We had originally bought a more expensive protector that made our bed so hot and I would wake up drenched in sweat. This protector is cooling you can barely even tell it's on. Will have to see how well it protects the bed, we have a new baby and breastfeeding so that was the biggest concern. Fits our king bed easily.
This mattress cover did its job and while not the best quality, was well worth its money. If you want something that will protect your mattress well and get a good value for your money, look no further. It did make some noise when moving around but not too much.
I purchased this before for my Full size bed (back when the cooling ones were blue) and it's been a godsend for keeping my bed cool during hot summer nights living in the California desert. I just moved out of state to Missouri and with the hot humid summers, I re-purchased for my new King bed and it has been very nice. I love that it doesn't shift and that it fits my deep mattress. Would definitely recommend.
THE BEST WATERPROOF MATTRESS COVER! I HAVE TRIED ALL BRANDS, AND THIS ONE IS BY FAR THE BEST. IT DOES NOT LEAK THROUGH! AFTER MANY PET ACCIDENTS, MY MATTRESS HAS STAYED SPOTLESS. I KEEP MULTIPLES AS A BACK UP FOR EACH BED! ANOTHER PLUS IS THAT IT DOES NOT MAKE A NOISE UNDER YOUR SHEETS, AND IT IS A DEEP POCKET FITTED COVER!
I really do sleep cooler with this on the bed. when you look at it, doesn't seem like you will but it is much cooler then my other mattress protector. good price. don't know how long it will hold up but the price is good and it's keeping me cooler so it's a win. perimenopause is a b!%23ch
Fits awesomely over the mattress ! My kids are hot sleepers and this has helped tremendously with their sleep. Along with mine lol. Also saves the mattress from any accidents!! So saves money too.
This is wonderful for women going through “the change”. I have a grandbaby, there have been some leaks from the diaper overnight, and my mattress never got wet.
I ordered two of these and opened one of them put them on my bed and it was not cooling at all I'd still have one still in the package I want to return due to the poor quality and not cooling like it said
This looked and felt like plastic. I only had to open the box the see if looked and felt like shower curtain material. It looked like it would crinkle every time I moved. Rather than going to all the trouble of unboxing it and putting it on my bed only to have to try and shove it back in the box ifni didn't like it, I chose to simply return it.
This is just a plastic top . Elastic and knit sides. I have a plain mattress not pillow topped and this does not fit. It keeps pulling off. Very disappointed considering the price.
