Side sleepers, raise your hand if you’ve woken up with a stiff shoulder or sore hip—we’ve all been there. Around 60% of adults sleep on their side, and this position puts extra pressure on your joints if your bed isn’t supportive enough.
The best mattress topper for side sleepers can fix this, adding the perfect balance of cushioning and support to cradle your shoulders and hips, align your spine, and turn a restless night into a restful one.
If you’re in Australia searching for the best mattress topper for side sleepers in Australia, this guide breaks down everything you need to know, from the best types to top picks tailored for Aussie side sleepers.
In this article
What Type of Mattress Topper is Best for a Side Sleeper?
- Memory Foam: This is the gold standard. Memory foam reacts to body heat and pressure, molding to your shape. According to Sleep Foundation, memory foam is highly effective for pressure relief in lateral sleepers.
- Latex: A great eco-friendly alternative. It’s bouncier than foam and doesn’t give you that "sinking" feeling, making it easier to switch sides during the night.
- Down and Down Alternative: These are incredibly soft, but they often lack the structural support needed to align the spine. If your bed is just a little bit too firm, these are fine, but for chronic pain, stick to foam.
Density also matters to side sleepers, look for a thickness of at least 5cm to 10cm. Anything thinner won't provide enough "give" for your shoulders.
3 Best Mattress Toppers for Side Sleepers in Australia
2.1 Newentor Cooling Mattress Topper (Best Mattress Topper for Hot Sleepers)
If you’re a side sleeper who gets hot at night, the Newentor Cooling Mattress Topper is the best mattress topper for side sleepers who want comfort and coolness in one. This topper is designed with hot sleepers in mind, featuring PCM support sponge and Cool-Feeling Green Flow™ fabric that’s OEKO-TEX certified, skin-friendly, and perfect for humid Australian weather.
At 7cm thick, it’s the ideal thickness for side sleepers—soft enough to cushion your shoulders and hips but firm enough to keep your spine aligned. The gel-visco flow™ memory foam provides zero-pressure support, conforming to your body shape without making you sink too deep. It also has a dual anti-slip design (anti-slip dots and an adjustable elastic band) to keep it in place, even if you toss and turn all night—no more waking up to a topper halfway off your bed.

If you’re on a budget but still want a comfortable topper for side sleeping, the Muscle Mat Mattress Topper is a solid option—though it’s not as supportive as the Newentor models. This topper is 7–8cm thick (marketed as 10cm, but it compresses slightly after expanding) and features a plush, cloud-like feel, thanks to its 100% high-density cotton top layer and premium high-GSM polyester fill.
It has a square-quilted pattern to keep the filling evenly distributed, so you won’t have lumps or clumps forming over time. The deep 40cm fitted skirt hugs your mattress securely, helping to prevent slipping—though some users report it still shifts a bit for active sleepers. It’s soft and comfortable, making it great for side sleepers who prefer a plush surface, but it lacks the pressure relief and spine support of memory foam toppers.
Pros
- Budget-friendly option, priced at around AUD $129 for a single size, ideal for side sleepers on a tight budget.
- Features a plush, cloud-like feel, thanks to its 100% high-density cotton top layer and premium high-GSM polyester fill.
- 7–8cm thick (marketed as 10cm), offering extra softness for side sleepers who prefer a plush surface.
- Equipped with a square-quilted pattern to keep the filling evenly distributed, avoiding lumps or clumps over time.
- Has a deep 40cm fitted skirt that helps keep the topper securely in place on the mattress.
Cons
- Less supportive than Newentor mattress toppers, lacking the pressure relief and spine support that side sleepers need (especially those with back or joint pain).
- Not suitable for hot sleepers, as it traps heat—uncomfortable during humid Aussie summers.
- Poor durability, with many users reporting durability issues.
- May still shift a bit for active sleepers, despite the deep fitted skirt.
FAQs about Mattress Topper for Side Sleeper
Q1: What thickness mattress topper is best for side sleepers?
The best thickness for side sleepers is 5–10cm. A 7cm topper works well for medium-firm mattresses, while a 10cm topper is better for very firm mattresses. Avoid toppers thinner than 5cm (not enough cushioning) or thicker than 8cm (too much sinking, which misaligns your spine).
Q2: Is memory foam or latex better for side sleepers?
Both are great, but it depends on your preferences. Memory foam is better for pressure relief (it conforms to your body), making it ideal for side sleepers with shoulder/hip pain. Latex is more responsive and breathable, making it better for side sleepers who don’t like the “sticky” feel of memory foam or who run hot (but it’s more expensive).
Q3: Can a mattress topper fix a too-firm mattress for side sleepers?
Yes! A high-quality memory foam or gel foam topper is the best way to soften a too-firm mattress for side sleepers. The best mattress topper for side sleepers will add cushioning to relieve pressure on your joints while still providing enough support to keep your spine aligned—no more waking up sore from a rock-hard mattress.
Q4: How often should I replace my mattress topper for side sleeping?
Most mattress toppers last 2–7 years, depending on quality and use. Memory foam toppers last 5–7 years, while budget options last 2-3 years. Replace yours if you notice sagging, lumps, or if it no longer relieves pressure on your shoulders and hips.
Bottom Lines
For side sleepers, the best mattress topper balances comfort, support, and suitability for Australia’s climate. Skip budget options lacking support—Newentor mattress toppers (Cooling and Memory Foam models) deliver targeted pressure relief, cooling, and durability, making them the top choice for pain-free, restful sleep every night.
