The Ecosa Pure Mattress is the most luxurious offering to date from Ecosa. The certifications will be well received by eco-conscious shoppers (Carbon Neutral, OEKO-TEX, OceanCycle). The adjustable firmness makes it a winner for those already familiar with the original Ecosa mattress and whom may be considering an upgrade.
The Emma Diamond Hybrid mattress with its medium-firm feel is for kiwis who prefer a mattress with superior support, comfort, and cooling.
The Napp mattress has a medium firmness best suited for side sleepers and couples who find it challenging to agree on a mattress's firmness.
The Peace Lily Hybrid Mattress is recommended for individuals seeking a cool, comfortable, and supportive sleep surface. It is ideal for those who prefer natural and organic materials, as it features natural latex, organic cotton, and pocket springs. Additionally, it's suitable for allergy sufferers due to its antimicrobial and dust mite-resistant properties. The mattress is also an excellent choice for eco-conscious consumers, as it is crafted from sustainable and biodegradable materials.
What we like
There are several things to love about the Ecosa Pure mattress. Here are some of the features we love: * Carbon neutral * 80 recycled bottles used in the cover * Latex foam, 20cm springs AND micro coils * Adjustable firmness * 100 day trial period and 15 year warranty
The Emma Diamond Hybrid mattress is a top-of-the-line product that provides unparalleled comfort and support. As someone who has had the opportunity to test this mattress in the comfort of my home in Dunedin, I can confidently say that it is one of the best mattresses I have ever slept on. One of the standout features of the Emma Diamond Hybrid is its ability to conform to the body's natural curves, providing a supportive and comfortable sleeping experience. The mattress uses advanced zoning technology to distribute weight evenly across the surface, reducing pressure points and allowing for a more restful night's sleep. In addition to its supportive design, the Emma Diamond Hybrid also features a plush pillow-top layer that adds an extra layer of comfort to the sleeping surface. The soft yet durable cover material also contributes to the luxurious feel of the mattress. Another great feature of this mattress is its ability to regulate temperature. The combination of memory foam and pocket springs allows for optimal air circulation, preventing overheating and ensuring a comfortable sleep throughout the night. Overall, I would highly recommend the Emma Diamond Hybrid mattress to anyone looking for a comfortable and supportive sleep surface. Its innovative design, plush pillow-top layer, and temperature regulation features make it an excellent investment for anyone looking to improve their sleep quality.
The mattress is medium-firm and balances the need for a sturdy, firm, yet breathable mattress. The cover is also removable and comes from a material that excellently controls temperature. o
This hybrid mattress, made from natural latex, organic cotton, and individually pocketed springs, ensures a cool and comfortable sleep with exceptional airflow and breathability. The natural latex provides antimicrobial and dust mite-resistant properties, while the organic cotton cover minimizes allergens, making it ideal for those with allergies. Designed for sustainability, the hybrid mattress use durable, biodegradable materials that support carbon sequestration, reduce carbon emissions, and protect ecosystems. With Peace Lily, you can enjoy a restful night's sleep while making a positive impact on the planet.
Keep in Mind
The Ecosa Pure is only available in Queen and larger sizes. This means if you have a smaller bedroom with only space for a double then this mattress is currently unavailable in that size. The 29cm depth and the luxurious materials used in the construction make this extremely heavy to maneuver.
The Emma Diamond Hybrid has the highest RRP of any of the mattresses listed on this NZ site. So don't forget to click our links and apply our discount code at checkout to save!
When you unpack the Napp mattress for the first time, it emits some off-gas smells that result from the manufacturing process, much like any other all-foam mattress. People who are allergic to off-gas compounds may struggle with this for one or two nights. Its edges also lack reinforcement, so weightier customers might choose to sleep in the centre instead of the edges of the mattress.
When using the Peace Lily Hybrid Mattress, keep in mind: 1. Firmness Adjustment: The mattress itself does not have a flippable firmness option but can be adjusted with a Peace Lily Mattress Topper. 2. Support and Comfort: Made with natural latex, organic cotton, and pocket springs for optimal support, breathability, and temperature regulation. 3. Allergy-Friendly: Features antimicrobial properties and minimizes allergens. 4. Sustainability: Constructed from biodegradable, eco-friendly materials. 5. Care and Use: Requires a proper bed base to ensure longevity and performance.

Firmness Info
The Pure Mattress has two interchangeable layers that you can choose from depending on your sleeping style and overall preference for firmness. The mattress will arrive with the medium firmness setting, but easily switch between medium and medium-firm for customisable comfort. Simply unzip the cover, and swap the 1st and 3rd layer of the mattress, keeping the micro coils layer inbetween.
The Emma Diamond Hybrid has a medium-firm feel. It is slightly plusher (less firm) than the Emma Comfort.
The mattress has a base layer that supports the natural curvature of your body - not too firm, not too soft.
This mattress is tailored for the diverse heights of New Zealanders, featuring a softer feel for the head and feet and firmer support for the hips and torso. Extensive research has been done to eliminate the typical springy feel found in hybrids, enhancing both safety and durability. The Peace Lily Hybrid minimizes motion transfer, offers superior support, relieves back pain, and ensures even weight distribution for sustained comfort. While the hybrid mattress doesn't offer flippable firmness options, you can adjust its firmness with a Peace Lily Mattress Topper, which many customers add for extra luxury.

Comfort Specs
No Disturbance technology means you can have undisturbed sleep, no matter how much you or your sleeping buddy moves in their sleep. BounceTech™ Latex Foam is an open cell Dunlop Latex which is used for its breathable comfort and medium firmness. Micro Coil Technology allows airflow through the up to 2,000 individual 2.5cm coils.
Diamond Degree® foam is infused with diamond and graphite particles. This innovative coating quickly dissipates excess heat away, thereby extending the duration of your deep sleep phase. The foam's low rolling-resistance also helps minimize feelings of movement so you sleep undisturbed. Individually encased pocket springs offer superior breathability over a standard foam mattress by allowing air to flow more freely.
A Hygroflex comfort layer, exclusive to Napp, has superior temperature control than regular memory foam. A mid layer of Gel Infused Memory Foam moulds to your curves. It's pressure-relieving properties help to increase blood circulation, which reduces tossing and turning that can disrupt your sleep. This high density memory foam is gel-infused so it won't overheat like some memory foams.

Finally, reinforced latex foam supports the pocket springs.
Adaptive comfort foam is ergonomically designed and adapts to your body and optimally distributes body pressure for a more comfortable sleep regardless of your build and sleeping position. The individually encased steel pocket springs provide dynamic body adaptation. The HRX supportive base foam layer is extremely durable and has incisions that allow the mattress to adapt well to your body by providing better support for your pelvis, shoulders, and neck.
