So this one has good reviews but I have to say it's very thin compared to other brands. The zip broke but I won't worry about the return; as not worth the cost... and this is used for my dog's mattress. Otherwise I would definitely return the money. Please don't buy if you think it's "waterproof" and will protect your mattress...too thin and the "zipper" breaks every time you try to close it (and mine broke ). There is also a small hole at the seam...so if it's for a child, be sure to buy another brand and make sure it's the best quality. I would for a dog and just want to keep dirt and hair out of the dog bed; as safe; but other than that...don't waste your money and time ordering. I'm really shocked by the reviews, seriously, AND the number of people who have ordered. Yes, most 1 star reviews mention lightning fast and flimsy "cheap" stuff, but I guess that's for those who didn't believe the 1%. I tell you that this is 100% true. I hope this helps you not to make the same mistake I did,
