3 Best-Rated Mattresses in a Box in New Zealand in 2024 (January 2024)

Best Overall — Editor’s Choice The Emma Comfort Mattress

Emma Comfort Mattress


  • It features a perfect blend of zoned support and cushioning for optimal pain relief.
  • The mattress cover’s breathability and foam construct are adept at temperature regulation.
  • The mattress has zero motion transference, a feature especially great for partnered sleepers.

The Emma Comfort mattress is one of the best memory foam mattresses in a box in New Zealand. Although memory foam mattresses are associated with heat retention and low bounce, the Emma Comfort mattress offers premium comfort without any of the popular drawbacks. Safe to say, it’s a luxury mattress designed for maximum relaxation and enhancing restorative sleep.

The mattress offers a medium-firm firmness level that has been found to work well for various sleeping styles. It fuses a dense core that offers spinal alignment with an Airgocell foam comfort layer for sinkage. This healthy blend creates a mattress surface soft enough to sink in without feeling restrictive and sturdy enough to provide lumbar support.

From my review, the Emma Comfort had 0.19 inches more sinkage than the Peace Lily on its medium side. That means the Emma has more of a body-hugging cradle that can offer more profound pressure relief.

In addition, the Emma Comfort mattress is excellent for partnered sleepers as it provides superior motion isolation features that guarantee zero bounce. From my glass shaking tests, the Emma Comfort had 4.5 inches better isolation than the Peace Lily mattress. That means the Emma Comfort has a higher level of which to keep your sleep undisturbed from a restless partner. Another feature partnered or hot sleepers will enjoy is its thermoregulation; it is effective at heat dissipation and wicking away moisture during sleep, leaving the user cool and refreshed all night long.

Based on Our Review

I tested the Emma Comfort mattress with my partner to see how effective it was at motion isolation. Its memory foam build has a slow-moving feel that restricted all movements to my side of the bed while my partner slept undisturbed, and this was despite me tossing extra-hard all through the night.

Best Option for Side Sleepers Peacelily Mattress

Peacelily Mattress


  • Most resilient material with natural rubber latex allows for proper body pressure distribution;
  • This double-sided mattress lets sleepers choose between firm and medium levels. It allows utmost comfort and preserves body structure 
  • The hardened handles make flipping the mattress a one-person task.

The Peacelily mattress is another mattress model that ranks as one of the best mattresses in a box in New Zealand. Its all-latex construction is ideal for side sleepers as it offers sufficient sinkage to cushion your hips, shoulders, and lumbar region while simultaneously providing back support and spinal alignment, ensuring you don’t sink too much.

Based on my tests, the Peace Lily had 0.04 inches less sinkage than the Koala making both mattresses incredibly similar regarding compressions. This means the Peace Lily is a good memory foam alternative for deep pressure relief and a moderate body hug.

The Peace Lily’s response and buoyancy are also worth looking at. Based on my review, the Peace Lily’s firm side had 2.36 inches more bounce than the Koala mattress. That makes the Peace Lily more responsive to pressure, and I found it easier to move across the bed’s width.

Furthermore, this material is super hygienic, which is crucial for any mattress (1). On average, we spend a third of our lives sleeping; hence we should consider this aspect often. Plus, the Peacelily Mattress is handmade and comes with a generous 25-year manufacturing defects warranty. That fact alone is a confirmation of the quality of this product.

However, New Zealand’s weather might not be too ideal for rubber latex. Because of this, products such as this may require frequent maintenance. So, to prevent your mattress from cracking after a few years, stay mindful of its condition.

Based on Our Review

My favorite feature from reviewing the Peacelily mattress was its reinforced edge support. This feature allowed me to sleep and sit on the mattress's edge without fear of falling or sagging. In addition, it made getting out of bed easier.

  • The mattress is optimized for breathability and combats body heat with its graphite-infused cover.
  • It has a zoned support system that delivers lumbar support for spinal alignment via varied firmness.
  • Its innerspring layer has paths that negate heat retention to ensure cool sleep.

Even though coming at the end of our list, the Emma Diamond Hybrid is an excellent mattress that would work well for hot sleepers. The mattress has a proprietary Diamond Degree technology that generates graphites to ensure you stay cool all through the night. Coupling this with the heat dispersion capacities of pocket springs, night sweats become a thing of the past.

In addition, the mattress is quite adept at stress relief with its combination of spring coils and a high-resistance base foam that generates pushback for staying afloat, while the cushioning comfort and transition layers provide cradling and muscle massaging.

Based on Our Review

Apart from being extra cooling, I particularly enjoyed how cradling the Emma Diamond Hybrid was. While testing the mattress, I had prepared for some firmness because of its spring coils; however, I was pleasantly surprised by how intense the hug was. It made me feel like I was sleeping on a cloud; excellent for tension relief.

Why You Should Trust Me

To find the best mattresses in New Zealand, I reviewed a large number of them first. I have certain methods for testing mattresses and assessing them. For example, the firmness level, warranty, trial, construction, and other factors can say a lot about mattress quality. I narrowed the options down to the three mentioned in this article and wrote down my first-hand experiences for you to have an easier decision-making process.

Buyer’s Guide to the Best Mattress in a Box in New Zealand in 2024

Since recently, a quality mattress is no longer considered a luxury. Thanks to the online competition, they are more affordable than ever. As a result, you do not have to spend the equivalent of a car price to get a decent bed. Plus, this development is more than welcome for anyone valuing their sleep hygiene. Investing in products like a mattress in a box is a shortcut to better well-being. However, not all items offer the same benefits. No matter how similar they might look in the photos, they’ll differ on some key aspects. Therefore, given how crucial the switch to a mattress in a box can be, one should learn some “know-how”. At the very least, keep an eye on essentials such as the ones listed below.

Mattress Resilience

Mattress resilience refers to the sweet spot between firmness and softness. Sleepers should look for mattresses that support their pressure points without deep sinking. If it’s possible to sacrifice everything else to get adequate mattress resilience, it’d still be a good buy. It’s because the wrong configuration may cause long-term complications to the human anatomy. So, this is the primary focal point you should be concerned with. All the more so if your purchase is for some younger member of your family. For them, you should be extra careful and do proper research, A mattress that will support their still-developing bodies is a must. Otherwise, unwanted conditions may appear much sooner than expected. 


The average warranty duration in the New Zealand mattress market is ten years. Hence, you shouldn’t settle for anything less. According to science, people should replace the mattress every six-eight years. Still, some mattress companies, like Peacelily, offer a 25-year warranty. So, consider this longevity before deciding on a mattress. For starters, determine whether you’re looking for short or long-term investment. Next, consider what each company offers, and don’t hesitate to go more in-depth with your inquiry. Finally, collect as much data as possible before placing your trust in one particular company.


Customers should be vigilant about any odor surrounding their new mattress in a box. Specifically, if there is any stronger scent present, that would be a huge no. If that is indeed the case, then it might be an indicator of harmful chemicals. But, the human nose gets used to smells after a while. Hence, you shouldn’t rely on your senses too much. Also, if the smell persists for too long, you should take action promptly. In short, never hesitate to report such things to the seller. It is an immediate red flag that you shouldn’t disregard under any circumstances.

I ensure my bedroom is well-ventilated before opening my mattress package as this allows the off-gassing scent to disappear quicker during expansion.

Airing your mattress at least once in 3 months can benefit the mattress’s lifespan. I do this studiously as the practice ensures any moisture buildup and allergy-causing irritants in my mattress gets evaporated.


A buyer shouldn’t dismiss a mattress if it isn’t instantly comfortable. Instead, sleepers should consider covers, toppers, and additional beddings. Such upgrades can make all the difference, and often come cheap, too. Plus, you can mix and match them to your preferences. Later, you can even go for new ones, just to spice things up a bit. For example, Peacelily offers the Plush Topper, which can change a lot about the mattress. Hence, some of those upgrades are even essential for properly utilizing your mattress in a box.

Trial Period

Most mattress-in-a-box companies offer a trial period for sleepers to test their products. It makes sense because judging a mattress takes more than a few nights of sleep. Buyers will probably try at least a few before settling for one. After all, mattresses are there to stay. So, if a brand is too stingy when it comes to the free trial, take heed. It might mean there are bad surprises in store for the customers. Alas, you won’t find those in this listing of the best mattresses in a box in New Zealand. All of the five items featured here are deserving of your attention. That means they’ve earned their trustworthy status the hard way.

Payment Options

Buyers should also think about installment payments. While mattresses in a box are heaps cheaper than how they used to be, it still is quite the investment. So, you should ask for convenience when it comes to your purchase. Next, consider those brands that support a myriad of options in this regard. For example, Ecosa offers installments through ZipPay and Humm. These payment methods are risk-free, require no credit check, and are more manageable than most. In that way, the brand manifests its care for the consumers, by valuing their time, also.


Buyers must measure their bed frame to choose a fitting mattress size. Then, it is crucial that the bed frame and mattress are a perfect fit. Otherwise, the mattress will sag, bulge, and sink. Thankfully, companies offer dozens of sizes to choose from for this exact reason. So, it falls on the buyer to take precise measurements before going to the store or ordering online. Therefore, it’s better to spend more time measuring, than having to return the mattress later on.

Mattresses in a Box Shopping: Dos and Don’Ts

  • Do look for discounts: Sometimes, companies drop their prices or offer special discounts. This is an awesome opportunity to take advantage of. So, make sure to scour the net and find notifications in time. It's also wise to look for third-party companies that bring budget-friendly prices to consumers. That way, you’ll always stay in the loop.
  • Don't invest in a cheap mattress in a box: Though a higher price is no guarantee for quality, a low one isn’t either. In practice, they can be both misleading at the end of the day. Hence, consider the other factors as well. Every product rounds up more than one aspect, and you should take them all into account. Only afterward should you think about clicking that "buy now" button.
  • Do consider your weight: Mattress buyers should know how their weight comes into play. It'll help them decide on the suitable firmness level of a mattress. The heavier the sleeper's weight, the heftier the fabric should be. 
You might want to invest in a bed frame to increase your mattress’s weight limit and support. I’ve found that solid foundations are great for hardening mattresses while slatted foundations are adept at bounce and breathability.
  • Don't dismiss mattresses in a box: The demand for products like these is on the rise in the past several years. As a result, the technology to put a bed in a box also came a long way. Many brands gained popularity the hard way, and they keep up that level of dedication. So, if one company sounds familiar to you, there’s probably a good reason for it.
  • Do look for online reviews: Like when it comes to many other items, buyers can access tons of reviews online for free. So, they should read and ask questions about the mattress quality, price, and benefits. For this, there are a plethora of review and forum sites. With a little diligence, you can find honest and in-depth reviews fast.
  • Don't throw away the old mattress: Companies will arrange to donate the buyer's old mattress to local charities. So, buyers should ask about this free service. In that way, they can get rid of the old mattress while helping the local community.

    1. You’re welcome! That’s awesome to hear. Enjoy your perfect mattress and the great night’s sleep it brings!

  2. I’ve heard about memory foam and innerspring mattresses. Can you explain which one is better for side sleepers in simple terms?

    1. For side sleepers, memory foam is often the better choice. It contours to your body, relieving pressure points. Innerspring mattresses may not provide as much cushioning for side sleeping.

    1. One excellent option to consider is the Peacelily mattress.

Your insights would be greatly appreciated in helping me make a more informed decision.

    1. Selecting the right mattress firmness is undoubtedly a significant decision, one that can greatly impact your quality of sleep. The ideal firmness level often varies based on personal preference, but there are some key criteria to consider. To help you navigate this choice, I’ve outlined a few important factors. It’s important to take into account your sleep position – side sleepers generally prefer a softer mattress, while back and stomach sleepers tend to opt for firmer options. Body weight plays a role as well; lighter individuals may find a softer mattress more comfortable, while heavier individuals may benefit from a firmer surface. Additionally, consider any specific health concerns or back issues when making your choice. You can find more detailed information on how to determine the right firmness level in our comprehensive article on mattress firmness, which you can read here

      In summary, the best approach is to assess your own comfort and support needs, taking into account your sleep position, body weight, and any physical concerns.

    1. I’d recommend the Emma Comfort Mattress, which showcases excellent motion isolation properties. This mattress is particularly crucial for light sleepers who cherish undisturbed rest, even if they share their bed with restless partners.

      The Emma Comfort mattress has proven to be effective in minimizing motion transfer, offering a more tranquil sleep experience. It absorbs minor movements exceptionally well, although you might still be aware of more substantial motions, such as getting out of bed. Nonetheless, the mattress’s performance in this regard is commendable.
