The Science of Sleep: How Materials Impact Sleep Quality

Tuesday, July 8th, 2025

The mattress materials you choose can have a huge impact on your quality of sleep, affecting temperature, comfort, support, and circadian rhythms. The experts at Dreamwool Beds are here to talk sleep science and how to choose mattress materials that will help you get the best night’s rest.

The Role of Sleep Science

The truth is that sleep science can be as much (or more) of a hindrance as it is a help. The gadgetization of sleep, by adding lots of technological features and devices, is over complicating our sleeping environment. We often cause ourselves more anxiety and apprehension, leading to poorer sleep outcomes. When choosing mattress materials, all-natural is always best, and when considering sleep hygiene, our best recommendation is to declutter your space, put the trackers away, and just get a great night’s rest.

Breathability

One of the most important factors in sleep comfort is the breathability of your mattress. Chemically made synthetic mattress materials, such as memory foam, don’t allow air to pass through. Some modern bed manufacturers are trying to resolve this problem by adding a top layer of gel to absorb excess heat and maintain a stable temperature. But, however you dress them up, these materials still can’t breathe.

This means that they are actually making mattresses hotter, not cooler, even if they might claim to offer temperature control or feel cool to the touch when you first see them in a shop. Sleep on one for a couple of hours, and you’ll quickly feel those gels warm up and soften, trapping heat, losing support, and leaving you with an inferior quality of sleep.

Your Sleep Cycle

Our natural circadian rhythms are intended to help our bodies relax and get restful sleep. If you are sleeping on a hot mattress made with synthetic materials that aren’t breathable, you’re more likely to feel anxious as you struggle to achieve and maintain a good quality of rest. Your heart rate will increase as your body temperature rises, resulting in a disrupted sleep cycle.

Conversely, the breathability of natural mattress materials, such as those used by Dreamwool, helps to control your bed’s microclimate and achieve temperature neutrality. This allows you to better weather external temperature changes or hormonal fluctuations and achieve an undisturbed sleep cycle. By stabilising the temperature of your sleep environment with all-natural materials like Merino wool, your body doesn’t have to adjust to changing temperatures through the night. Your heart rate can remain consistent, allowing you to achieve a deeper, more restful sleep with fewer disruptions.

Natural is Best for Temperature, Comfort and Health

When it comes to sleep science, if a mattress has lots of add-on features, you should be asking why they’re needed. In many cases, the cooling mechanisms you see in high-tech mattresses are addressing problems created by flaws in the original mattress design. While you may be able to briefly cool down an inferior mattress, if air can’t move freely through it – which is impossible in a closed-cell synthetic foam – you’ll never really be able to keep cool. This is because synthetic foams and gels don’t maintain their support overnight, eventually trapping air flow and preventing breathability. As the night wears on, you’re likely to feel the bed get hotter and more uncomfortable.

Don’t be taken in by buzzwords or new technologies that tick boxes but don’t deliver on their promises. Great sleep is simple. And the healthiest, most comfortable mattress will always be one that is made with high-quality, all-natural materials in meaningful volumes.

There is nothing better or more luxurious than a mattress made with the simple goodness of natural Merino wool.

Why Merino Wool Outperforms Every Other Mattress Material

Tuesday, July 8th, 2025

Merino wool is a natural, lightweight fibre renowned for its exceptional softness and breathability. At Dreamwool Beds, we know that Merino is the best mattress material because it far outperforms synthetic (and nearly all natural) alternatives.

Here, we break down some of the key benefits you can expect from a Merino wool mattress and why you should choose one when purchasing your next bed.

How is Merino wool sourced, and why does it perform so well?

Dreamwool’s Merino wool is responsibly sourced directly from select high-country farms in New Zealand’s South Island. Merino sheep thrive in the high country due to their natural ability to withstand a huge range of temperatures and climate conditions. This makes their wool uniquely suited for bedding due to its superior temperature regulation and moisture control, keeping you comfortable all night and in any season.

Key Benefits

Breathability

Merino wool excels in terms of breathability. This means that it offers many thermophysiological benefits, including superior moisture control and temperature regulation, as well as antimicrobial properties that make it uniquely suited for a fresh, dry sleeping experience.

Marrying Softness with Durability

Merino wool is supremely soft and luxurious due to its natural elasticity and high fibre density, both of which also make it especially strong and durable. It is naturally stain-resistant and long-lasting, making it an excellent choice for longevity and resilience.

Comparing Merino Wool with Other Materials

When choosing between Merino and synthetic mattress materials, the truth is that there is no comparison. Chemically made synthetic materials like memory foams, gels, and glues trap heat, causing discomfort, night sweats, and interrupted sleep, whereas lush, breathable, all-natural Merino provides unparalleled microclimate control for a truly restful sleep.

But how does Merino stack up against other natural mattress materials?

Wool vs Cotton

Cotton (particularly organic cotton) can be a versatile and sustainable natural material, but it doesn’t have the same ability as wool to absorb and disperse moisture. Merino offers superior moisture-wicking benefits, and it is more durable over time than cotton.

Merino vs Other Wools

The fibres of the Merino sheep grow longer, with greater density than traditional wool. They don’t stick to each other and felt down, which means that they don’t compact as much or as quickly as other types of wool. This translates into a mattress with exceptional softness and comfort, greater longevity, and a longer period of optimal support.

Quality AND Quantity

It’s important to remember that it’s not just the quality of your mattress materials that counts. For Merino wool to perform its best, you also want to look for a high volume of material, such as you will find in Dreamwool’s generous, natural comfort layers. For instance, our Queen Size luxury mattresses contain more than 9.5kg of all-natural, locally sourced Merino – that’s more than 10% of their overall weight.

Why You Should Choose Merino

Temperature neutrality is the key to sleeping soundly in all seasons; this is where Merino wool really thrives. The ability of Merino sheep to weather huge fluctuations in temperature and moisture translates into a mattress that will keep you sleeping soundly all year round. By using thick, plush layers of Merino, Dreamwool mattresses effortlessly maintain your ideal temperature and draw humidity away quickly, ensuring a dry, breathable sleep environment throughout the night.

Here at Dreamwool, we know that this exceptional material is second-to-none for comfort, support and breathability, and we’d love to show you how an investment in a luxury Merino mattress can boost your wellbeing and help you rest easier tonight.

How to Choose the Right Mattress for Your Sleep Style

Tuesday, July 8th, 2025

Every sleeper is different, and there are a lot of factors that can determine what mattress will be best for you: age, body shape, weight, sleep preferences, sleep position, injury, illness, partner comfort, and more. So, how do you choose the right mattress for your sleep style?

The expert team at Dreamwool Beds has put together this handy mattress comfort guide to help every sleeper know where to start when selecting their next mattress.

The Right Materials

Your first priority when choosing your next bed should be to find one that is filled with high-quality, natural materials at meaningful volumes. Synthetics like memory foams can trap heat, leading to night sweats and sleep disturbance. For maximum breathability, look for materials like natural latex and Merino wool.

Then, you should consider whether you would prefer a pocketspring or a latex mattress; these options offer two different but equally luxurious sleep experiences. Pocketsprings provide a flatter style of firmness, with latex offering a bit more contour and deflection.

What firmness should I choose?

There really is no such thing as an ideal firmness or a one-size-fits-all solution; the only way to know for sure what you need is to lie down on the mattress and try it for yourself. We recommend spending at least a few minutes trying it on both your back and your sides. If you’re tossing up between two options, go with slightly softer; a bed will always feel firmer after eight hours of rest than it did after a 10-minute test on the shop floor.

As you’re weighing up which firmness could be right for you, here are a few factors to consider:

Age

Most of us will find that our sleep preferences change with age, often leaning towards a softer mattress as we get older.

Injury

Injuries and chronic pain can affect your choice of firmness, particularly if you have sensitive joints, which may require a softer level of support, or lower back injuries, which may benefit from additional firmness.

Partner Comfort

Your partner’s comfort may also dictate your firmness selection. Softer mattresses can absorb more movement, reducing partner disturbance.

Weight and Body Shape

Smaller and lighter people often prefer a softer mattress, while larger and heavier people may need firmer support. Similarly, a curvier person with a pear-shaped body might be more comfortable with a slightly softer mattress than a person of the same weight and size who has a more rectangular shape.

Sleep Style

All of these factors, combined with your sleep style, can help you select the best mattress for your needs. Your preferred sleeping position can play a big role in what firmness of mattress is best for you. Back sleepers may benefit from slightly firmer support, while side sleepers often prefer a softer, more contouring mattress.

Let’s look at a few different types of sleepers to see how their selections might compare.

50kg Side Sleeper

Often, the best mattress for side sleepers is one that is slightly softer. This is also true for someone whose body shape is smaller and less curvy, as the softer surface will contour around them for optimum support.

50kg Back Sleeper

Back sleeping typically requires a little extra support, though you’d still want to be mindful of this sleeper’s weight and body shape. They could be well-suited for either a soft or a medium firmness.

120kg Side Sleeper

It’s worth considering this sleeper’s body shape, as a side-sleeper with bigger shoulders might prefer a softer surface that allows them to deflect into the mattress. If they carry more of their weight in their mid-section, a firmer mattress with extra support would be appropriate.

120kg Back Sleeper

This person would probably be best suited to a firmer mattress with extra support, but again, it’s also worth taking into account factors such as body shape, age and injury.

Don’t Compromise on Sleep

The best investment you can make in tomorrow; is a good night’s sleep. To find the best latex, pocketspring or adjustable mattress for you and your individual sleep style, do your homework, look for all-natural materials, talk to your salesperson, and ask to see samples of what’s inside.

For partners with different sizes, shapes, and sleep preferences, we’d highly recommend a Twin Super King, which gives each sleeper a full single mattress to themselves, tailored to their own sleep style and comfort preferences, without the need for compromise.

What is the best position for a bed in Feng Shui?

Thursday, May 1st, 2025

Feng Shui is a system of Chinese principles that governs spatial arrangement with regard to the flow of energy, or chi. The core idea behind Feng Shui is that you can experience favourable or unfavourable energy effects, depending on how you design and arrange spaces. By balancing the world’s five main natural elements – wood, fire, earth, metal and water- it’s said that you can increase your quality of life and create harmony in your home. 

When deciding the best position for your Dreamwool Bed in Feng Shui, there are a few key things to consider.

The Commanding Position

Feng Shui dictates that you should place your bed in what’s called the “commanding” position, where you can easily see your bedroom door while in bed without directly facing it (doing so, with your feet pointing towards the door, is known in Feng Shui as the “coffin” position).

Ideally, your bed should be placed diagonally to the door. If this is not feasible, you can still achieve a commanding position by placing a mirror in your bedroom so that you can see the reflection of the door while in bed.

Face South

A south-facing bed is believed to encourage wealth. If you can face south while in the commanding position and avoiding the line of doors, this is generally the best Feng Shui position to increase your overall quality of life. A good second choice would be to face east, as this is thought to improve health and focus.

Ground Your Bed Against a Solid Wall

It is important in Feng Shui to have a solid wall behind your headboard. Place the head of your bed against a solid wall, avoiding windows.

If you have an en suite bathroom, you should also avoid placing your headboard on the same wall where the bathroom is located. 

Avoid Architectural Features and Clutter

Where possible, do not place your bed directly under architectural features, beams, or sloped ceilings, as these are thought to create oppressive energy above you. If this is unavoidable, you could choose to mask architectural ceiling elements with paint or fabric. It is also recommended to avoid clutter in your bedroom space, as this can interrupt the flow of energy.

Provide Access to Both Sides of Your Bed

To keep the energy – chi – flowing smoothly around your bedroom, ensure that you have at least 45cm of space around both sides of the bed. Pushing your bed up against a wall on one side is thought to hinder the balance of yin and yang energies, as well as being impractical for partners who may wish to access both sides of the bed.

Where Needed, Use Crystals and Mirrors

Mirrors and crystals can both be valuable tools in achieving good Feng Shui. Place mirrors perpendicularly to doors to make your bedroom seem more airy and spacious, and use hanging crystals between your bed and the door to disperse any negative energies.

Find the Best Placement for You

Many of the tips provided by Feng Shui are also great from a practical standpoint: a solid wall behind your headboard provides you with greater temperature consistency, reduced clutter helps to create a greater sense of calm, balanced space on both sides of the bed provides clear access and equal partner comfort, and avoiding a shared wall with the toilet will prevent sleep disturbances in the night.

Feng Shui principles can be a great place to start as you consider your bedroom design decisions, but it’s always best to find the right solution for your needs and space. Ultimately, the experts at Dreamwool recommend that you prioritise quality sleep over all else, and design the space you need to make that possible.

What Does an Orthopedic Bed Do?

Thursday, May 1st, 2025

What is an orthopedic bed?

Many mattress manufacturers include what they refer to as “orthopedic” beds in their product range, stating that these beds are created specifically for good spinal alignment. But the truth is that there really is no such thing.

What are often referred to as orthopedic beds are simply firmer mattresses that can be beneficial for people who, perhaps, have had an operation and require a specific level of support.

What are the benefits?

The claim is that the benefits of an orthopedic bed include better support, higher quality materials, pain and pressure relief, and temperature regulation. But, generally, orthopedic is just a description given to firmer mattresses within a manufacturer’s existing product range.

The good news is that every Dreamwool mattress offers all of these benefits and more. With each Dreamwool bed handmade to order and filled with only the finest natural materials, we are able to outperform so-called orthopedic mattresses with every bed we produce, and we can tailor each one to our customers’ unique needs and preferences.

What is the difference between a regular bed and an orthopedic bed?

The bottom line is that there isn’t one (or, at least, there shouldn’t be). When bed manufacturers are talking about orthopedic beds, typically what they mean is a firmer mattress with extra support and less comfort layers. 

With Dreamwool beds, any mattress selection you make will offer the support, premium natural materials, customised firmness, sleep health benefits, temperature neutrality, spinal alignment, and pain relief promised by orthopedic bed manufacturers.

What are the disadvantages of an orthopedic mattress? 

It’s important to use care when buying a mattress labelled as orthopedic, as these tend to be too firm for most people who think they need one. You don’t need a high level of firmness to achieve suitable stability; indeed, a mattress that is too firm can actually increase tossing and turning through the night and reduce your overall quality of sleep. 

Who should use an orthopedic mattress?

An orthopedic mattress is only really necessary for someone who has been explicitly prescribed one by an orthopedic surgeon. Even then, it’s important to determine exactly what they mean by the term so you can use their tailored advice to choose a mattress that suits your individual, post-surgery needs.

Can a normal person use an orthopedic mattress?

Yes, anyone can use an orthopedic mattress, as this is simply just a firm mattress. The more important question is whether or not a firm mattress will meet your needs. It’s best to test a few mattresses in person to determine the right support and conformity for your body shape and sleep preferences.

What is the best sleeping position on an orthopedic mattress? 

For most people with back or joint pain, sleeping on their back is the best position to maintain spinal alignment. If you prefer to sleep on your side, use a pillow between your knees to keep them separated and cushion sensitive joints.

Choosing the Right Mattress for Your Spine and Joints

Don’t get distracted by clever marketing – the truth is that orthopedic mattresses are typically a firmer mattress from within a manufacturer’s existing range. If you do have genuine orthopedic concerns, it’s best to discuss these with your doctor and get specific recommendations for a mattress that will meet your joint and spinal health needs. 

If you’re unsure, the expert team at Dreamwool can talk to you about your orthopedic needs and make recommendations around the right materials and firmness to support you.
