Emma Comfort Mattress Review: Construction and Design

The construction and design of the Emma Comfort mattress starts with its cover, a mix of polyester and elastane to give it a slight stretch. I found it was soft to the touch and snapped back from a slight stretch easily. The cover is also removable and machine-washable, which can be removed using zippers in a few seconds.

The first layer under the cover is the AIRGOCELL layer, which consists of open-cell memory foam. I found this layer to be conforming as well as temperature-neutral, as heat didn’t tend to build up due to its wicking technology.

The layer under that is the HALO memory foam layer, which has 3 zones and serves as a transition between the softer top layer and the base below. Thanks to the ergonomic support, I felt my weight redistributed and my hips lifted. My shoulders and legs had enough give under them for better cradling and pressure relief.

The supportive core is made of HRX Supreme foam, a unique foam that is made to take on more weight, enhancing durability and support for a longer time. I sank through the top comfort layers to the supportive core, and my body was evenly spread out for optimal spinal alignment. “The top memory foam layer of the Emma Comfort Mattress molds to the body, while the secondary layer creates a more contouring feel. The cradling the Emma Comfort Mattress provides is excellent for pressure relief and spinal support,” explained Danielle Pacheco, a Staff Writer at Sleep Foundation.

In addition, the Emma Comfort also uses a reinforced edge to give you more support when pressure is applied to the edge. I felt the edges were stable while performing my edge support tests.

These features combined are marks of a luxury all-foam mattress, making the Emma Comfort one of the best memory foam mattresses on the market.

Unboxing and Off-Gassing of the Emma Comfort Mattress

The unboxing and off-gassing of the Emma Comfort mattress was a relatively straightforward process, with clean packaging and only 2-3 hours for the initial smell to wear off. This is fairly quick for an all-foam mattress, earning a rating of 9.

What helped speed up the off-gassing process was that I used a well-ventilated room to let the mattress air out. If I had closed the windows and doors, the off-gassing process could have easily taken longer, so this is crucial to keep in mind if you find yourself with a new mattress.

When removing the Emma Comfort from its packaging, I saw it expand relatively quickly once free of the plastic. After about 2-4 hours, the mattress had grown to its full height without divots. The room's temperature plays a role as hotter temperatures encourage faster expansion. The memory foam layers in my Emma Comfort responded more actively as my room had a suitable, warm temperature.

Emma Comfort Mattress Firmness

The firmness of a mattress, especially the Emma Comfort, will be subjective to the person depending on their weight and preferences.

For me, the bed had a fair amount of sinkage and cradled my body. I was cushioned and felt I was more ‘in’ the top comfort layers than ‘on’ them, but still enjoyed proper support and spinal alignment. This even body hug helped relieve the tension in my muscles and was soft enough to earn a rating of 6.5 for firmness.

Cooling of the Emma Comfort

The Emma Comfort can keep you moderately cool, as its AIRGOCELL layer is open-cell and excels at circulating heat away from the body. This is crucial as a good mattress with some cooling technology can mean all the difference between night sweats and comfortable sleep.

From my tests, I recorded a temperature of 31.7 degrees Celsius. This is just under the maximum temperature recommendation of 32.2 degrees and is cool enough to keep you cool. Even though I was hugged in the memory foam layers, I never felt like I would overheat, and my temperature stayed neutral. Considering this, my rating for the Emma Comfort’s coolness qualities would be 8.5.

The Peace Lily, a similar latex model, was just slightly more cooling. The Emma Comfort was hotter by 1.4 degrees, meaning it's still a suitable option for keeping you cool.

Emma Comfort: Sinkage

From my tests, the Emma Comfort had excellent sinkage, measured at 2.2 inches. I felt well cradled in its layers, cushioned by the AIRGOCELL layer, and balanced out by the transition layer and HRX Supreme core below.

Sinkage is essential for a mattress like the Emma Comfort to feel comfortable and pressure-relieving. Typically, sinkage of around 2 inches and more allows the body to be hugged for weight redistribution.

For memory foam, weight redistribution can cause that ‘weightless’ feeling and deliver excellent pressure and tension relief, which is exactly what I felt when lying on the Emma Comfort. Due to this, I gave the mattress a 9 for sinkage.

Emma Comfort: Response

The Emma Comfort Mattress, based on my review, has a lightning-fast response time recorded at 0.1 seconds for a partial recovery and 0.2 seconds for a full recovery. A fast response time like this means the mattress has rapid-response foam that can conform to the body, but quickly springs back, so you don’t feel stuck or sinking in the layers.

While lying on the mattress, I found I had freedom and ease of movement and wasn’t restricted when changing positions while sleeping. The bounce-back speeds were very quick as well. Due to this, I rated the Emma Comfort at a 10 for response.

The Emma Comfort had similar response times to the Peace Lily, a latex mattress we tested. The Emma Comfort was faster by 0.1 seconds, meaning the foam acts incredibly fast.

Bounce of the Emma Comfort Mattress

The bounce of the Emma Comfort Mattress, based on my review, was remarkably high at a total of 11.5 inches.

I measured the initial compression at 4.4 inches, and the rebound was measured at 7.1 inches. This high bounce is mainly thanks to the HRX Supreme foam base, which gives considerable resilience and firmness to the mattress, which translates to good bounce.

While lying down, I found the cradling layers were evenly supporting me. They also had a hint of springiness that made switching positions effortless. Due to this, I gave it a rating of 9.5.

The Emma Comfort performed better than an all-latex mattress we tested, which is surprising as latex is known for its bounciness. The Emma Comfort was 1.74 inches more bouncy than the Peace Lily, likely due to Emma’s core.

Edge Support of the Emma Comfort

The Emma Comfort has a reinforced edge, helping its edge support perform slightly better. When I was testing the edge, my compressions measured at 4.6 inches when sitting at the edge. This is slightly higher than the maximum of 4 inches that mattresses should aim for to have good edge support. However, despite the slight extra sinkage, I never felt I was at risk of falling out or being unsupported.

Lying on the edge helped spread my body weight, making me more even and comfortable. 

Combining these two factors, I gave the Emma Comfort an 8.5 for edge support.

Emma Comfort Mattress: Motion Transfer

The motion transfer of the Emma Comfort mattress is excellent, measuring 3.5 inches for the glass to shake from our compression tests. Motion transfer is crucial for light sleepers to enjoy undisturbed sleep, even with restless partners. 

I took my tests further with the Emma Comfort and tried to gauge the motion-isolating properties myself. Light motions were minor enough to be absorbed by the mattress. I could feel more significant motions, such as getting out of bed, but I didn’t feel it was strong enough to be considered undisturbed sleep.

In short, the Emma Comfort has good motion isolation, earning a rating of 9. “From my tests, the Emma Comfort Mattress is average when isolating motion. It is high enough that most sleepers should be able to sleep without being woken up by a partner when they toss and turn,” said Bridget Chapman, a Certified Sleep Science Coach and writer of Sleepopolis.

Emma Comfort: Performance for Sex

Performance for sex, and if the Emma Comfort is a suitable option for active couples, relies on three things: the mattress’s bounce, edge support, and cooling qualities. The Emma Comfort performed well for the bounce category but not as much for the edge support and cooling categories, earning a total rating of 9. From my expertise, I found that bounce plays the most significant role, so I would still recommend this for couples.

Couples will find freedom of movement and non-restricting bounce that can help them switch positions quickly. However, there may be slightly more sinkage at the edge than some couples prefer, and the mattress may not feel cool enough.

How It Feels for Different Types of Sleepers

The Emma Comfort offers well-rounded comfort. However, it will feel different to sleepers based on weight and preference. Based on the sleeping position, I’ve broken down how the Emma Comfort feels.

For reference, I am an average-weight sleeper.

Side sleepers 

The mix of AIRGOCELL and HALO memory foam layers work together to provide thick, deep, and contouring pressure relief. While on my side, I noticed the mattress cushioned my shoulders without pressure build-up.

The HALO memory foam’s ergonomic make gave more support to my hips, so I didn’t feel any extreme or uncomfortable sinkage. This would suit both lightweight, average-weight, and heavyweight sleepers well.

However, comfort for side sleeping widely varies between sleepers and ther preferences, so looking at your options for the best mattresses for side sleepers in Australia is always a good idea.

Back sleepers

The HRX Supreme foam base does wonders for spinal support, as I felt cradled by the top layers but firmly and evenly supported by the base. This resilience helped keep my spine, neck, and lumbar well aligned, and I was tension-free in this position.

Both lightweight and average-weight sleepers will feel comfortable on the Emma Comfort, but heavier sleepers over 230 pounds may feel the model is too soft.

Stomach sleepers

Testing the HALO memory foam layer and HRX Supreme foam base for stomach sleeping, I felt well supported while on my stomach. Stomach sleepers need extra support to lift their hips, as even the slightest dip can cause the spine to bed out of alignment. Luckily, though, I was comfortable and at ease while on my stomach, with just the right amount of cradling and support. 

Lightweight and average-weight sleepers will likely feel comfortable on their stomach, but heavier sleepers over 230 pounds may fall through the layers too much to feel comfortable.

Other Important Information: 

Other important information to consider regarding the Emma Comfort mattress includes its 10-year warranty, 365-night sleep trial, certifications, and free shipping and returns.

The Emma Comfort comes with a 10-year warranty, shorter than the Ecosa mattress warranty by 5 years. However, it still offers many benefits that gives sleepers peace of mind. The warranty covers manufacturer defects and faults, such as faulty zippers or indents in the foam deeper than 1.5 inches.

If a flaw is found in the cover or mattress, the company will replace either at no additional cost. 

The Emma Mattress also comes with a 365-night sleep trial, which is longer than the Ecosa mattress, which only offers a 100-night trial. That means you can try the Emma Comfort worry and risk-free for an entire year, and still receive a full refund within the trial period if you decide the mattress isn’t right.

The Emma Comfort is CertiPUR-US® certified, which includes all the foams used in the mattress. That means they’re safe from harmful toxins such as heavy metals and are low in VOCs. You can use the mattress in a family setting and not have to worry if the mattress is safe for children.

If a sleeper wants to act on a sleep trial or warranty, the Emma Comfort comes with free shipping and returns. This feature makes it one of the best mattresses in a box in Australia. If you need the mattress to be replaced, you won’t incur any additional fees due to shipping and handling. This does change, however, if you’ve moved addresses. This free shipping offer is similar to the Ecosa mattress, which also does free shipping in certain locations.


From our complete and thorough review, the Emma Comfort mattress certainly has a lot to offer in terms of comfort and sleep quality. With its generous sinkage and fast-acting bounce, this mattress works excellently for unrestrictive pressure relief. I was comfortable on my side, back, and stomach and was reasonably cool throughout the night. Along with its excellent price point, the Emma is a durable mattress that can serve your home for a long time.
