It's safe to say that we can all agree that a quality mattress needs a quality cover. On that note, we wanted to take a look at and review Eve Temperature Balancing Mattress Protector and see whether that's a purchase you should make or not.

Who is Eve Temperature Balancing mattress protector for?

Anyone who wants to prolong the lifetime of their mattress can benefit from a quality mattress protector. Well, Eve Sleep took it a little further. They've made a mattress protector that can supposedly help keep you cool during the night. So, if you want to stay cool and have your mattress last longer – this is the product for you.

What do we use this product for?

To be perfectly candid, if you have a mattress that gets really hot, a temperature-regulating mattress protector will only get you so far. So, we'd mostly recommend using this product as a protective cover, even though it will help you sleep a little bit cooler. However, keep your expectations realistic.

Features you should know about the Eve Temperature Balancing mattress protector

Now, what set this mattress protector apart from all the others are a couple of things, with temperature-regulating properties being one of the most important ones. So, let's take a look at some of the features this mattress protector has to offer.

Outlast temperature balancing coating

What makes this mattress protector perfect for sweaty sleepers is the Outlast temperature-balancing coating that is applied to this protector. The information on Outlast fabric is quite vague, presumably so that the competition doesn't manage to replicate it.
However, what we do know is that it is a fabric developed by scientists in an effort to help astronauts stay cool. This technology has been translated into the bed & bedding industry and now we have a 100% cotton cover that wicks away moisture and keeps you cool all through the night.

Cotton cover

This mattress protector is made from 100% cotton, which, as we know, is pretty much the ideal material for all kinds of bedding. The cotton is naturally hypoallergenic, meaning it'll keep away dust mites and all other allergens, allowing you to enjoy a good night's sleep.

Furthermore, a cotton top layer is also quite breathable and helps wick away all the excess moisture sweaty sleepers produce during the night.

Finally, we can't forget to mention that the Eve Temperature Balancing Mattress Protector is also machine-washable and 40°C, can be tumble-dried and ironed on low heat.

OEKO-TEX100 Class 2

Another neat thing about this mattress protector apart from it being super soft, hypoallergenic and machine-washable, is the fact that it is OEKO-TEX100 Class 2 certified. Now, that might not mean anything to you, so let us explain.

An OEKO-TEX100 Class 2 certified product has been tested and proven to be free of harmful levels of more than 100 harmful substances. This guarantees that the product is perfectly safe for human use and consumption.

And, it's not only the fabrics. Everything, including the elastic band, was tested and proven to be free of harmful chemicals and substances.
This is vital when it comes to products that we use for hours on end.

Review of Eve Temperature Balancing mattress protector


Now, for our in-depth review.

As far as quality is concerned – we are not concerned. Everything about this mattress protector speaks of quality. The materials used are top-notch, the protector is super soft and comfortable to lay on and it's safe to say that it'll be easy to protect your mattress with this product. With all this in mind, it's easy to understand why Eve Sleep offers a 2-year warranty on this product.

As far as temperature regulation goes, well, you have to tailor your expectations. As we've said, if you have a mattress that gets very warm during a hot summer night – a simple protector will not be able to do much about it. On the other hand, if you just need a little boost to keep your mattress cool during the night, this just might do the trick.

We did notice some improvements as far as temperature regulation is concerned, but nothing drastic, as was expected.

The overall depth of the mattress protector is 30 cm, so you'll be able to put it over some of the deepest, thickest mattresses out there.

On the other side of things, this is not a waterproof mattress protector, which is something most people desire. So, if you're worried about spills and that's why you're looking to protect your mattress – we suggest you keep looking.

Overall, we'd say that this product could be in the conversation for the best mattress protector.

The common problems with Eve Temperature Balancing mattress protectors & how to solve them

There are a few, but the biggest issue people have is that the protector is not waterproof. So, if you're worried about spills – get a different protector. Other than that, people also complain about the lack of size options and the high price. But, as we've said before – this is a premium product and a product is only expensive if you're not willing to pay for it. As for how you could solve the non-waterproof issue. You can't. Sorry.

Check the best alternative to Eve Temperature Balancing mattress protector

Now, if you're not sold on our Eve Temperature Balancing Mattress Protector Review, you might be interested in this alternative and a bit cheaper option.

Eve Breathe Easy mattress protector

Eve's Breathe Easy is a quilted mattress protector specially designed to keep things cool and add some extra support to your bed.

It is another high-quality mattress protector which also comes with a 2-year guarantee, but unlike our reviewee – it is made from microfibre and polyester.

It is a bit cheaper option, comparing to the one we are reviewing but it is still a highly recommended and praised protector that you will be satisfied with.

What makes this product better than some other similar ones?

The best thing about this protector has to be the overall quality. Eve put in a lot of time to perfect this mattress protector, and it shows. It's very durable, it's super soft, and it feels as premium as you would expect it to be.

How did we test the product?

When it comes to testing a mattress protector, the process is quite simple and straightforward.
Naturally, we began by ordering the product from the Eve Sleep website. The ordering process is very easy, all you need to do is enter your information and the product will be on your doorstep in a matter of days.

One thing to note is, that even though the delivery is free across the UK, you should still pay attention if there are any costs that might apply based on where you live or if you try and schedule your delivery for a particular day.

After a few days, we received the package in perfect condition, so, it was time to put it to the test.

The first thing we've noticed is amazing material quality. The protector feels really premium and luxurious. We did expect it to feel like that, but it's always great when your expectations are met. It is a 100% cotton cover and as far as bedding is concerned – you can't go wrong with cotton.
Next up, this mattress protector comes in the form of a fitted sheet – as they usually do. The elastic band felt sturdy, so even if your mattress is slightly thinner – there shouldn't be any wiggle room or crumpling.

All in all, the product looks more than promising.

Overall impressions of the product after the testing

Overall, we are pleased, but not amazed with the product. It is a very good mattress protector, don't get us wrong. But, for the price – we expected it to be close to perfect, and it's not. It would be pretty great if it was waterproof, but sadly – it's not.

Thankfully, Eve didn't make any false claims about the product and they are very clear about what it can and can't do, so at least that's something. All things considered, we'd give this one a 6.5/10. Maybe a seven on a good day.
