### ⭐⭐⭐⭐ 







  
  
    depends on whether you need it
  

*by M***Y on Reviewed in the United States on August 20, 2022*

I've never liked to write reviews, but now I feel like I should tell everyone how I use it because I buy things on Amazon by referring to all the reviews to decide which item I need, so if you're just a single bed, I don't  suggest you to buy it because it doesn't work at all if you have a full or queen bed then you can buy the small piece fixer because it does work on my full size bed so can't say this product is not good at all

### ⭐⭐⭐⭐

*by M***I on Reviewed in the United States on September 22, 2022*
