I am thankful for the reviewer who mentioned this would fit a 10 inch mattress. It does!! I am using this to cover and protect my mattress, underneath a more cozy mattress pad. every other cover is too big and slips around, but this one fits and was easy to put on by myself without ripping it. I will say that it is VERY noisey lol. It doesn’t bother me because I will cover it with a another pad, but be prepared for the swishy crinkle sound of a plastic tarpThis was a replacement for my mattress covering and it did not disappoint. Very durable product & easy to apply.LikeRips to easyZipper broke before we could even get it on the mattressWe got a new mattress and after years of steam cleaning the old one, I decided it was time to be proactive about protecting the new one. I love mattress covers like this, that zip around and encase the entire mattress because it's almost like a second skin. This one in particular sets the standard for any future mattress protectors HIGH. It's made very well, stretchy and breathable, ultra soft top (even though I still will use a sheet to protect it) and the zippers glide easily. It's very comfortable, you really can't tell it's there except for the cotton top adds a small layer of cushion and feels good on the skin if you're not using a sheet. It's really easy to get on with 2 people on either side pulling up at the same time, and easy enough to get off by yourself if needed. Definitely recommend.I have had the same mattress protector on my bed for a very long time.It was large and bulky and made the sheets ruffle in places that made it uncomfortable.Also, it was crinkly and loud, but I thought that was what a protector did."It's ok that it sounds like a bunch of toddlers opening up their candy bars all night. It's protecting the mattress. What's that honey? I can't hear you over the mattress protector. But hey, it's doing its job."Little did I know, there was another way.I also had never heard of a cover that wrapped around the whole mattress.Initially, I thought that was going to make for difficult work on my own with a king-sized mattress, but it really was not too bad. Took about seven to ten minutes of nudging it along and I was quite pleased that the strength of the thing allowed for me to do it as I was worried it would rip.It did not.My bed has not been that comfortable in any recent memory.I really did not think it was going to make that much of a difference, but it did.Comfortable, silent, flat-it did exactly what it said it would do in terms of form factor.I hope not to test it being waterproof, but after feeling the fabric, I am pretty sure it will work there too.Nicely done.* I base my own purchases on customer reviews and seek to thwart "fake" reviews.

Thanks and have a great day!We were a little hasty when we selected this item, and we didn't realize that we were getting a mattress protector that we literally needed to put the entire mattress inside of. That is not a simple task, and it's more than my wife wants to do on her own. She wishes that we'd just gotten a regular mattress protector that goes onto the mattress like a sheet.Once you get past the point above, this is a very well-made mattress protector. The waterproof materials lines the entire inside of the mattress protector--top, bottom, and sides. So, the level of protection is very good here. The zipper seems like good quality, and I believe this will last a long time, based on our early experience with it.No complaints that warrant a star reduction. If you realize what you are buying here, then I think you will be very happy with it.
