How to Choose a Mattress Topper

Your complete Australian guide to finding the perfect topper for better sleep, comfort, and pain relief.

What is a Mattress Topper?

A mattress topper is a removable layer of cushioning that sits on top of your existing mattress. Think of it as a comfort upgrade for your bed—it can transform an old, tired mattress into something that feels brand new, or fine-tune a mattress that's almost perfect but not quite right for your body.

Unlike mattress protectors which primarily shield your mattress from spills and allergens, toppers are designed to genuinely change how your bed feels when you sleep. They range from 2cm to 8cm thick and come in various materials, each offering different benefits for different sleepers.

Are Mattress Toppers Worth It?

The short answer: absolutely—when you choose the right one. A quality mattress topper typically costs between $100 and $500, compared to $1,000 to $3,000+ for a new mattress. For many Australians, that's a smart investment that can extend your current mattress's life by several years while dramatically improving your sleep quality.

Why People Buy Mattress Toppers

  • Revive an ageing mattress that's lost its comfort
  • Add softness to a mattress that's too firm
  • Relieve pressure points causing back, hip, or shoulder pain
  • Regulate sleep temperature (cooler in summer, warmer in winter)
  • Create hotel-quality luxury at home
  • Address specific health conditions like fibromyalgia or arthritis

Find Your Perfect Topper

Different toppers excel at different things. Select your primary need below to discover which type is right for you.

LuxuryFor Luxury & Hotel-Quality Sleep

Ever wondered why hotel beds feel so incredibly plush? The secret is often a premium mattress topper. Hotels invest in high-quality feather and down toppers or dense microfibre options to create that signature cloud-like feel guests love.

To recreate hotel luxury at home, look for toppers with 1000+ GSM (grams per square metre) microfibre filling or genuine duck and goose down. These materials provide exceptional loft and that sink-in comfort that makes you feel pampered every night.

LuxuryFor Ultimate Softness & Comfort

If your mattress feels too firm or you simply crave a softer sleep surface, the right topper can make all the difference. The softest toppers typically feature high-loft microfibre, duck down, or memory foam that contours to your body.

When choosing a topper for softness, thickness matters. A 5-8cm thick topper will create a more noticeable difference than a thinner option. However, keep in mind that ultra-soft toppers may not suit everyone—stomach sleepers and those who need more support may prefer a medium-soft option.

LuxuryFor Back Pain Relief

Back pain affects millions of Australians, and the right mattress topper can provide genuine relief. The key is finding a topper that maintains proper spinal alignment while cushioning pressure points.

Memory foam toppers excel at back pain relief because they mould to your body's unique shape, supporting the natural curve of your spine. For lower back pain specifically, look for a topper that's firm enough to prevent your hips from sinking too deeply, but soft enough to cushion your lumbar region.

A topper thickness of 5-7cm generally works best for back pain sufferers, providing enough material to make a meaningful difference without creating instability.

LuxuryFor Hip Pain & Pressure Points

Hip pain, whether from bursitis, arthritis, or pregnancy, requires a topper that cushions the hip joint while keeping your spine aligned. Side sleepers are particularly prone to hip discomfort because their hips bear more weight in this position.

Memory foam is generally the top choice for hip pain because it distributes your body weight evenly and reduces pressure at the hip point. Pregnant women experiencing hip pain often find relief with a softer memory foam or latex topper that allows the hips to sink slightly while supporting the rest of the body.

LuxuryFor Fibromyalgia & Chronic Pain

Fibromyalgia creates heightened sensitivity throughout the body, making the right sleep surface crucial. People with fibromyalgia often benefit from toppers that minimise pressure points while providing gentle, even support.

Memory foam toppers with a medium-soft feel tend to work well because they cradle tender areas without creating pressure hotspots. Some fibromyalgia sufferers also prefer wool toppers for their temperature-regulating properties, as temperature fluctuations can trigger flare-ups.

LuxuryFor Side Sleepers

Side sleeping is Australia's most popular sleep position, but it does create unique challenges. Your shoulders and hips need enough cushioning to prevent pressure build-up, while your spine needs to stay properly aligned.

The ideal topper for side sleepers is soft enough to let your shoulder and hip sink in, but supportive enough to fill the gap at your waist. Memory foam in the medium to medium-soft range typically work best. A thickness of at least 5cm is recommended to provide adequate contouring.

LuxuryFor Hot Sleepers & Cooling

Australian summers can make sleeping comfortably a real challenge. If you tend to overheat at night or wake up sweating, a cooling mattress topper can be transformative.

Natural materials like bamboo and wool are excellent temperature regulators—they wick moisture away from your body and allow air to circulate. Gel-infused memory foam is another option, using cooling gel particles to draw heat away from your body.

Traditional memory foam, while comfortable, tends to retain heat. If you love the feel of memory foam but sleep hot, specifically look for gel-infused or copper-infused options designed for temperature regulation.

What to Look For in a Mattress Topper

Understanding these key characteristics will help you make a more informed decision when shopping for your perfect topper.

Density (GSM)

GSM stands for 'grams per square metre' and measures how much filling is packed into your topper. For microfibre and down toppers, higher GSM means more loft, better durability, and superior comfort.

Level
Details
500-700 GSM
Light cushioning — budget option, newer mattresses
800-1000 GSM
Medium plushness — most sleepers, good value
1000+ GSM
Luxury, cloud-like — hotel-quality feel, worn mattresses

Loft (Thickness)

Loft refers to how thick and fluffy your topper is. A 'high-loft' topper is thicker and more cushioned. Thicker isn't always better—it depends on your mattress condition and preference.

Level

2-4 cm
Subtle improvement — best for newer mattresses
5-7 cm

Firmness

Topper firmness ranges from extra soft to extra firm. Your ideal firmness depends on your sleep position, body weight, and any pain issues. There are: Side sleepers, back, and stomach sleepers.

Frequently Asked Questions

What Mattress Topper is best?

Selecting the best mattress topper depends on your individual needs, as different types offer varied comfort and support levels. Here are a few factors to consider:

  • Material: Mattress toppers come in various materials like memory foam, microfibre, wool, and down. Memory foam provides excellent support and pressure relief, while microfibre, wool and down toppers offer more breathability and softness.
  • Firmness: If your mattress is too firm, a soft topper can add plushness and restore comfort to an old hard mattress.
  • Thickness: Toppers range from 2 to 8 centimetres thick. Thicker toppers provide more cushioning, but they can also alter the feel of your mattress more dramatically.


Remember, the best mattress topper is ultimately one that fits your personal comfort preferences and sleep needs. Be sure to read customer reviews and consider any sleep issues you have, such as back pain or overheating, when choosing a topper.

Will a mattress topper help back pain?

A mattress topper can provide significant relief for individuals dealing with back pain. Mattress toppers add an extra layer of cushioning to your mattress, which can support your spine's alignment and relieve pressure points. Here's how a mattress topper might help with back pain:

  • Improved support: A mattress topper can enhance the supportiveness of your mattress, helping to maintain the natural alignment of your spine as you sleep. This can help to relieve and prevent back pain.
  • Pressure relief: High-quality mattress toppers can help distribute your body weight evenly across the mattress, relieving pressure points that can cause pain and discomfort in your back.
  • Enhanced comfort: A mattress topper can make your sleep surface more comfortable, which can aid in reducing back pain.


However, it's important to select the right kind of mattress topper for back pain. Look for one that's not too soft or too firm, and choose a material that offers good support and pressure relief, such as memory foam or latex. A topper thickness between 5 to 7 centimetres usually works well for people with back pain. It's also worth noting that while a mattress topper can help alleviate symptoms of back pain, if your mattress is old and sagging, it's unlikely to fix the problem entirely. In such cases, it may be time to consider a new mattress. As with any health condition, it's recommended to consult with a healthcare professional if you have persistent back pain.

What are the benefits of a wool underlay?

A wool underlay, also known as a wool mattress topper, offers numerous benefits that can enhance the quality of your sleep. Made from natural fibres, wool underlays are well-regarded for their warmth and comfort. Here are some key benefits:

  • Temperature Regulation: Wool is an excellent insulator. It helps regulate body temperature, keeping you warm during the cold months and cool during the summer.
  • Comfort: A wool underlay can add a layer of softness and comfort to your bed, helping to cushion your body and relieve pressure points.
  • Moisture Wicking: Wool can absorb moisture and release it back into the air, keeping your bed dry and comfortable throughout the night.
  • Hypoallergenic: Wool is naturally resistant to dust mites, mould, and mildew, making it a good choice for people with allergies or asthma.


Moreover, wool is a sustainable and biodegradable material, making a wool underlay a more environmentally friendly choice compared to synthetic materials. However, it's worth noting that wool underlays require special care when cleaning to maintain their quality and longevity. Despite this, many individuals find that the comfort, warmth, and breathability offered by a wool underlay significantly enhance their sleeping experience. Whether you're looking to add softness to a firm mattress, stay warm during winter, or simply enjoy the luxurious feel of wool, a wool underlay can be an excellent addition to your bed.

What Mattress Topper is best for hip pain?

When dealing with hip pain, the right mattress topper can make a significant difference. It should provide a balance of support and pressure relief to ease discomfort. Here's what to look for in a mattress topper for hip pain:

  • Support: Look for a topper that offers strong support to help maintain proper spinal alignment.
  • Pressure relief: A good mattress topper for hip pain should conform to the body and distribute weight evenly to relieve pressure points around the hips.
  • Material: Memory foam are typically good choices for hip pain as they mould to the body's shape, providing tailored support and pressure relief.


However, remember that individual comfort preferences vary, so it's important to consider your own needs and sleep habits when choosing a mattress topper. If you have severe or persistent hip pain, it's also a good idea to consult with a healthcare professional.

Which Mattress Topper is best for cooling?

Best Cooling Mattress Toppers

For those who tend to sleep hot, a cooling mattress topper can make a significant difference in comfort and sleep quality. These toppers are designed to dissipate heat and promote airflow, helping to keep you cool during the night. Here's what to consider:

  • Material: Certain materials like gel-infused memory foam have natural cooling properties. They can dissipate heat more effectively than standard memory foam.
  • Breathability: Look for a topper that promotes good airflow, which can help regulate temperature.
  • Infusions: Some toppers are infused with cooling gels or materials that draw heat away from the body.


The choice of a cooling mattress topper will ultimately depend on your personal preference and budget. Remember, to help stay cool during the night, also consider factors like your room temperature, bedding materials, and sleepwear.

What's the difference between a mattress topper and a mattress protector?

A mattress protector is a thin, fitted cover designed to shield your mattress from spills, stains, allergens, and dust mites. It doesn't change how your bed feels. A mattress topper is a thick cushioning layer that sits on top of your mattress to change its comfort level—adding softness, support, or pressure relief. Many people use both: a topper for comfort, with a protector over the top to keep everything clean.

How thick should a mattress topper be?

For most people, a 5-7cm thick topper provides the best balance of comfort and support. If your mattress is newer and you just want subtle improvement, 2-4cm may suffice. If your mattress is old and uncomfortable, 8cm+ will make the most dramatic difference. For back pain specifically, 5-7cm tends to work best.

How do I wash a bamboo mattress topper?

Most bamboo toppers can be spot-cleaned with mild detergent and cold water. Some are machine-washable on a gentle cycle—always check the care label. Air-dry flat rather than tumble-drying to maintain the bamboo fibres. Regular airing in fresh air helps keep your topper fresh between washes.

Are memory foam toppers safe? What about off-gassing?

Quality memory foam toppers are safe for most people. New foam products may have a slight odour when first unpacked—this is called off-gassing and typically dissipates within a few days. If you're sensitive to smells, unpack your topper in a well-ventilated room and allow it to air out before use. Look for CertiPUR-US certified foams for added peace of mind.

Can I use a mattress topper with an adjustable bed or split king?

Yes! We offer split mattress toppers specifically designed for adjustable beds and split king configurations. These come in two pieces that can move independently with your adjustable base. Make sure to select the 'split' option when ordering for your adjustable bed.

Are your mattress toppers NDIS approved?

Yes, Sleep Solutions is a registered NDIS provider and many of our mattress toppers are NDIS approved. Mattress toppers can be funded under NDIS for participants who require additional pressure care or comfort modifications for medical conditions. Contact us for assistance with NDIS orders.

How long do mattress toppers last?

With proper care, quality mattress toppers typically last 3-5 years. Memory foam and latex tend to be most durable, while microfibre may need replacing sooner. Signs it's time for a new topper include visible sagging, loss of support, persistent odours, or simply not sleeping as well as you used to.

Which material is best for back pain?

Memory foam or latex toppers (5-7cm, medium-firm) provide the best spinal alignment and pressure relief for back pain. They mould to your body's unique shape while supporting the natural curve of your spine. Avoid toppers that are too soft, as they may cause your hips to sink too deeply and misalign your spine.

Can a mattress topper help with back pain?

Yes. A mattress topper adds an extra layer of cushioning that supports spinal alignment and relieves pressure points. Memory foam or latex toppers (5–7 cm, medium-firm) provide the best pressure relief and spinal support for back pain sufferers.

What thickness mattress topper is best for back pain?

For most people, 5–7 cm provides the ideal balance of comfort and support. If your mattress is older and significantly uncomfortable, 8 cm or thicker will make the most noticeable difference for back pain relief.

What type of mattress topper is best for back pain?

Memory foam are best for back pain. They contour to your body's natural shape, relieving pressure on hips, shoulders, and lower back. Look for medium-firm options — they provide support without being overly soft.
