Nest Bedding’s new Cooling Mattress Protector will certainly keep you cool – it even feels cold to the touch. The fitted sheet style protector is waterproof and machine washable and dryer friendly.

There seems to be limited information about the new cooling protector I had to dig for some answers. So, is it really worth the $100+ price tag? If you’re a hot sleeper it just might be. Read on for my full review.

Who Is This Ideal For?

Hot Sleepers. The mattress protector is all about cooling you off and, at least in my experience, it really worked. I think this would be a great fit for anyone who struggles to stay cool at night.

I called the folks at Nest Bedding to ask for more information about the technology they use in their protector and how it keep you cool. The person I talked to told me that the fabric contains phase change materials (PCM). In a basic sense, PCM – which you can learn more about here – essentially absorbs your body heat and keeps you cool. Then it will release the heat back to you if you start to cool off too much.

Although it offers a waterproof barrier and general protection for your mattress, it’s really all about temperature regulation and that’s the main reason I would consider it.

Waterproof Test

Many mattress protectors will say they are waterproof but I always like to put it to the test and make sure they meet expectations.

I poured 10ozs of water onto the surface of the mattress protector. This is a lot of water but it mimics a big accident or a very large spill.

I let the water soak into the protector for a couple hours and come back to check for any leaks/dampness/moisture.

When I came back to check on the Nest Bedding Cooling protector, I was surprised to see that the surface fabric had turned from white to a blue color where the water had been absorbed. There is no information about this on the website.

The protector did pass my waterproofing test, there was no dampness, moisture or leaks of any type of the mattress underneath.

According to Customer Service, the color change is in order to notify you that the surface is wet, and should go back to white once it dries completely.

Additional Considerations

Size and Sound: This protector fits mattresses up to 18” deep. This means that the sidewall fabric is fairly lengthy in order to accommodate such a large mattress.

Sometimes this excess material can lead to a poor fit and/or a rustling “noise” if you put it on a mattress that is closer to 10”-14”.

I tested the protector on a 10” Casper mattress. Even though there was extra fabric, the elastic grip around the edging was strong enough to hold the protector firmly to my mattress. I did not experience a lot of loose material or movement.

Smell: As soon as I opened the Nest Bedding box with my protector, I was hit with a wave of a chemical-like smell. I did ask a Customer Service representative if I should be concerned about any off-gassing and they said no. They said that is most likely from the packaging and shipment– it should dissipate within a day or so. It did go away after a few hours.

Feel: This protector has a raised hexagonal pattern in its surface fabric. It is soft and cool to the touch thanks to their temperature regulating technology.

I tested the protector under Casper’s cotton bed sheets. I wasn’t able to feel the pattern underneath the sheets but I think there’s a chance you might if you go with a thinner or more lightweight sheet-like bamboo sheets.

4.5 Reviewer
The Cooling Mattress Protector from Nest Bedding is a good fit for those who are struggling with sleeping hot. The soft hexagonal surface is comfortable but may be felt under thinner sheets. Fits mattresses up to 18" and costs more than $100 for a Twin size which makes it pricey.

Price and Value

Overall, the Cooling Mattress Protector from Nest Bedding will offer solid mattress protection and relief for hot sleepers. Its surface is soft and it fits the mattress snugly so there is no extra room or noise.

There is a slight odor when you first open the package and it is on the more expensive side, $129 for a Queen size mattress protector.

However, after reviewing the protector I feel that it really did help keep me cool and comfortable overnight, so I would recommend it for people who are in the market for a mattress protector that is both cooling and comfortable.
