This is a wonderful mattress protector that gets the job done. It absolutely prevents stains from leaking through to the mattress. The only thing I don’t like that could be improved is the size and lack of snug fit. It moves a lot but still does the job and is not too hot. It’s very soft and comfortable. Would be 5 star if it had a snug feature or bands to fit under the mattress. Worth it for the price and is long lasting.

Beat Mattress Protector yet!

Size: Queen, Color: White

This is the ULTIMATE bed protector I’ve bought in MANY years! Fits SUPER deep mattress. Has a nice thick fill. Doesn’t have any crinkle sound when you move nor makes you feel “hot” either. Literally waterproof also definitely works at keeping mattress protected especially against a huge amount of water poured on top! Washes and dries well in the dryer without shrinkage or losing any lot or waterproofing. Don’t use any bleach or softener or dryer sheets. Fantastic but and HIGHLY recommend! Doesn’t shift on bed either. Has full elastic type mesh ALL around the side of mattress that goes underneath to hold firmly in place. Order size of actual bed even if you have extended height mattress.

Great fit, good added comfort, long dry time

Size: Twin, Color: White, Size: Twin, Color: White

I got the regular twin size for my toddler’s bed. Before, he had a yellow foam topper (one of the cheap ones) and a mattress protector that barely stretched to the bottom of the mattress. I LOVE that this is such a deep fit so I didn’t need to worry about it coming up a lot. We have a standard size twin mattress. For breathability, it does seem like it might trap heat- it is very warm to lay on the mattress now, but that doesn’t bother us. It is comfortable to lay on the mattress. I don’t think it is as thick as the foam topper we had, but that was expected. For a waterproof topper, it’s a pretty good fluffiness. Washing: Hours fit in our washing machine fine. However, I did have to dry it three times. You can’t dry it with anything else or whatever else is in there gets bundled up inside it. I didn’t take a star off for this because we generally have to run loads a second time in our dryer anyways, and it might be because of the weight that it takes longer to dry. overall, I am happy with the purchase! My toddler’s bed is much more “in place” with the sheets, it’s still comfortable and the cost is worth the money to me.
