Very Nice

MamawAJM June 12, 2026

i bought this because when my great-granddaughter stays with us she sleeps with me. With a new topper on the bed I didn't want itto get ruined if her diaper leaked. It gives me peace of mind and is very comfortable to sleep on. I even forget it's there!

Lindsey June 15, 2026

being on top of the mattress it doesn't alter the comfort or feel of the mattress itself great barrier between mattress and fitted sheet, especially for kiddos who still have occasional accidents

Good fit at a good price.

Elaine June 27, 2026

There's no cushioning to it, but it wasn't advertised as having it. Just wanted a mattress protector at a good price that easily fits my mattress. Got it.

The mattress pad overall is good. The only negative is that it is supposed to fit a mattress up to 13 inches thick. Our new mattress is 12.5 inches thick. There is no material to tuck in under the mattress. The result is sometimes it slips upward and bunches on the top of the mattress.

It does have a cloth feel to the one side with a little bit of padding unfortunately the backside is still just plastic. It is better than the alternative if there is an accident at least you don't have to either try to clean the mattress or throw it away.

Eh

Kristin November 13, 2025

This mattress pad slides all over the place and is hot. I put it on a bed in the spare room , put the sheet on sat down for a few minutes on top and it was hot. Thought I was crazy, so I then sat on the floor and just put my arms on the bed and you can feel the heat radiating not to include the sheets and everything just moved with me..

This is not like anything I've purchased before I have four on different beds already and they were the same brand but they've changed. These are a polyester type fabric really lightweight. Just sleeping out one night. There's poles all over it and I see at the bottom of our feet were it's a hole in it already and I've had it on there since Saturday night. It's now Thursday terrible quality don't buy and waste your money that goodness Walmart good people and they refunded me for it. Also, it is not a lot of proof like it says child peed on the bed and went right through my mattress not happy avoid it.

Typically Walmart Trash

FordF100 March 4, 2026

This mattress protector is the worst quality I have ever seen. Its thin and ripped while putting it on. There is absolutely NO WAY this single-ply toilet paper thin fabric would handle a single cycle in the washer. I HIGHLY doubt its ability to protect my mattress. This will be returned as soon as the one from Amazon arrives. Lord forbid a billion dollar company have an pride or quality behind their own brand. What an absolute disgrace.

tradhy

Mackenzie October 30, 2025

it doesn't stay in place it slides all over the place which defeats the whole purpose of of it being a mattress protector. the part that goes down the side of the mattress is so thin it ripped when i was putting it on the first corner. wouldn't waste your money

NOT WATERPROOF

Dawn June 2, 2026

I bought this specifically because it is advertised as being 100% waterproof and I have a toddler who's potty training. This is NOT water or any type of liquid proof as the protector and my brand new mattress are soaked.
