Review: A really quality item - had never seen one before! My husband and I were able to get it on the box springs and zipped up I washed and dried it according to directions and came out of dryer soft, not wrinkled Very impressed with the material Our box springs fit fine and am impressed with the zipper design It’s nice to have the box springs zipped up and completely covered in clean cover After having this we will always use the encasement - totally covered box springs Am Confident in this purchase!
Review: 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.

*by L***R on 23 May 2015*

I installed this encasement on my box springs, along with the SafeRest mattress encasement, as a preventative measure and deterrent*, so I can't speak directly to how well these keep bed bugs in or out. What I can say is the quality is far superior to the original box spring encasement I purchased (no names, comes in orange packaging). That one was much more cheap and 'plastic-y' feeling and got brittle pretty quickly, which is a problem you don't want to have with an encasement. The SafeRest zipper is very tight and gave me no problems, and the Velcro closure at the end is a good added measure. I did take the measures of softening the metal edges of my bed frame with duct tape to prevent tears and duct taped the corners of the encasement to stop my cats from scratching it, my bed skirt covers that up. The quality seems very good, no tearing, flexible, soft and durable material. Opens on three sides to install, which I did no my own. I just cleaned my floors well, laid the encasement down and open, placed the box spring on top, flipped the top over and zipped it up. Don't try to put the encasement on with the box spring standing on edge or on end if you're doing it alone, it will be an exercise in futility. I work at a college and, because of the dorms, we've been educated about bed bugs. Because of this I might be a bit more cautious than many, but with bed bugs on the rise, I think these are a generally good idea --- especially in urban areas where your'e sharing cabs, trains and buses with the public. Anyone can bring them into a home, bed bugs don't care where you live or how much money you make. While the numbers are still on the human side (I believe something like 20% of households in the US either have had bed bugs or know someone first hand who has had bed bugs), once they're in your home the odds flip, so some forethought can be a good thing. *As with all encasements, you should know that these won't repel bed bugs, it will just prevent them from taking up residence in their favorite place, which is your bed and, most commonly, your box springs.
