Best Mattress For Side Sleepers in Australia

1. Origin Hybrid (best for side sleepers overall)

Firmness: Medium-Firm
Price: From $503 (Queen ~$729 on sale)
Trial period: 120 Nights
Warranty: 15 Years
Rating: ★★★★★ (4.6/5)
Check Deal

Side sleepers live and die by pressure relief, and the Origin Hybrid is built around it. Its signature HexaGrid™ ortho layer flexes under the shoulder and hip so those pressure points sink in instead of being propped up, while the 7-zone ErgoCoil™ pocket springs firm up under the waist to hold your spine level — the exact combination a side sleeper needs to wake without a dead arm or sore hip.

It sits at a genuine medium-firm, which is the pressure-relief sweet spot for most side sleepers: soft enough to cushion, supportive enough to stop the hips dropping through. The removable, machine-washable TENCEL™ cover and breathable hybrid core are a bonus, and it tops our main best mattress guide on all-round value.

With a 120-night trial and a 15-year warranty — the longest here — you get a full season to test how your shoulders and hips respond, backed by the best fine print on the list.

Pick if...

You want proven shoulder-and-hip pressure relief on a balanced medium-firm hybrid, at the best price on this list.

2. Emma Comfort (best for softer side sleepers)

Firmness: Medium-Soft
Price: From $679 (RRP $1,029)
Trial period: 150 Nights
Warranty: 10 Years
Rating: ★★★★★ (4.8/5)
Check Deal

Some side sleepers, especially lighter ones, need to sink further before the mattress catches their shoulder. That is where the Emma Comfort shines: a plush, cradling medium-soft feel from MemoryAdapt foam over pocket springs that lets the shoulder and hip settle deeply while the spring core keeps the spine supported.

It is the crowd favourite too — a 2026 ProductReview.com.au award winner with more than 7,000 five-star reviews — and its 150-night trial is the longest here, which matters when you are learning how a softer feel treats your pressure points. Emma discounts aggressively, so never pay RRP.

The honest caveats: the medium-soft feel divides opinion, and heavier side sleepers have reported body impressions forming over time, so bigger bodies may prefer the firmer support of the Origin.

Pick if...

You are a lighter side sleeper who likes to sink into a plush, cradling surface and want the longest trial on the list.

3. Newentor Hybrid (best value pressure relief)

Firmness: Medium-Firm (6/10)
Price: From $388.50 (Queen $598.50)
Trial period: 120 Nights
Warranty: 10 Years
Rating: ★★★★★ (4.4/5)
Check Deal

Most budget mattresses treat every part of your body the same. The Newentor Hybrid does not: its 7-zone pocket-spring core mixes soft and firm coils, and zone two is a deliberately soft shoulder zone the brand markets specifically for pain-free side sleeping, with firmer coils under the lumbar to keep the waist level.

On top sits a gel-infused memory foam layer that contours to the shoulders and hips, under an antibacterial bamboo-charcoal cover that keeps things cool. The foams are CertiPUR-US® certified and the cover is OEKO-TEX® Standard 100, which is unusually thorough at this price.

With a 120-night trial, a 10-year warranty and a queen that regularly sells under $600, it is the value pick of this list by a distance — you are paying foam-slab money for genuine zoned pressure relief.

Pick if...

You want zoned shoulder-and-hip pressure relief on a proper hybrid without spending big.

4. Ecosa Mattress (best adjustable firmness)

Firmness: Adjustable (Plush / Medium / Firm)
Price: From $870 (Queen $1,240)
Trial period: 100 Nights
Warranty: 15 Years
Rating: ★★★★★ (4.7/5)
Check Deal

Side sleepers often cannot tell whether they want medium or plush until they have slept on it for a week. The Ecosa solves that with a genuinely useful trick: unzip the cover and reorder the three foam layers to switch between plush, medium and firm at home, so you can dial in the exact amount of shoulder give you need.

Its open-cell contour foam supports like latex but breathes better, and a five-zone ergonomic base targets pressure across the shoulders and hips. The removable, washable TENCEL™ cover and included waterproof protector keep it fresh, and Ecosa backs it with a 15-year warranty.

It is all-foam rather than hybrid, so it lacks the spring bounce of the Origin or Newentor, and at $1,240 in queen it is priced above the value picks — but for adjustability, nothing here beats it.

Pick if...

You are not sure how soft you want it and would rather change the firmness at home than gamble on one setting.

5. Sleeping Duck SD MACH II (best customisable premium pick)

Firmness: Customisable (Medium / Firm / Half-half)
Price: From $999 (Queen $1,649)
Trial period: 100 Nights
Warranty: 10 Years
Rating: ★★★★★ (4.8/5)
Check Deal

If you and your partner sleep on your sides but disagree on feel, the Sleeping Duck SD MACH II is the answer no one else offers: you can order it half medium, half firm, so each side of the bed is tuned to its sleeper. The comfort layers are swappable later too, so you are never locked in.

The AirGrown foam creates a near-weightless, pressure-relieving cradle that suits side sleepers, and the removable, washable bamboo cover is as premium as they come. It is the highest-rated mattress here at 4.8/5 across more than 5,700 reviews.

The catch is price: a queen is $1,649, well above the value picks. But if you want a genuinely customisable, made-to-last Australian hybrid, it earns its place mid-list.

Pick if...

You share the bed with a partner who wants a different firmness, or you want a premium hybrid you can re-tune down the track.

6. Koala mattress (popular flippable pick)

Firmness: Flippable (Medium-Firm / Firm)
Price: From $890
Trial period: 120 Nights
Warranty: Up to 10 Years
Rating: ★★★★★ (4.7/5)

Australia’s most recognisable mattress still deserves a look. The Koala is built on Kloudcell® foam under a soft TENCEL™ cover, with excellent motion isolation and a flippable comfort layer, all backed by a 120-night trial and famously fast metro delivery.

For side sleepers specifically, though, it comes last. Its flippable layer switches between medium-firm and firm — there is no genuinely plush side — so it runs harder than most side sleepers want under the shoulder, and being all-foam it lacks the zoned spring support the hybrids above use to relieve hip pressure. It is a good mattress; it is just built more for back and combination sleepers than dedicated side sleepers.

How we choose mattresses for side sleepers

There is no lab-coat theatre here — just the same process applied to every mattress, whether the brand works with us or not. For side sleepers specifically we:

• Prioritised shoulder and hip pressure relief — the two points that carry your weight on your side. Beds that jam the shoulder or let the hip sag through were marked down.
• Checked spinal alignment — the waist needs support while the shoulder and hip sink, so we favoured zoned and hybrid constructions that do both.
• Weighted feel and firmness — most side sleepers do best between medium-soft and medium-firm, so adjustable and split-firmness options scored well.
• Aggregated verified owner reviews across ProductReview.com.au, CHOICE and Australian Reddit communities, re-checked at this update.
• Scrutinised the fine print — trial length matters twice as much when you are learning how a new feel treats your pressure points.

Sleep Society may earn a commission if you buy through links on this page. That never changes the order: Koala sits last and carries no links at all, which should tell you how the sausage is made.
