Peace Lily Mattress

The Peace Lily Mattress prides itself in being one of the few mattresses in Australia that is sustainable, comfortable, and affordable. All too often, though, latex mattresses have all the hype but never seem worth their expensive price tag.

That’s why I will break down the Peace Lily Mattress in an honest review today. We will look at how comfortable it is, its durability, its support, and whether its price is worth it or not.

Let’s dive in.

Peace Lily Mattress Review: Construction and Design

To start our review of the Peace Lily Mattress, I will break down the construction and design of this all-latex mattress. It uses an organic cover that I noticed was soft and breathable, with horizontal quilting for moderate softness. It has sewn-in handles for easy movement, which is helpful as latex mattresses like the Peace Lily are usually on the heavier side. The cover isn’t removable, so I had to remind myself that using a protector with this mattress would be better in the long run.

Under the cover is three layers of latex. The first latex uses 2 inches of Dunlop latex at a 65 density, which gives it the soft responsiveness that latex is known for. I was able to sink through this layer and be pleasantly buoyant with moderate sinkage.

The second layer is the core of the Peace Lily, with about 4.5 inches of highly dense latex, rated at 80 for density. This gives the mattress stability and sturdiness, and I felt my hips adequately supported by this layer for proper spinal alignment. 

The last layer is another 2 inches of Dunlop latex with a density of 75, which makes it slightly firmer than the first layer. I noticed less sinkage on this side, with more of a focus on keeping my hips, lumbar, and spine aligned.

The Peace Lily’s design allows both sides to be used depending on your preference, making it a versatile latex mattress. I was more cradled on the softer side, while the firmness of the other side helped keep my back tension-free.

Unboxing and Off-Gassing of the Peace Lily Mattress

The unboxing of the Peace Lily mattress was a pleasant experience, as it comes waterproofed via plastic in a box with wheels. It didn’t take long to expand, and I could use the mattress after 1-2 hours. 

I laid the mattress out in a well-ventilated room, but as it is free of harmful toxins or chemicals, it has no off-gassing. The most I noticed was a slight smell of natural dry grass, which is much better than VOCs any day.

Considering this, I would give the mattress a 10 for off-gassing, as it excelled in this category.

Peace Lily Mattress Firmness

The Peace Lily offers two different firmnesses. I tested its medium firmness first and noticed how buoyant and pleasantly sinking it felt. Latex is not as conforming as memory foam, with noticeably more bounce. I still felt well-cradled, and the layers made me feel comfortable on my side and back. This side feels like a 6.5 for firmness.

The firmer side offered less sinkage, so I was more ‘on’ the mattress than the softer side. However, the firmness did an excellent job keeping my spine straight and level and melting any muscle tension. I rated this side as a 7 for firmness.

Combining the two firmnesses, the Peace Lily earned a 6.5 overall.

Cooling of the Peace Lily Mattress

The Peace Lily has excellent cooling due to its perforated latex layers and breathable cover. From my tests, I recorded a temperature of 30.3 degrees Celsius, which is cool enough to disperse most heat build-up. I felt pleasantly cool while using the Peace Lily, even on its softer side with more body hug, earning a rating of 9.

The Peace Lily is a good option if you’re sensitive to hotter temperatures, making it a suitable mattress for hot sleepers in Australia.

Peace Lily Mattress Review: Sinkage

Sinkage is crucial for a mattress’s overall comfort, and the Peace Lily performed moderately well in this regard.

I recorded a sinkage of 2.01 inches on its medium side and 1.87 inches on its firm side. This is enough sinkage where The mattress cushioned me with enough sinkage to redistribute my weight. At the same time, I was well-supported on both sides. Looking at the compressions, I would rate the sinkage overall at 9.

The latex causes more bounce-back and support for this type of mattress, so there’s a bit less sinkage than what I see from other mattresses.

An example would be the Emma Comfort, where the Peace Lily was firmer by 0.19 inches, looking at the medium side.

Response of the Peace Lily Mattress

Latex is known for its incredible springiness, so the Peace Lily performed very well in the response category. From my response tests, the Peace Lily had a bounce-back speed of 0.2 seconds for a partial recovery and 0.3 seconds for a full recovery. This kind of response made me feel unrestricted while changing from my left to right side on the bed. Overall, a quick response time like this earned a 10.

Interestingly enough, as a memory foam mattress, the Emma Comfort is one of the few mattresses able to keep up with the Peace Lily in this regard. The Peace Lily was slower by 0.1 seconds for its full recovery than the Emma Comfort.

Bounce of the Peace Lily Mattress

All-latex mattresses tend to have excellent bounce, as I determined from testing the Peace Lily. I recorded a bounce of 9.76 inches on its firm side and 9.01 on its medium side. That means both sides will work similarly, and I felt unrestricted while shifting positions. I rated it at a 9 for bounce.

Latex responds similarly to coils or hybrid mattresses with a natural spring that can offer better freedom of movement than slow-adaptive memory foam. Rapid response foam, like the Emma Comfort, may perform better than latex. The Peace Lily had 1.74 inches less bounce on its firm side than the Emma Comfort.

Edge Support of the Peace Lily Mattress

The edge support of the Peace Lily is moderate, which I recorded at about 4.01 inches on its firm side, and 4.30 on its medium side. These compressions are just slightly over the maximum depth that edge support needs to feel like a stable surface. From my tests, I noticed some compressions at the edge. However, I never felt I was at risk of falling out of bed. Considering this, I would rate the Peace Lily as an 8.5 for edge support.

This is similar to the Emma Comfort, where the Peace Lily was firmer along its edge by 0.59 inches, and both attained similar scores of 8.5.

Peace Lily Mattress: Motion Transfer

Motion transfer is how much movement travels across the bed, affecting how easily a partner can sleep. The Peace Lily performed moderately in this category. Due to its springiness, latex has more motion transfer than a memory foam mattress.

From my tests, I noticed motion 8 inches away from the glass. That means the mattress may absorb minimal movement, but you may feel more significant movements. From my tests, I could feel it when my partner was getting in and out of bed, so there could be minor disturbances while sleeping. Considering this, I rated the Peace Lily an 8 for motion transfer.

Peace Lily Mattress: Performance for Sex

Performance for sex is gauged by combining Sinkage, Edge Support, and Cooling scores. These factors determine how effective the mattress is for active couples.

The Peace Lily performed well for sinkage and cooling, and moderately well for edge support, making it a good choice for active couples. I found the latex's ease of movement and springiness especially helpful and rated it a 9.

How It Feels for Different Types of Sleepers

Different sleepers, depending on their weight and firmness preferences, will feel different in terms of comfort, especially for all-latex mattresses like the Peace Lily. I’ve given my experience in every sleep position for this mattress blow. As a reference, I am an average-weight sleeper.

Side sleepers 

Sleeping on my side, I was well-balanced by the higher density latex on the firm side, and didn’t notice any pressure build-up. The medium side had more cradling, albeit not as cradling as memory foam. I felt a lot of buoyancy and was well-cushioned on my shoulders and hips. This would feel cushioning enough for light, average, and heavy-weight sleepers, and can be considered one of the best mattresses for side sleepers in Australia.

Back sleepers

On my back, I sank down through the initial latex layer on the medium side and felt my hips get caught by the core latex layer below, effectively keeping my body even. My muscles were free of tension, and I was comfortable without feeling ‘stuck.’ The firm side was similar, with less sinkage and more support.

This mattress would evenly suit light, average, and heavy-weight sleepers due to this excellent support.

Stomach sleepers

Stomach sleepers need extra support for their hips to feel comfortable. I noticed my spine and hips were well-supported on my stomach, though I could have used slightly more firmness on the medium side. The firm side performed better in this case. 

This mattress can evenly support light and average-weight sleepers on both sides. However, heavy-weight sleepers may want more support, so their hips don’t sink down too much, causing a misaligned spine.

Sleeping Positions: Summary

Sleeping PositionMy experience
Side SleepersI was comfortable on both firmnesses, with the medium side suiting my preferences more.
Back SleepersI felt my spine was well-supported while on my back, with the firm side giving better support.
Stomach SleepersI could have used a bit more support on the medium side for stomach sleeping. The firm side was better at supporting my hips and lumbar.

Other Important Information 

Other important information to consider regarding the Peace Lily mattress includes its free shipping and returns, its 25-year warranty, its 100-night sleep trial, and its certifications.

Similar to the Emma Comfort, the Peace Lily has free shipping and returns to most areas in Australia, making it one of the best mattresses in a box in Australia. This means you don’t incur any additional fees for ordering or returning a mattress within its trial period.

The Peace Lily mattress comes with a hefty 25-year warranty, longer than the Emma Comfort mattress’s warranty by 15 years. This warranty covers defects such as a visible indent deeper than 1 inch. Defects must be acquired through a fault in the mattress, not by using an incompatible base.

In the first 10 years, you have complete peace of mind with your Peace Lily, as the company will cover any defects incurred. In the years after, the company will replace the mattress at a prorated amount. This prorated amount starts at 50% of the original amount, meaning you only have to pay half the original mattress's price to deliver a brand-new one. The prorated amount increases by 5% every year after that, so you’re still somewhat covered. 

Replacing the mattress under warranty would still be more cost-effective than going out and buying a new one, even in the 21st year of the warranty. Long warranties like this also give you peace of mind. A long warranty means the company is confident in its product’s longevity.

The Peace Lily comes with a 100-night sleep trial. Although this isn’t as long as the Emma Comfort, which has a 365-night sleep trial, 100 nights are still long enough to test the mattress, break it in, and see if it’s the right fit for you. If it isn’t, the free returns policy and return it within the trial period can ensure you can try it risk-free.

The Peace Lily also has numerous certifications, such as its eco-INSTITUT® and GOTS certification. These certifications are a bit different from the Emma Comfort mattress, as the Emma Comfort’s certifications ensure its foams contain as minimal harmful components as possible. The Peace Lily, on the other hand, is proudly toxin-free.

The Peace Lily’s GOTS certification means its cotton is 100% organic and chemical-free. Its eco-INSTITUT® certification means the Peace Lily’s latex is free of contaminants, heavy metals, or other toxins. That ensures the Peace Lily is a non-toxic and safe mattress for you, your partner, and your family.


The Peace Lily has a lot to offer you in terms of comfort, quality, and excellent craftsmanship. Its two sides help increase the mattress's longevity, as you can alternate both sides. Plus, the high-density latex core further increases the mattress's longevity and durability as it can handle more pressure. Its medium side works great for comfort and contouring, while the firm side supports the spine and keeps you in healthy alignment. I noticed how buoyant and pressure-relieved I felt while lying on the Peace Lily for my tests.

From my review of the Peace Lily Mattress, I have found it’s suitable for a variety of sleepers. Fans of latex and organic materials will like this mattress the most, and sleepers who want to take advantage of the Peace Lily’s cooling components or bouncy, responsive nature.

The construction and materials aim to offer a balanced feel, making it suitable for a wide range of sleeping preferences.

  2. Are there any specific benefits or drawbacks to the edge support of the Peace Lily mattress you’ve discovered in your review?

    1. In my review, I found that the edge support of the Peace Lily mattress is moderate. On its firm side, I measured a compression of about 4.01 inches, and on its medium side, it was around 4.30 inches. These compressions are slightly beyond what is needed for edge support to feel like a stable surface. While there were some compressions at the edges during my tests, I never felt that I was at risk of falling out of bed. As a result, I rated the Peace Lily’s edge support at 8.5 out of 10.

      Comparing this to the Emma Comfort mattress, the Peace Lily exhibited firmer edge support by approximately 0.59 inches, and both mattresses achieved the same rating of 8.5 for their edge support performance. The benefit of the Peace Lily’s edge support is its stability, but a potential drawback could be the noticeable compressions at the edges. However, this is not a significant issue for most people, as it still provides a secure sleeping area.
