It works. It's bigger than needed, but, its intention isn't for looks and it does exactly what it describes. I suggest getting a color that's not white. If you're purchasing for bug reasons, it will be easier to spot the eggs.
I got the black covers and they are a very big but after some fixing and tucking I got them to look half easy decent. But it really works!!! They are expensive but worth every penny. Since I’ve put them on I haven’t seen a bug since. I used to spray around the couches and lift it up to make sure they weren’t hiding under and I no long do that anymore. Before I put them on I sprayed the couches too to bottom and then the walls that it sat on. And then encased the couches. I tried so hard to get rid of them but no luck. This is even good for spills. My kids would sometimes fall asleep on the couch and would have accidents so this keeps liquids off of the couch and makes it easier to clean without leaving odors or stains
These encasements are huge. I needed two for a sectional couch that I can unhook into a two piece. Love it. I had a close call with a family member giving me stuff. Now I feel my couches are safe from this epidemic! I didnt have bb in my couch. if my home was ever truly hit, i can declare war with some ease that the inside of my couch will not be infested or affected.
