I had one when i was little, it disappeared after 2 moves. I was having a lot of morning allergies recently and I REMEMBERED the existence of this type of covers.Yeah it works.

### ⭐⭐⭐⭐ 







  
  
    Its all good but too lose. Definitely more than 9 inch
  

*by G***O on Reviewed in the United States 🇺🇸 on December 23, 2022*

I bought a 6 inch twin matress and a 3 inch topper to fit this cover, but it definitely not 9 inch deep and also the width and the height must be too big for twin. Too lose and exactly the opposite of tight.
