Many people find themselves struggling with being hot sleepers and find they can’t get into a deep sleep. As The Sleep Advisors, we wanted to put Emma’s Luxe Cooling Mattress to the test to see if this could be the one to improve your sleep. 

With memory foam mattresses, they tend to retain heat but this one claims to adjust to your body temperature. We’ve been impressed with other Emma mattresses so we will discuss how the Luxe Cooling mattress compares to them.

A new Emma mattress could be the solution for you, so let’s find out more.

Who is this product for?

If you’re prone to night sweats, you’ve probably guessed that this cooling mattress is for you. It’s specifically designed with you in mind. This Emma mattress can be suitable for most sleepers, but most definitely anyone who sleeps on their side.

It’s one of the best I’ve tried for this sleep position. I would definitely say it favours comfort over support – that’s not to say there is no support from this one. 

What do we use this product for?

The Emma Luxe Cooling Mattress has breathable properties which is ideal for keeping your body heat to a minimum. It’s also great for a comfortable sleep surface with a soft touch cover. It has the right amount of sink-in softness that you’ll feel your shoulders, hips and knees line up in the correct position.

Does the Emma Luxe Cooling Mattress come in different versions?

With the Emma Luxe Cooling mattress, there's a choice of two. You can either get the standard version or the Plus version. The distinction between the two is the mattress cover you will receive on your mattress.

There is the option of a standard cover or a comfort cover, depending on whether you purchase the standard or Plus version of the mattress. However, the structure of the mattress remains the same in both. There is only a small difference in the prices so it comes down to your preference.

Emma Luxe Cooling Mattress

This version includes the standard breathable cover which is simple, yet soft to the touch and gentle on your skin. It's a great addition to the mattress in order to keep it fresh and clean. The cover is machine washable and hypoallergenic so there should be no concerns for allergy sufferers.

Emma Luxe Cooling Mattress Plus

We received the Plus version which has an upgraded comfort cover. You'll experience the same benefits as the standard cover but with more. It gives extra thickness and plushness, as well as being softer and more durable. So, if you want a little more comfort then it’s worth opting for this one.

Features you should know about the Emma Luxe Cooling Mattress

Being a cooling mattress, you are going to expect to have some carefully designed features to achieve this selling point. As well as this, you will want all the usual benefits from a mattress – whether that's comfort and/or support and extra details.

Here is a pick of a few important elements.

Graphite-infused foam

To ensure you can fall into a deeper sleep, Emma has used premium Thermosync Technology to help regulate body temperature. This is basically a foam layer that has been infused with graphite to provide you with naturally cooling properties. Its main purpose is to remove excess heat and redistribute it out of the mattress. It keeps your body at an optimum temperature so you don't get too hot or too cold. Maintaining your temperature means a deep sleep.

What makes it even better is the fact that it adjusts for each individual so if you’re sharing a bed, it’s based on each body temperature to keep both of you happy. Sleeping can become difficult when one of you is a hot sleeper and the other is not, but this mattress can cater to both your needs.

Overall, this layer keeps you cool throughout the night and promotes an ideal sleep temperature for a good night's sleep.

Halo Memory Foam

Out of all the foam layers, this layer of the mattress is important for both comfort and support. It's Emma's specially designed foam that adapts to your body weight and shape. The zoned support helps to keep your spine aligned and provides pressure relief. You'll feel support on your pressure points – particularly your back – and a soft cradling feel on your shoulders and hips for the ultimate comfort.

Not only is this layer pressure relieving, but it is also breathable. So, the breathability will continue from the cover down to this layer in the mattress.

Anti-slip surface

A subtle feature of the mattress is the anti-slip surface on the base. This is something that many brands will forget about but it can make a difference. The grip underneath stops the mattress from sliding on the bed frame. So, it reduces the chance of it slipping off the side and you having to move it back. Of course, this isn't an issue with some bed frames but ones that don't hold it in place will need an anti-slip base.

Review of the Emma Luxe Cooling Mattress

Person pressing down on the corner of the mattress.

The Emma Luxe Cooling Mattress is a huge upgrade from the Emma Original Mattress. The obvious update is the cooling properties but the overall structure has changed for the better. This mattress is a hybrid model with memory foam and pocket springs.

As for the cover of the Luxe Cooling Mattress, I found it really simple to remove with the zip spanning the whole way around. Unzip it completely, take it off and pop it in the wash – it’s that easy. The zip can be found halfway down the mattress and is easy to find along the green strip.

Now onto materials that can change the whole experience of a product. Being named a Luxe Cooling mattress you would expect excellent breathability throughout the mattress. So, is this something Emma has actually managed to do? Let’s start from the top layer and work our way down to see how they have achieved a cooling mattress.

The top cover uses open-pore fibres which take and release air back to you. This helps to regulate your temperature and, in turn, keeps you cool through the night. This layer is followed by their ThermoSync Technology which we mentioned earlier – the graphite-infused foam layer that absorbs excess body heat to keep you at an ideal temperature. Next, is the Halo Memory Foam layer that can also be found in Emma’s NextGen Mattress. While it contours to your body shape, it is also very breathable too. Lastly, there’s an Aeroflex pocket springs layer that is deep enough to encourage breathability further into the mattress.

What we like about the Emma Luxe Cooling Mattress

There's a lot to like about the Emma Luxe Mattress but we've narrowed it down to our three favourite things that you should take into consideration when looking to purchase your new mattress. Breathability is the main factor but here are a few more:

What we didn’t like about the Emma Luxe Cooling Mattress

As much as we love this Emma mattress, there are a couple of downfalls to the product that we would like to discuss in a little more detail. Here are the negatives that stand out to us:

The common problems with the Luxe Cooling Mattress & how to solve them

One problem I had with the mattress was one of the handles tearing slightly when being lifted. It wasn't too major as the mattress could still be lifted but it's not the best. It was only a little tear and it didn't seem to get worse when lifted again. You won't be lifting the mattress all the time so it isn't a big deal and it won't change your sleep quality. 

To avoid this, I would say make sure there's at least one person either side of the mattress. Be careful when lifting and ensure you lift at the same time with just enough strength.

Emma's customer service and company information

Delivery – Free delivery is standard for all your orders and returns are free within the trial period. The delivery time can vary but you can usually expect it to be dispatched in a week, as I experienced.

From your order to the delivery, you'll have a tracking link, followed by a text of dispatch with a delivery date. Later, you will receive a time slot and a phone call on the day to say they're nearby. This helps to plan your day accordingly. It meant I could work before the mattress came and stop in time for its arrival. Once it was delivered to my front door, I could carry on with my working day.

Payment – They have the usual payment methods, as well as the option to use PayPal. Otherwise, you can opt for the DivideBuy scheme where you pay in instalments. It is great for those who would rather not pay out a large amount of money in one chunk or for less financial pressure with smaller chunks at a time.

Online customer service – For customer service and any queries, you can send Emma an email or you can have a look through their list of FAQs. If you can’t find what you’re looking for, you can always leave us a comment and we can help you out!

Check the alternatives to the Emma Luxe Cooling Mattress

If you're looking to compare the Emma Luxe Cooling Mattress with another option to see what's right for you, then we recommend taking a look at the Simba Hybrid Mattress. They both have a structure of six layers and similar properties. The key feature in both is the graphite-infused foam that has the purpose of keeping you cool.

Not only does this mattress keep you cool but it is also made from recyclable materials and uses less foam. It's definitely better for the environment than the Emma mattress. You will find that it has a washable removable cover and a depth of 25cm.

What makes this product better than some other similar ones?

Person lying on their back on the Emma mattress.

What makes this Emma mattress better than others is its ability to adapt to each individual so it doesn't matter if one of you gets hot in the night while the other is cooler. You'll both remain at an ideal body temperature. Another advantage that sets the bar high for other mattresses is it's an excellent mattress for side sleepers. They will find it extremely comfortable to lie on to improve spinal alignment and reduce joint pain every morning.

Is the Emma Luxe Cooling Mattress eco-friendly or sustainable?

The Luxe Cooling Mattresses are not the most eco-friendly…

While they do have an old mattress removal service which is very useful and allows your old mattress to be fully recycled, there's a lot that could be better. Plus, it does mean paying out an extra £45.

So, good – but not great!

How did we test the product?

Now, to discuss exactly how we test our products. After all, how can you trust our opinion on quality mattresses if you don't know how we got there? On the base level, all the products we review go through the following tests:

When it comes to the Luxe Cooling Mattress, in particular, these are the tests conducted to gauge its quality:

Overall impressions of the product after the testing

To conclude our Emma Luxe Cooling Mattress review, we will give you an overview of the product and touch on any details we are yet to talk about.

Once I received this mattress, I couldn’t wait to see what it was like after knowing the quality of the other Emma mattresses. I started off by trialling different sleeping positions and found it suited all sleepers. It's a comfortable mattress with sink-in softness but I still felt supported from below. To top it off, if you’re a combination sleeper, like me, you’ll find this one practical to sleep on. The structure of the mattress is quick to bounce back so if you often change your sleeping position then the mattress will keep up with that.

We’re a fan of the Emma Premium mattress and this has a similar structure of six layers, however, this one has an even better cooling foam layer on top. If being a hot sleeper is one of the main things you want to have under control then it may be worth purchasing the Emma Luxe Cooling Mattress.

And that’s not all, the Emma Luxe Cooling Mattress has little motion transfer which is great if you’re sharing with a partner. The good edge support in this mattress is similar to their Premium Mattress with the use of foam edging – giving solid edge-to-edge support.

Emma mattresses come with a 10-year guarantee, plus a 200-night trial for you to get used to your new product and see how much your sleep has improved.

FAQs about your Emma Luxe Cooling Mattress

It's quite a long review so it's possible that we've missed some key questions or you might have skipped over the answer to your burning question. In this section, we will answer the common questions asked about the Cooling Mattress.

Is the Emma cooling mattress worth it?

In short, yes. It's worth it for hot sleepers especially and for those who predominantly sleep on their side. While it's a great mattress, it's also fairly expensive so it's up to you to weigh out the pros and cons to see if it suits your needs.

How deep is the Emma Luxe Cooling Mattress?

It's depth is 25cm which is pretty average for a quality mattress.
