any bites since putting it and the box spring covers on..! Will update when I've had it a while . but so far I think it was definitely worth the purchase Update: 6 mo later- Still very happy with my purchase, it doesn't bother me when sleeping comfortable, I have had my daughter spill on it a couple times, and due to the said bed bug problem, I can't take it off for at least a year to wash it, but is fairly easy to spot wash and keep clean.. As far as the bed bugs I have noticed a huge difference in bites on my daughter & I.. There has been a COUPLE times we did get a bite or two, but I think that was due to them climbing on the bed.. I purchased bed bug intercepters ( these imo are a MUST for bed bug issues) and since I've gotten those along with the cover I hasn't seen anymore bites /or bugs on my bed (purchased same for all beds in our household.. Along w diatomaceous earth, & bedbug spray to kill live ones) tip, make sure and keep all sides of your bed -even top where lay your head, away from walls and keep blankets from touching the floors.. By doing so, you actually cut off their food supply -you- and they die off.. Wash EVERYTHING and /or put in dryer for at least 30 min on high heat as heat kills them.. Hope this may help someone a little, these things can truly give you the worst stress ever.. Esp when your child(ren) are getting bit every night when they are supposed to be able to rest and sleep peacefully.. Praying that the problem is gone and the nightmarish little critters are gone for good! ... show more

  • Great Mattress Protector

This mattress protector is excellent. It fits my queen mattress perfectly and is easy to put on. The jersey-knit fabric is soft and breathable, making it comfortable to sleep on. It’s 100% waterproof, protecting against spills and accidents. The zippered design ensures full coverage, and the nylon coil zipper is durable and smooth. It’s also bed bug proof and hypoallergenic, which is a huge plus. Cleaning is simple; just toss it in the wash. Overall, it’s a great value for the price. ... show more
