Love it

Not using it on a crib mattress. I needed it to cover a memory foam cushion i use to sit on . Now i dont have to worry about the dogs nails tearing it up and it makes it cooler to sit on. Love it. Plus the zipper is large enough to easily put the cushion in .

I like that it fit well was easy to zip and didn't have a lot of wrinkles when it was on. so far it has worked well I am a little concerned about the health then it is and how long it will last but I can't say it won't last for years

This is great and fits 12 inch tall mattresses

This is great and fits 12 inch tall mattresses zippered on sheet is better then a fitted sheet that still slips off this will not slip off its zippered on and the price was less then that other place that delivers with their own trucks starts with an A.
