Recommended For
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 Ecosa Mattress is a favorite for sleepers who love firm, cool mattresses. Its gel technology and memory foam core are great for those with back or joint issues, hot sleepers, or partner sleeping. The mattress is medium-firm to extremely firm, depending on the layers.
The Emma Diamond Hybrid mattress with its medium-firm feel is for kiwis who prefer a mattress with superior support, comfort, and cooling.
The Lux Mattress is perfect for those who prefer cool sleeping temperatures, experience back and hip pain, and don’t want to disturb their sleeping partner. Whether you sleep in the middle of the bed or on the edge, the Winkl Lux is comfortable all over.
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 Ecosa Vital Mattress is an excellent hybrid option. The zoned support and airflow make it a comfortable and supportive medium firmness mattress at an attractive price point.
What we like
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
There are several things to love about the Ecosa mattress. Here are some of the features we love: * Triple-layer, adjustable foam * Extreme motion transfer control * Cooling gel memory foam * Cheap and easy to purchase * 100 day trial period
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 Winkl Lux uses activated charcoal and memory foam to ensure maximum comfort and breathability. It is hypoallergenic and created with non-toxic materials. Plus, Winkl offers a 120-night sleep trial and a 15-year warranty.

Keep in Mind
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.
The softest setting on the Ecosa is still quite firm. It’s about the same firmness as a medium on an average mattress. For sleepers who prefer softer beds, an Ecosa mattress might not be ideal. Ecosa’s brand has grown in the past few years, but they still only sell in Canada, Hong Kong, Australia, New Zealand, and the United States. In these countries, shipping is free. If you don’t live in those countries, you can't purchase an Ecosa mattress.
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!
The bed may seem too soft or too firm for some. The Lux Mattress is designed for those who want the perfect mix of softness and firmness. There aren’t any changeable settings on this mattress, so make sure it is comfortable for you before committing to keeping it.
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.
Even though the Vital mattress is only 23cm and the most economic option from Ecosa it is relatively heavy. It comes conveniently delivered vaccum packed in a box but it is difficult to set up if you don't have help. The firmness is a fixed medium feel so it doesn't have the flexibility of adjustment by flipping the internal foam layers like the original Ecosa mattress.

Support Info
N/A
Our high-density support foam is made to provide the best back support. It has ergonomic grooves that serve a two-pronged purpose: to keep the spine aligned, and to allow the mattress to breathe.
Experience the most luxurious sleeping experience with Emma's most premium, pressure relieving, and cooling mattress, made with Diamond Degree® Technology. This 25cm hybrid mattress features layers of flexible foam and individually encased pocket springs, which contour to your body regardless of your sleeping position.
The Winkl Lux's support (base) layer comprises unique support zones designed to maximise spinal alignment and minimise back pain. It's a high quality foam ensuring long term durability and superior support for back, hip and shoulders.
The Ecosa Pure is Ecosa's most luxurious and sustainable mattress that moulds to your body to deliver the sleep of your dreams.

Generous 20cm springs offer perfect spinal alignment with zoned support for your back, shoulders, and knees.
Ecosa's best-selling memory foam combines with 7 zoned pocket springs. The pocket springs are zoned along the body to ensure better alignment and support where you need it, so you can have a pain-free sleep. These pocket springs are individually wrapped coils that move independently to contour to your body, and firmer springs are used along the perimeter of the mattress for reinforced edge support.
Comfort Specs
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.

This high density memory foam is gel-infused so it won't overheat like some memory foams.
The ECO-Tex comes in a medium firmness configuration. It's designed to mould to the body and give it a bounce back. For a slightly firmer feel (medium-firm), flip the layer over to the G-7 gel memory foam. It contains gel-infused particles to help stabilise temperature and keep you cool through the night.
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.
Winkl materials are hypo allergenic & dustmite resistant. Certified free from harmful substances according to leading international standards (CertiPUR-US & OEKO-TEX). Free from chemical fire retardants and free from chemical based glues meaning you and your loved ones will sleep safe.
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.
No Disturbance technology means you can have undisturbed sleep, no matter how much you or your sleeping buddy moves in their sleep.

Support Specs
University research has shown Hygroflex foam to offer superior pressure point relief than other memory foams. It also allows you move freely and not have that 'stuck in' feeling you may have had with other foams. The high density foam support core provides comfortable support and durability, while minimising partner disturbance and roll together.
Our high-density support foam has ergonomic grooves that does not only provide extra breathability, but also paves way for zero-partner disturbance and long-lasting durability.
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.
A supportive base foam layer offers durability and support for all sleepers. Backed by a 15-year warranty - that's just 33c a night to sleep on a queen. The other key added feature is the precision cut spinal support zones, these zones allow your hips and shoulders to sink in which improves spinal alignment.
Micro coils provide precision support and contouring for pain-free sleeping. Adaptive Talalay Latex for a medium-firm feel and dynamic support. Sleep supported with 7 zones of pocket springs ensuring perfect spinal alignment. Firm pressure supports your lower back and knees, with cushioning for the pressure points in your hips and shoulders.
