Recommended For
The Emma Diamond Hybrid mattress with its medium-firm feel is for kiwis who prefer a mattress with superior support, comfort, and cooling.
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.
What we like
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.
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
Keep in Mind
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 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.

Comfort Info
Each Emma mattress is a result of an extensive development phase conducted by Emma's team of sleep experts and researchers. Leveraging top German engineering and expertise in neuroscience to give you the best sleep you've ever had. Sleep faster, deeper, and longer with the revolutionary Diamond Degree® foam infused with graphite particles that helps regulate your body temperature.
The ECO-Tex, an open-cell foam, is the newest comfort layer. This is engineered to be more breathable and durable than our previous latex foam. The Ecosa G-7 Gel Memory Foam is designed to evenly distribute pressure points and prevent the body from sinking too deeply.
Support Info
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.
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.
Comfort Specs
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.
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.
Support Specs
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.
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.
Fabric Specs
A fully breathable and washable premium cover. Designed to help facilitate heat dissipation of the Diamond Degree graphite foam. In-built handles allow for easy handling. The top cover is made from 99% polyester and 1% elastane, the side cover is 100% polyester, and the bottom cover is 87% polyester and 13% polypropylene.
We use the highest quality premium polyester in our removable soft-touch cover. This is breathable, flexible, and machine-washable.
