SafeRest King (Includes Two Twin Extra Long) Size Premium Waterproof Lab Certified Bed Bug Proof Zippered Box Spring Encasement - Designed For Complete Bed Bug, Dust Mite And Fluid Protection 9"

It's very neat. Very white. Exceĺlent stitching and zipper. A little big for the boxspring. Not sure how thick my boxspring is, but at least 7inches possibly 1 or 2 inches more. Its about 10years old. Very fast delivery. Would definitely recommend. It's very easy to put on the matress. The hidden zipper goes all the way around 3 sides of the boxspring.

Love this product. They stand up to their promise. Mattresses are expensive to begin with only makes sense to protect it. Especially if you live in an apartment building where all kinds of people come and go.....bring...taking....roaches....bedbugs....should I go on?

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.

So far works great. Found it to be on the big side.alot of extra material. But better to have more material than not enough. Like the zipper with Velcro on the end

The outer layer is terry cloth and the inside layer is plastic. Since it takes a long time to dry, it is recommended that you completely unzip the mattress protector before you place it in the dryer.
