### ⭐⭐⭐⭐ Getting it on.
*by P***N on 22 December 2025*

Somewhat tricky to put on the mattress. There could be better instructions but once you figure "which way is up" it goes on easy.

### ⭐⭐⭐⭐⭐ Recommend
*by S***E on 14 September 2025*

Recommend… Best to pay a little more for this product, than other I had to replace because it tear so easily. I bought this product for my dog bedding because he older now to prevent any leak residual..etc on his mattress. Held up good even after washing. Zipper is sturdy and reliable.

### ⭐⭐⭐⭐⭐ Quite nice
*by C***R on 19 April 2024*

Basically it is what it says it is, it is the size it claims to be, and the quality seems good. I got this to contain my eclectic stack of various inflatable and foam pads into a more consistent mattress-like stack. It looks nice, zips around about 70–80% of a mattress for easy access, and the zip stop area has a velcro closed cover. I use a thick mattress pad cover on top so I don’t know if just using a sheet would be too sweaty. I bought a 2nd one just in case so I don’t have to risk getting a bad one if this one gets damaged.
