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 Vital mattress. Here are some of the features we love: * Excellent value, especially for a hybrid * Perimeter edge support * 7 zones of springs giving the right amount of support to each part of your body * Quick delivery * 100 day trial period and 15 year warranty
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!
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.

Comfort Info

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.
Pincore holes in the memory foam allow for ultra-breathability. Proudly carbon neutral. All carbon produced to create and deliver the Vital Mattress is offset via Green Story.
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.
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
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.
No Disturbance technology means you can have undisturbed sleep, no matter how much you or your sleeping buddy moves in their sleep. The combination of Air Memory Foam with pincore holes and zoned pocket springs allows for air to flow freely throughout all layers of the Vital Mattress, leaving you with a breathable mattress and an ultra-cool night's sleep.
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.
Tranquil Foam is a pressure relieving comfort foam to support you through the night. The Transition Foam alleviates the reactive force of the pocket springs and enhances the no partner disturbance. Pocket Spring with 7 zones of support for each part of the body, supports your spine and cushions pressure points. Recycled Felt is a protective layer for the pocket springs, made from 100% recycled materials. Finally, reinforced firm foam supports and protects the pocket springs.
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.
The Vital Mattress cover is OceanCycle certified, meaning up to 120 plastic bottles were collected from the ocean and repurposed into the cover. This cover may be removed and machine washed. Simply zip the top off and pop it in your washing machine.
