How to choose the best mattress for lower back pain

The wrong mattress could be making things worse, while the right one could change how you feel every morning.

Back pain is one of the most common health complaints worldwide, with around 4 million (16%) of Australians estimated to be living with lower back pain [1]. So, if you’re waking up feeling sore, you’re definitely not alone. 

And turns out, your mattress might have more to answer for than you think. If it's not supporting your spine properly, it could be making your pain worse.

The good news is that the right mattress can make a genuine difference. Not just to how well you sleep, but to how your body feels when you get up in the morning and move through your day. 

In this guide, we'll walk you through everything you need to know about choosing the best mattress for lower back pain; from what causes back pain in the first place, to the key features worth looking for, to the best sleeping positions for keeping your spine happy. We'll also look at the Koala Luxe Mattress, which ticks a lot of the boxes worth looking for when back pain is a factor.

Whether you've been struggling for years or you're just starting to notice some morning stiffness, this guide will help you find a better night's sleep and hopefully, a whole lot less pain.

Let’s make experiencing a painful lower back after sleeping the exception, not the rule!

Lower back pain symptoms

Lower back pain is one of the most common health conditions in the world. According to the World Health Organisation, 619 million people experienced it in 2020 and it’s the single leading cause of disability worldwide [2]. 

Most people will experience it at least once in their lifetime, with around 90% of cases falling into the non-specific category, meaning there's no single identifiable cause. It can be short-lived, lasting a matter of weeks, or develop into a chronic condition that hangs around for 3 months or more. 

Common symptoms of lower back pain include:

  • Dull, aching or sharp stabbing pain

  • Stiffness or difficulty in bending or moving

  • Restricted movement and muscle spasms

  • Pain or numbness that radiates down one or both legs

  • Disrupted sleep and changes in mood

Causes of lower back pain

Annoyingly, back pain rarely has a single, obvious cause. It usually develops from a combination of stress on the surrounding muscles, ligaments and joints and occasionally, the spinal discs themselves. In fact, most back pain is classified as ‘non-specific’, meaning it builds up gradually through everyday habits. 

These can include:

  • Sitting for long stretches

  • Not moving enough

  • Repetitive bending or twisting

  • Heavy physical work

  • Poor posture over time

Signs your mattress is causing lower back pain

You spend roughly a third of your life in bed [3], so it stands to reason that the mattress beneath you plays a significant role in both sleep quality and how your body feels come morning. 

A mattress that isn't right for you can do more than leave you feeling groggy. It can actively contribute to back pain or aggravate issues you already have, especially if it's failing to keep your spine properly supported and aligned. Night after night of poor support adds cumulative strain to your back, leaving your body without the recovery time it needs.

The flip side is equally true. The right mattress can actively support your spine and help ease pain while you sleep, making a real difference to how you feel during the day. While we can’t promise you’ll bounce out of bed, a supportive mattress can help you get pretty close. 

So how do you know if your mattress is part of the problem? There are some telling signs worth looking out for:

  • Morning stiffness or soreness that gradually fades as you get moving

  • A mattress that's more than a decade old

  • Visible dips, sags or uneven patches in the surface

  • Restless nights spent shifting around in search of a comfy position

  • Waking up repeatedly throughout the night

  • Sleeping noticeably better elsewhere (when even an average hotel bed feels like a step up)

If several of these ring true, your mattress may be playing a bigger role in your back pain than you realise.

Best mattress for lower back pain 

Most experts recommend a medium-firm mattress for those dealing with lower back pain and research backs this up, showing that this level of firmness supports comfort, sleep quality and spinal alignment, all of which can help reduce pain over time [3].

But firmness alone isn't the whole story. Equally important is how well a mattress supports your spine throughout the night. A mattress with targeted support zones works with your body's natural curves, relieving pressure on key joints and keeping your spine in a neutral position; the sweet spot for overnight recovery.

The Luxe Mattress is designed with exactly this in mind. Its 7-zone support core contours to your body's natural shape, offering cushioning where you need softness, like your hips and shoulders and firmer support where it matters most, keeping your back properly aligned from the moment you lie down.

It's also built with our Kloudcell® foam, which responds instantly as you move. Unlike traditional memory foam that can feel slow and sinking, Kloudcell® adapts quickly to position changes, meaning less disruption and consistent support across your whole body throughout the night.

Considerations for choosing the best mattress for lower back pain

Choosing a mattress when you have lower back pain isn't just about what feels comfortable in the moment; it's about what your body needs over the long term. While there's no one-size-fits-all answer, there are a few key factors worth weighing up before you buy.

Firmness

Firmness is often the first thing people consider and for good reason. A mattress that's too soft won't provide enough support, allowing your hips to sink and your spine to fall out of alignment. 

Too firm and it can create pressure points, particularly around the hips and shoulders. For most people with lower back pain, a medium-firm mattress hits the right balance: supportive enough to keep your spine neutral, while still offering enough give to relieve pressure where it's needed most.

That said, the right firmness also depends on your sleep position and body weight, so it's worth factoring those in rather than going purely by feel. The Luxe Mattress sits in the plush and comfort sweet spot; supportive enough to cradle your back and keep it in alignment, cushioned enough to feel genuinely comfortable. 

Support and zoning

Firmness and support aren't the same thing. A mattress can feel firm and still fail to support your spine properly. What you're really looking for is a mattress that maintains your spine's natural curve throughout the night and the best way to achieve this is through zoned support.

Zoned mattresses are designed with different areas of firmness mapped to different parts of the body; softer zones for pressure points like the shoulders and hips, and firmer zones beneath the lower back and lumbar region. 

The Luxe Mattress features a 7-zone support core that does exactly this, contouring to your body's natural shape and keeping your spine in alignment from the moment you lie down to the moment you wake up.

Material

The inside of your mattress has a big say in how well you sleep. Different materials affect everything from support and pressure relief to temperature regulation; each material has its strengths and its limitations.

  • Memory foam contours closely to the body and does a great job of relieving pressure points. Traditional versions can feel a little slow to respond when you shift position though.

  • Latex is naturally responsive and durable, with a cooler sleep surface than most foams. It's a solid option, though it can feel quite firm and is often one of the pricier materials on the market.

  • Hybrid mattresses pair a coil base with foam or latex comfort layers, offering a mix of support and pressure relief. Motion isolation isn't their strongest suit though, so if you share a bed with a restless sleeper, you’ll probably feel their movements throughout the night.

  • Responsive foam takes the best of what foam has to offer: close contouring, pressure relief and adaptability, without the sluggish, heat-trapping downsides of traditional memory foam. It responds instantly as you move, keeping you supported without that heavy, sinking feeling.

The Koala Luxe Mattress is built with Kloudcell® foam; Koala's own responsive foam that reacts instantly as you shift position throughout the night. It delivers consistent support across your whole body without the sinking sensation often associated with memory foam, making it a strong option for anyone looking to wake up with less pain and more energy. 

Say goodbye to low back pain upon waking up!

Best sleeping positions for lower back pain

Your mattress and your sleeping position are in this together; get one wrong and the other can only do so much. While some positions naturally support spinal alignment, others place unnecessary strain on the lower back and over time, that strain can add up. 

Here's a breakdown of the most common sleeping positions and how they affect your back.

Sleeping on your back

Back sleeping is widely considered the best position for lower back pain. When you lie on your back, your weight is distributed evenly across the widest surface area of your body, reducing pressure on any single point. 

Placing a pillow beneath your knees helps maintain the natural curve of your lumbar spine, taking even more strain off your lower back.

Sleeping on your side

Side sleeping is another good option, particularly for those who find back sleeping uncomfortable. The key is keeping your spine in a straight, neutral line, which means avoiding curling too tightly into the foetal position. 

Placing a pillow between your knees helps keep your hips, pelvis and spine properly aligned and reduces the twisting pressure that can aggravate lower back pain.

Sleeping on your stomach

Stomach sleeping is generally considered the worst sleeping position for lower back pain. It flattens the natural curve of your spine and forces your neck to one side for hours at a time, placing significant strain on both your lower back and your neck. 

If you find it difficult to break the habit, placing a pillow beneath your pelvis can help reduce some of the pressure on your lumbar spine.

The position that works best for you

At the end of the day, the best sleeping position is simply the one you wake up from without pain. If you're not sure where to start, side or back sleeping with good pillow support is a solid foundation. And, a mattress with proper zoned support will do the rest of the work while you sleep.

Lower back pain is incredibly frustrating but your mattress is actually one of the easiest things you can change that can make a genuine difference to how your body feels when you wake up. Now you know what to look for: the right firmness, proper zoned support and a sleeping position that works with your body, rather than against it. 

And, the Luxe Mattress ticks all those boxes; designed with back support at its core and with 120 days to try it for yourself, in your own home, it’s a no-brainer. That means no showroom, no salesperson, just actual sleep so you can see for yourself. Your back has put up with enough. It might be time to give it a proper night's sleep.
