Fits Securely
Secure zipper, custom-like fit. It takes two to get it on the mattress, but it stretches to fit. We bought the 9-11" for our 10.5" mattress, and the 6-8" for our 7.75" box spring. Our "visitor" traffic went down to zero immediately (floors, drapes also treated chemically).

Everything-proof beyond my expectations!
I put this cover on my brand new Zinus mattress while in the process of moving out of an apartment complex with a bedbug problem. I ordered them at the same time so there wouldn't be any risk of bugs being on the mattress when I enclosed it.So the mattress went straight in immediately upon opening, I moved safely (no bugs in the new house!) and I haven't taken it out in 3 years. Over time, spill happened. A beer got knocked off the side table at one point, various food spills, a couple spots of running dye from bad sheets, whatever. Finally, my cat had an accident on the bed and it soaked the top of the enclosure and I finally decided "Ok, I can't sleep on it until this is taken care of." The cover was looking pretty gross anyway since I had only ever wipe cleaned it...I stripped the sheets and cut the zip tie, fully expecting some of the stains to have gone through even just a little bit. Or at the very least a little bit of the cat pee smell to stick around. I had accepted my fate. The cover comes off and - NOTHING. My mattress is SPARKLING CLEAN. Like brand new, no smell whatsoever. I'm honestly blown away. Bravo, folks. You won me over.The cover's in the wash now. We'll see how it cleans up, but even if I end up ordering another one, I don't care. This was money well spent.Edit: Washed dried and back on the mattress! It's not PERFECTLY white, but it looks clean. Now I've just gotta find another zip tie small enough for this zipper...
