Frequently Asked Questions 

1. What to look for in a new mattress? 

Without good sleep, you cannot function well and comfort is the key factor to look at before purchasing a mattress. Find the one that fits you the best, and don't try looking for only those that others are selecting. 

Check the size that you need as there are generally 6 to 7 size options that every brand offers. You can measure the size of your bed and get a mattress that will fit. In case you have a customised bed frame, you can purchase a customised mattress online as well. 

Next, make sure the firmness level is perfect as a comfortable mattress is moderately firm so that it can mould around your body better. A very soft mattress will sag beneath your body and may not provide the right level of firmness. 

Excess firmness can also be uncomfortable for your spine and pressure points. However, purchasing a gel-infused memory foam mattress is a good idea since they are comfortable and breathable. 

If you are purchasing online, go through customer reviews to learn more about the best mattress in New Zealand, including the firmness of the memory foam or latex products. Some mattresses even use metal springs inside, but they can sag after some time, which can make the bed noisy and uncomfortable. 

When purchasing a spring mattress, check to see if it’s noisy while the bounciness may make it difficult to get into or out of bed. And look for products with a good warranty so that you can get it replaced in case it does not serve your purpose. 

2. When to change your old mattress? 

If you get a weird smell coming from the mattress, then it is time to change it. Even a quality mattress will stop working after its expiration date, so you will see it sag, and it won’t offer proper support to the spine and back.

Also, most mattresses may deteriorate if you have spilled water on them occasionally over the years. If not properly dried, they can get infested with moulds or the bed might be infested by bugs and you will need to buy a new one. 

Take action immediately after you notice any of these warning signs. 

3. What is the best option for side sleepers? 

People have different sleeping positions, and a mattress with adjustable firmness can help accommodate them all. However, we believe that memory foam mattresses are the best option for side sleepers since memory foam moulds around the body and will adjust according to your sleeping style.

4. What are the best NZ mattresses for hot sleepers? 

Gel memory foam mattresses work the best in keeping the body cool throughout hot nights. The gel top layer is the reason behind this, as it can keep the body’s temperature in check and helps relieve pressure allowing you to sleep better.

Cooling mattresses allow you to sleep comfortably without waking up sweating. Now summer heat or other physical conditions will lead to some sweating because these aren’t magic mattresses.

However, some mattresses come with a built-in cooling technology, which consists of metal particles that are embedded inside. Cooling gel is also used to absorb heat from the body and keep you from overheating while the phase-change technology regulates the body temperature to prevent it from storing heat. 

Then there are cool-to-touch covers that will instantly feel cool as soon as you draw them over you. But these may not be able to retain the cool temperature for a long time as heat from your body will be absorbed soon. 

Next, you can purchase mattresses with plug-in options that use air or water to keep the bed cool. On the flip side, they require a lot of maintenance and some added parts like a cooling unit need to be attached. 

New Zealand has a temperate climate, and you may not need a blanket with cooling technology. But this information may help in purchasing a mattress for a friend who lives elsewhere. That is not all; there are products with innerspring that have more coils than foam. This allows better airflow when compared to other all-foam mattresses. 

5. How to know which New Zealand mattress to choose? 

The best NZ mattress for you is the one that fits your personal preference, body weight, body type, and sleeping position. 

A. Memory Foam 

If you want pain relief, then memory foam mattresses can be the perfect option. They can provide relief to pressure points, and cradle the body for better spine alignment, ensuring less pressure on the hips and shoulders. 

They will also come with motion isolation features so both you and your partner can sleep well. 

B. Innerspring 

Innerspring mattresses work well for those who sleep on their stomach or back as they provide a firmer surface and help in spine alignment. But before making a choice, pay attention to the coil count and the coil gauge to determine how thick the steel coil is. 

Also, look for products with at least 400 coils if you are opting for a queen-sized mattress. There are pocketed coles available as well, where every spring is wrapped for better support. 

C. Latex 

Latex mattresses only use rubber from trees and are completely organic. They are generally more expensive than memory foam options in the mattress industry, but are more durable. You will not feel as if you are sinking because latex mattresses are bouncier than other products. 

D. Hybrid Mattresses 

A hybrid mattress features latex or memory foam along with coils provided at the bottom for added support. The foam layer is present on top and will feel similar to a memory foam bed. However, they are going to be heavier and more expensive than just foam mattresses. 

6. Does body type need to be considered before buying mattresses? 

Yes, the body type will determine which mattress works the best for you. 

A. Lightweight Sleepers 

If you have a small frame, then a softer mattress will work best. That is because you won’t be exerting too much pressure on the surface and will be able to sleep comfortably. But with regard to firmer mattresses, you will not sink in enough and may not get relief from pain in the joints. 

B. Heavy Sleepers 

A firmer mattress is required for those who have a heavy body. Their heavier build means they will exert more pressure on the bed, and may sink in too much on a soft mattress. This may cause issues with spine alignment and lead to back pain, so some brands make special mattresses for people who are above 250 pounds. 

Always consider the weight of the people who are going to sleep on the mattress before purchasing. 

7. How do sleep positions vary?

We will discuss the most common sleep positions and the type of mattresses that fit the purpose. 

A. Stomach Sleepers 

People who like to sleep on their stomachs will need a firm mattress that will not allow the body to sink. The best firm mattresses cradle the pressure points and provide support in the right places to reduce body pain. 

B. Combination Sleeper

Some people do not have a fixed way of sleeping and keep shifting positions. So, it is best to opt for medium-firm mattresses that will allow them to sleep comfortably throughout the night by reducing disturbances. 

C. Back Sleepers

Again medium-firm mattresses work well for back sleepers. Back sleepers can encounter problems with proper alignment if they do not sleep well but these mattresses offer the right amount of support after they lay down. 

8. How to know if the mattress is truly made with organic materials? 

It is best you check the mattress for certifications before purchase as they can be from any of these organisations: 

A. Global Organic Latex Standard (GOLS)

It has strict standards for the manufacturing process and the kind of latex that should be used to make mattresses. 

B. Global Organic Textile Standard ( GOTS) 

This looks at how the fibre has been grown and manufactured, maintaining strict procedures and rules. You can verify if the GOTS tag is legit by checking a public database that is accessible to all. 

9. How long should you leave the mattress to expand before using it? 

If you have purchased a mattress online, then you will have to leave it for a while once you have opened the package. The mattress should be left to rest for around 48 hours to ensure that it expands fully. After that, it will be comfortable and fluffy for sleeping, so do not cover the mattress with sheets before it expands fully. 


Foam mattresses are very common today, and some of the best NZ mattresses are made with premium-quality memory foam. However, keep a watch on the price, as memory foam can be expensive. 

If it goes beyond your budget, you can opt for a mattress with one layer of memory foam and other layers of slightly less expensive materials, supported by springs. 

Also, when the mattress does not come with a cover, remember to buy one. You may drop something on the bed, or your child may spill his/her drink on it, so covering it with a water-resistant material is essential to protect the foam. 

That’s all for today, our top pick is the Emma Comfort, take care and choose wisely.
