  • I Love This Product!
Size: California King Style: 9-12"
Just replaced my Cal King Waterbed mattress with a special order regular Cal King Mattress for waterbed insert. I wanted to protect the entire mattress because it was sitting on plywood where waterbed mattress used to sit. I decided to keep the waterbed liner to protect the SafeRest mattress encasement which protects the mattress. So far I have slept on it 4 nights...just got my new mattress 4 days ago. I washed and dried the SafeRest Waterproof mattress encasement per instructions provided and it washed and dried beautifully! I placed the encasement on my Cal King mattress and the fit was absolutely perfect...this encasement fits 9"-12" mattress height and mine is 12" this includes the pillowtop. The encasement is not tight nor is it loose where you have extra material. It is a comfortable fit for the mattress. The materials used for this product are extremely nice. The surface material is quiet, soft and it breathes. The micro-zipper is wonderful and at the end covered by velcro. The encasement was very easy to put on and around the mattress considering my mattress sits inside a 9" high frame. For anyone with a regular bed this will be a snap to put on mattress. So far I have not spilled anything, my pets have behaved...lol and I am very happy with this product. I actually feel extremely safe, comfortable and have peace of mind having this particular SafeRest encasement on my mattress. It does come with a 10 year warranty, is machine washable, comfortable to sleep on and is noiseless. I searched through many products before I came across this particular one and I couldn't have chosen better. I highly recommend this SafeRest Waterproof Lab Certified Bed Bug Proof Zippered Mattress Encasement in any size for anyone who wants peace of mind and a solid product. If anyone were to ask me for a recommendation on an encasement this one gets 5 stars. ... show more

  • Comfortable AND Useful
Size: King Style: 9-12"
Imagine how horrified I was to move into an apartment after selling my house, only to have bedbugs turn up! The inspector couldn’t find any evidence of infestation other than the live one I found, so we still don’t know if it was the apartment, the movers, or the used moving boxes my Realtor kindly gave me. Nevertheless, part of the protocol for eliminating them is to use full encasements for the mattress and box springs if I don’t want to throw them out. There was no sign of bugs on them, so I went for the encasements. I have a king size bed with the usual split box springs, so I had to buy three encasements altogether. I wasn’t very picky about the box springs, but the mattress was a big deal. Almost all of the options were not only bug proof, but also waterproof. I had tried a waterproof cover before, but it had such bad heat feedback I threw it out within a week. Not only that, but it groaned and crackled, and was all around a bad purchase. So this time around I did a lot of research and read a ton of reviews, few-to-none said anything about noise or heat. By and large, this cover is the best. It’s important to note that a mattress cover is not the same as a mattress pad. A cover is just a shield with a few bonus features. A pad is a comfort enhancement. Some items want to be both, but I don’t think it’s possible. This is a mattress cover, protector, and in that role it’s a really good one. The tight weave of the fabric protects against allergens and the dreaded bugs. It sports a terry top with the expectation that you wouldn’t need/want an additional mattress pad, but it’s just too thin for me. After I installed the cover, I put on my mattress pad (after washing in really hot water and drying on high, of course), and the comfort level is intact. That is a very important note for me because, as noted, I can’t handle heat feedback. I haven’t noticed any change. The biggest issue I had against it was my king mattress and trying to will it into the cover. I’m just a 50-something short chick. I would have appreciated some tips and tricks included with the package, but I was on my own. Luckily, the zipper is really long, and you have about three-quarters of it being open to work with. My success was found in flipping the mattress up against the wall, unzipping the cover, and spreading it over the boxes almost like a fitted sheet, and dropping the mattress back down a little offset so I could slide it into the pocket of the unopened part without the cover sliding out of place. Then I just zipped it up! Again, this is not a mattress “pad.” The terry top is thin, but snuggly in a pinch. You would be a lot happier with a real mattress pad over it. The value of this is in the dust, allergen, bug properties. The whole thing is tightly woven fabric to keep the heebie jeebies out. Given how long you will keep your bed, and how long this will extend its life, plus that it doesn’t rustle, crackle, crinkle, etc., it’s worth the price. ... show more

  • Works as advertised

Waterproof and durable; does not make a bunch of crunchy noise if you put a mattress pad over it

  • Excellent mattress protector
Size: Full Style: 9-12"
I bought a new full size mattress and wanted to protect it from dust mites and possible spills. I have bought this protector before, and loved it! It is easier to install if you have two people doing it, but can be done by just one person. I find it's easier to lay it on the mattress zipped up then unzip it and slide to the top of the mattress sliding half under the mattress while sliding the other half over the top of the mattress pull the lower half, under the mattress gently, while simultaneously gently pulling the top half then zip up and adjust as needed. There is a waterproof, terry cloth top and the rest is a durable material. It is very quiet when moving when trying to sleep. Some reviews state there was an odor upon opening the package. Neither of the covers we have purchased had any odor. However, if you do have an odor the cover is washable and dryable (low heat). It takes a while to dry though, but be patient. The zipper is tucked and hidden so it won't snag on anything. I definitely recommend this mattress protector ... show more
