Review: ... Is keeping our cat from clawing our new box spring - 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.

## Features

- Contains (2) 39" x 80" x 9" covers to accommodate split box springs; independently lab tested and certified bed bug entry, escape and bite proof
- Surrounds the box spring on all 6 sides with a durable high-grade polyester surface material back coated with a water, bed bug and allergen proof membrane layer (great for those with asthma and allergies)
- Exclusive micro-zipper technology prevents all stages of bed bugs from passing through the zippers teeth
- 360° secure zipper feature prevents accidental openings by sealing the end zipper traveler with a velcro flap
- Machine washable (registered with the fda as a class 1 medical device)
