What reviewers say 💬

This mattress protector has an army of loyal Amazon fans — more than 210,000 five-star reviews — and the testimonials are incredible.

Pros 👍

"I've had enough dog accidents in my life to know when I got my new mattress, I would need a mattress cover... and today was the day," said one pet owner. "I woke up to an awful sound, looked up to see my dog was sleeping behind my husband and suddenly vomited, and it was all over the bed... I was so relieved when I pulled back the mattress cover to reveal a perfectly clean, brand-spanking-new mattress underneath. I will be ordering another just to have a back up on hand. Five stars!"

One customer who said they've had it for four years wrote: "Not only has it protected my mattress several times over the past few years, but last week my husband set a full mug of coffee on the bed, which I didn’t see or anticipate. I then got on the bed, and tipped the entire full mug of coffee on the sheets. Not a drop got through to our mattress! I was so grateful and glad I have them on every bed in our house. I was also surprised the protector worked that well after four years!"

The mattress protector really works to keep things clean, even when you don't notice a mess for a while. "Used these for a vacation rental we rent out, and a guest peed in the master bed and left the sheets and everything on the bed," wrote one home owner. "We didn't find their mess until the next day, due to scheduling, but even with it sitting there 'soaking' the mattress protector did its job, and the mattress was clean and dry, even after that much time."

And a final fan shared: "When my wife was pregnant, her water broke on this bed — Niagara Falls level of water breaking — and it held up. Mattress was bone dry. Don't know how to give a better recommendation than that!"

Cons 👎

Some shoppers think the mattress protector makes them feel a bit warm at night.

One four-star reviewer says it's "comfortable and noiseless" but added: "It does sleep a little warm, so I'm taking away one star. Despite what the advertising says about it being 'breathable,' if there's a plastic barrier that stops liquid, there's a barrier that keeps the heat in and stops air from circulating. That'll be true for any mattress protector. Nevertheless, it's been good so far."

"Tested a small area for waterproofing and it held up with no leaks, and it has deep pocketing that fits our large pillow top mattress with no problems," said another. "It sleeps a bit warm and also the waterproof lining doesn’t cover the sides, which I would have preferred for $40. But overall a good product that does what it advertises."
