Reviews

Just as advertised

"It's just as expected - fits king, 14" mattress well, good coverage, good feel (haven't tested protection from liquid yet but fabric feels protective. . . ) and No Noise at all. Excellent all around."

— Cecilia R. (5/5)

Try it you might like it

"Great mattress protector but I wish the cooling was just a little cooler but not bad."

— Elissa (5/5)

Its ok

"I noticed a little spot go through to the other side."

— Lisa (4/5)

These products are the best

"These products are the best of the best and remain so when you wash and dry according to labeled instructions."

— Robert J. (5/5)

Not as cooling as I'd hoped

"This matress protector does what it's supposed to. It seems a bit slick on the underside where it contacts the matress and tends to slide around a bit. My disappointment with it and taking a star away is because while it does a good job cooling your body when you first get into bed, once it absorbs the heat from your body it doesn't seem to dissipate it in order to keep you cool. I still wake up hot. Not as hot as with the cheapest matress protector they offer which has no cooling capabilites but still hot."

— Pam J. (4/5)

Just as Expected!

"High quality. Well packaged. Just as expected."

— Heather W. (5/5)

Cool soft bedcover

"I was concerned about potential quirks like noise and texture, but knew I wanted strong protection for my new mattress. So, I gave this a shot. It’s phenomenal, I can’t feel or hear it. It’s soft, cool, and nestles against the mattress so well. Highly recommend."

— Dylan C. (5/5)

— JOHN S. (5/5)
