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 Emma Original mattress is a medium-firm foam model that’s ideal for side sleepers and people with partners. It’s also great for people who like the pressure relief of foam mattresses but want to keep cool.
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 Winkl mattress is an excellent fit for anyone looking for a memory foam model with enough support and comfort to relieve pressure on joints. The Winkl-flex comfort foam is designed to provide pressure relief on your back, hips, and shoulders while sleeping, while a base foam provides additional support and durability. The gel memory foam also keeps the mattress cool, making it the right choice for those who are often too warm at night.
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 Emma Original mattress is a popular choice in New Zealand, known for its unique features and benefits. This mattress offers a comfortable and supportive sleeping surface that is suitable for all types of sleepers. Here are some of the USPs of the Emma Original mattress: Pressure-relieving foam: The Emma Original mattress features a top layer of memory foam that is designed to relieve pressure points and provide excellent support for your body. This layer contours to your body's shape and reduces the strain on your joints and muscles, helping to alleviate back pain and other sleep-related issues. Breathable materials: The Emma Original mattress is made with breathable materials that help regulate your body temperature and prevent overheating during the night. This feature is particularly beneficial for those who tend to sleep hot and wake up sweaty. High-quality construction: The Emma Original mattress is made with high-quality materials that are durable and long-lasting. It is also designed to resist sagging and maintain its shape over time, ensuring a consistent level of support and comfort. Easy delivery and setup: The Emma Original mattress is delivered straight to your doorstep in a compact box, making it easy to move and set up. The mattress can be easily unpacked and set up in minutes, without the need for any additional tools or equipment. Sleep trial and warranty: The Emma Original mattress comes with a generous 100-night sleep trial, allowing you to test the mattress in the comfort of your own home. It also comes with a 10-year warranty, providing peace of mind and ensuring that you can enjoy your mattress for years to come. Overall, the Emma Original mattress is a great option for those looking for a comfortable, supportive, and high-quality mattress at an affordable price point. Its pressure-relieving foam, breathable materials, and easy delivery and setup make it a popular choice for New Zealanders.
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.
The Winkl Mattress has three foam layers to optimize the amount of bounce and softness while you sleep. This mattress has a “one-firmness-fits-most” model, so many sleepers find the medium-firmness a perfect balance. Winkl also offers exceptional and accessible customer service, making the experience of buying from them easy and stress-free. And with every purchase going towards protecting wildlife conservation efforts, you can feel good about where you’re spending your money.
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!
There are a few negative features to consider before making a purchase. These include: Edge support: The Emma Original mattress does not have reinforced edges, which may cause the mattress to compress when sitting or sleeping near the edge. This may be a concern for those who need extra support near the edge of the bed. Off-gassing: Like most foam mattresses, the Emma Original mattress may emit a slight odour when first unpacked. While this odour should dissipate within a few hours, some customers may find it unpleasant.
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.
While the “one-firmness-fits-most” design may optimize the level of comfort for many sleepers, it can also create challenges if your mattress preferences fall outside of the balance. If you prefer especially hard or soft mattresses, this may not be the best choice for you.
