Snug fitting enclosure
These mattress enclosures work great- They fit fairly snug on a 16" thick mattress, but go on with not too much effort.

Not for mattresses 15” thick or more
There is no way this would ever fit an 18” thick mattress. It doesn’t even fit a 15” mattress. Purchased it for the Helix Midnight Elite mattress, which is 15” thick, and it’s incredibly tight. Way too tight. It compressed the top layer down so much I had to remove it. I’m sure it’s great for mattresses less than 15” thick, but it doesn’t work as advertised.

Two different types
When it first came I got 2 packs, one looked different from the other like it's been open before. It didn't looked used so I guess it was okay. I just thought they were not the same even though I bought two of the same kinds. One was you had to unzipped all around , the other one was it just unzip half way. Both worked okay, it's waterproof. I only had it for a month I haven't washed it so far it's been fine. I gave it 4 a stars because it came two different kind of protectors. But both are working fine for now!

The Product Works GREAT
I'm very impressed with this mattress protector. I have two twin extra long beds but only ordered one first to see if I liked it. I did and it's time to order another one.
