Best Soft Mattress In Australia (2026)

A soft mattress is about one thing: letting your body sink in. A plush comfort layer cradles your shoulders, hips and lower back so your pressure points settle instead of being propped up, which is exactly what lighter sleepers and dedicated side sleepers need to wake without a numb arm or a sore hip.

The catch is that soft and unsupported are not the same thing. A mattress that only goes soft lets your hips sag through and throws your spine out of line, so the best soft mattresses pair a genuinely plush surface with a supportive core — usually zoned pocket springs — that holds your waist level while the top layer does the cushioning.

We compared the plushest, most pressure-relieving mattresses Australia sells, weighed their real owner reviews and fine print, and kept the six that feel soft without sagging. Here they are for 2026.

What’s the best soft mattress?

The best soft mattress for most Australians in 2026 is the Origin Hybrid. Its plush, quilted TENCEL™ pillow-top and HexaGrid™ comfort layer give you that cushioned, sink-in feel at the surface, while the 7-zone pocket-spring core keeps your hips from dropping through — soft where you want it, supportive where you need it. At sale prices from $503 with a 15-year warranty, nothing else balances plushness and value as well.

Different bodies, different picks. If you want the genuinely softest feel, the Emma Comfort is a plush medium-soft that lets lighter sleepers really sink in (see our full review). On a budget, the Newentor Hybrid delivers a soft, contouring top for under $600. If you cannot decide how soft you want it, the Ecosa lets you re-order its layers at home, and couples who disagree on feel can split the Sleeping Duck half-and-half. The Koala mattress stays popular but sits last here — its flippable layer only goes medium-firm or firm, so there is no genuinely soft side.

1. Origin Hybrid (best soft-feel mattress overall)

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

Soft mattress shoppers want two things that usually fight each other: a plush, cushioned surface and enough support that they do not sink into a hammock. The Origin Hybrid is the rare bed that gives you both. A quilted, machine-washable TENCEL™ pillow-top and a HexaGrid™ ortho comfort layer flex under your shoulders and hips for that soft, sink-in pressure relief, while the 7-zone ErgoCoil™ pocket springs firm up under your waist so your spine stays level.

The result is a genuine medium-firm that feels soft to lie on but never lets your hips drop through — the plush-yet-supportive sweet spot most people mean when they ask for a soft mattress. If you love a cushioned surface without the sagging that pure-soft foam beds develop, this is the one.

It also tops our main best mattress guide on all-round value, with a 120-night trial and a 15-year warranty, the longest safety net on this list.

Pick if...

You want a plush, cushioned surface with real pressure relief, but you do not want a soft mattress that sags at the hips.

Check Current Price

Pros

Targeted shoulder and hip pressure relief: the HexaGrid layer cushions exactly where side sleepers load the mattress
True medium-firm feel: the pressure-relief sweet spot for the majority of side sleepers
Removable, machine-washable cover: rare at this price and easy to keep fresh
120-night trial and 15-year warranty: the longest safety nets on this list

Cons

One firmness only: dedicated soft-mattress fans should look at the Emma Comfort
Heavy to move: a 37 kg queen is a two-person job to rotate
Mixed after-sales reports: a minority of owners describe slow warranty handling

2. Emma Comfort (softest, most plush feel)

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

If you want the genuinely softest feel on this list, the Emma Comfort is it. A plush, cradling medium-soft surface from MemoryAdapt memory foam over pocket springs lets your shoulders and hips settle deeply, so lighter sleepers and side sleepers who found other beds too firm finally get the sink-in cushioning they are after.

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 plush feel treats your body. Emma discounts aggressively, so never pay RRP.

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

Pick if...

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

Body impressions: heavier long-term owners report grooves forming
Not the most supportive: larger side sleepers may want the firmer Origin instead

3. Newentor Hybrid (best value soft mattress)

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 beds go soft by simply being under-built. The Newentor Hybrid earns its softness properly: a gel-infused memory foam top contours to your shoulders and hips for a soft, pressure-relieving surface, and its 7-zone pocket-spring core has a deliberately soft shoulder zone the brand markets for pain-free side sleeping, with firmer coils under the lumbar to stop the softness turning into sag.

The antibacterial bamboo-charcoal cover 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 — a soft, contouring feel for foam-slab money.

Pick if...

You want a soft, contouring surface with zoned support on a proper hybrid, without spending big.

Check Current Price

Pros

Dedicated soft shoulder zone: zoned springs cushion the shoulder while supporting the waist
Certified materials: CertiPUR-US foams plus an OEKO-TEX Standard 100 cover
Cool bamboo-charcoal cover: naturally moisture-wicking and breathable

Cons

Cover is not removable: pair it with a washable protector

4. Ecosa Mattress (best adjustable softness)

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

The trouble with buying soft online is that you cannot tell whether you want plush or just a touch of give until you have slept on it. The Ecosa solves that: unzip the cover and reorder the three foam layers to shift the feel between its plush, medium and firm configurations at home, so if your first choice feels too soft you can dial it back in minutes.

Its open-cell contour foam cushions like latex but breathes better, and a five-zone ergonomic base keeps your hips supported so the softness never sags. The removable, washable TENCEL™ cover and included waterproof protector keep it fresh, backed by 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 finding your exact soft setting, nothing here beats it.

Pick if...

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

Check Current Price

Pros

Three firmness settings in one bed: reorder the layers to find your exact side-sleeping feel
Breathable contour foam: supports like latex while sleeping cooler
Removable washable cover: plus a waterproof protector included in the box
15-year warranty: among the longest here

Cons

All-foam, not hybrid: lacks the spring responsiveness of the Origin or Newentor
Pricier than the value picks: queen sits at $1,240 before member discounts
Adjusting takes a few minutes: you have to unzip and reshuffle the layers

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 love a soft feel but your partner does not, the Sleeping Duck SD MACH II is the answer no one else offers: order it half soft, half firmer so each side of the bed is tuned to its sleeper, and swap the comfort layers later if your preference changes.

The AirGrown foam creates a near-weightless, plush cradle that suits soft-mattress fans, 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 you can order soft, it earns its place mid-list.

Pick if...

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

Check Current Price

Pros

Split firmness for couples: order it half medium and half firm so each side suits its sleeper
Swappable comfort layers: re-tune the feel years later instead of replacing the bed
Weightless pressure relief: AirGrown foam cradles the shoulders and hips
Highest rating here: 4.8/5 across 5,700+ reviews

Cons

Premium price: a queen is $1,649, well above the value picks
Overkill for solo sleepers: much of the value is in the split-firmness option
Firm-half can feel very firm: dial in your side carefully during the trial

Size	Dimensions (L×W×H)	Price
Single	188 × 92 × 31 cm	$999
King Single	203 × 107 × 31 cm	$1,099
Double	188 × 138 × 31 cm	$1,349

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 soft-mattress shoppers specifically, though, it comes last. Its flippable layer only switches between medium-firm and firm — there is no genuinely plush side — so it runs harder than most people looking for ‘soft’ actually want, and being all-foam it lacks the zoned spring support the hybrids above use to cushion the hips without sagging. It is a good mattress; it is just built firmer than this list calls for.

Pros

Excellent motion isolation: strong for restless couples
Flippable firmness: switch between medium-firm and firm at home
Soft TENCEL cover: breathable and moisture-managing
Fast metro delivery: often same-day in major cities

Cons

No plush side for side sleepers: both firmness options run firm under the shoulder
All-foam core: lacks the zoned spring support the hybrids use for hip relief
Price has crept up: from $890 against better-equipped hybrids

Size	Dimensions (W×L×H)	Price
Single	92 × 188 × 25 cm	$890
King Single	107 × 203 × 25 cm	$990
Double	138 × 188 × 25 cm	$1,150
Queen	153 × 203 × 25 cm	$1,249
King	183 × 203 × 25 cm	$1,490

From $890 · 120-night trial · up to 10-year warranty · flippable medium-firm/firm comfort layer. Prices checked July 2026 — always confirm on the brand site.

How we choose soft mattresses

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

Judged the plush comfort layer — how well the surface cushions the shoulders and hips and relieves pressure, because that sink-in feel is the whole point of a soft mattress.
Checked that soft did not mean saggy — we favoured beds that pair a plush top with a zoned or hybrid support core that keeps the waist level, and marked down any that let the hips drop through.
Weighed feel and body type — lighter sleepers do best on medium-soft, heavier sleepers usually need more support under the softness, so adjustable and split-firmness options scored well.
Aggregated verified owner reviews across ProductReview.com.au, CHOICE and Australian Reddit communities, and re-checked those scores at this update.
Scrutinised the fine print — trial length matters twice as much with a soft mattress, because a plush feel takes a couple of weeks to judge fairly.

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.

What to look for in a soft mattress

1. A genuinely plush comfort layer

Softness lives in the top few centimetres. Look for a thick memory-foam, gel-foam or pressure-grid comfort layer that lets your shoulders and hips sink in. This is what turns a mattress from ‘firm with a soft cover’ into one that actually cradles you.

2. Support underneath so it does not sag

The mistake people make is buying pure softness. Without a supportive core your hips sink through and your spine bows, which causes the lower-back ache soft mattresses are wrongly blamed for. Zoned pocket springs or a firm base layer under the plush top is what keeps a soft mattress healthy.

3. The right level of soft for your weight

Lighter sleepers (under about 70 kg) can enjoy a true medium-soft; average and heavier sleepers usually want a plush surface over a firmer core, or an adjustable bed, so they get the cushioned feel without bottoming out.

4. Motion isolation

Soft foam and memory-foam comfort layers naturally absorb movement, so a good soft mattress is usually excellent for couples. If you share the bed, this is a bonus that comes almost for free with the plush picks here.

5. Trial length

A soft feel takes longer to judge than a firm one — your body needs a week or two to settle into it. Every mattress here comes with a trial of at least 100 nights, and the Emma Comfort gives you 150.

FAQs

Are soft mattresses bad for your back?

Only if they are soft all the way through. A mattress that is plush on top but supportive underneath — like the zoned hybrids on this list — keeps your spine aligned while relieving pressure, which is good for most backs. The back pain people blame on soft mattresses usually comes from cheap beds that sag because they have no support core.

Is a soft or medium mattress better for side sleepers?

Side sleepers generally do best between medium-soft and medium-firm, because the shoulder and hip need to sink in while the waist stays supported. Lighter side sleepers lean softer (the Emma Comfort), heavier ones lean firmer (the Origin). Adjustable options like the Ecosa let you find your exact point.

Do soft mattresses sag faster?

A well-built soft mattress with a supportive core lasts as long as any other — every pick here carries a 10 to 15-year warranty. Cheap all-foam soft mattresses without a proper base are the ones that develop body impressions early, which is exactly why we did not include any.

How soft is too soft?

If you sink so far that rolling over feels like effort, or you wake with lower-back stiffness, the mattress is too soft for your body and support needs. That is the value of a long trial and of adjustable beds: you can feel it within a couple of weeks and, with the Ecosa or Sleeping Duck, re-tune it rather than return it.

Can I make a firm mattress softer instead?

Yes, a plush mattress topper is the cheapest way to add a soft, cushioned surface to a mattress that is too firm. It will not fix a bed that sags, but it is a low-cost way to test whether you actually prefer a softer feel before committing to a new mattress.
