Best Single Mattress Australia

1. Newentor Hybrid (best single mattress overall)

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

Most cheap singles are a bare slab of foam that bottoms out inside a year. The Newentor Hybrid breaks that rule: for $388.50 in a single you get a proper 7-zone pocket-spring core, with firmer coils under the middle to keep a spine level and softer zones at the shoulders. For a growing child or a guest bed you only use occasionally, that is a genuine mattress, not a compromise slab, at a throwaway price.

It is well finished for the money. A gel-infused memory foam comfort layer keeps the surface from feeling harsh, the bamboo-charcoal cover runs cool for restless little sleepers, and the foams are CertiPUR-US certified under an OEKO-TEX Standard 100 cover, which matters in a child’s room. At 25cm high it also sits low enough to stay behind a bunk guard rail, and the 120-night trial plus 10-year warranty cover the years ahead.

The compromises are minor and honest. The cover does not unzip for washing, so a protector is essential in a kids’ room, and aftercare is leaner than the big brands. For the best single per dollar, none of that outweighs the price.

Pick if...

You want the most support and durability you can get for the least money, whether it is for a child’s room, a guest bed or a bunk.

2. Origin Hybrid (best premium single)

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

If the single has to survive years of jumping, spills and hand-me-downs, the Origin Hybrid is the pick. It pairs 7-zone ErgoCoil pocket springs with a HexaGrid comfort layer for a true medium-firm feel that suits older kids, teens and guests alike, and a single starts from just $503 on Origin’s near-permanent sale.

What lifts it above the other singles is the fine print, which is exactly what matters in a child’s room. The TENCEL cover is removable and machine-washable, so an accident is a wash rather than a write-off, and the 15-year warranty and 120-night trial are the longest safety nets on this list. It also tops our main best mattress guide on all-round value.

At 27cm it is the tallest bed here, so on a bunk check it still clears the guard rail before you buy. It also comes in one firmness only, but as a single you buy once and keep for years, it is the safest long-term choice.

Pick if...

You want a single that survives childhood, with a washable cover for spills and the longest warranty on this list.

3. Emma Comfort (best big-brand single)

Firmness: Medium-Soft
Price: From $559 (current sale)
Trial period: 150 Nights
Warranty: 10 Years
Rating: ★★★★★ (4.8/5)

The Emma Comfort is proof a big, award-winning brand can still be a sensible single. It is Australia’s most awarded mattress, a repeat ProductReview.com.au winner with thousands of five-star ratings, and Emma discounts so aggressively that a single frequently drops to around $559, cheap enough for a spare room or a child’s bed.

The build is a genuine three-layer foam comfort system over pocket springs, giving a medium-soft feel with excellent motion isolation, which is handy when a restless child shares or climbs in. You also get the longest trial on this list at 150 nights, so there is plenty of time to be sure it suits before the sale price is locked in. At 25cm it sits low enough for a bunk.

The only real catch is the feel: at around 6.7/10 it is on the softer side, so a teen or guest who prefers firm support may want the Newentor or Origin. And because the price swings with each sale, always check the current deal rather than assume RRP.

Pick if...

You want a big-brand, heavily reviewed single with a long trial, and you can time your purchase to one of Emma’s frequent sales.

4. Ecosa Mattress (best adjustable single)

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 Ecosa is the pick for a child who is still growing, because it can be three mattresses in one. Unzip the cover and you reorder the internal layers to switch between Plush, Medium and Firm, so as a child grows and their needs change you adjust the feel at home rather than buy a new bed. A single is $870.

Underneath that flexibility is a well-made all-foam single: a breathable contour foam that supports a little like latex while sleeping cooler, a removable washable cover, and a waterproof protector included in the box, which is exactly what a kids’ bed wants. At 25cm it fits a bunk, and the 15-year warranty means it outlasts the childhood.

A single at $870 is only cheap by mattress standards, not by budget-single standards, so it costs more than double the Newentor. But Ecosa runs frequent sales, and for a growing child the ability to re-tune the firmness at home can be worth the stretch.

Pick if...

You are buying for a growing child and want to switch between Plush, Medium and Firm at home rather than replace the bed.

5. Koala mattress (popular 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 deserves a mention, and plenty of parents search for it by name for a kids’ room. The Koala single is built on Kloudcell foam under a soft TENCEL cover, with excellent motion isolation, a flippable comfort layer that switches between medium-firm and firm, a 120-night trial and famously fast metro delivery. At 25cm it fits a bunk fine.

On value, though, it lands last. A single from $890 costs more than the Newentor, Origin and sale-priced Emma while giving no extra support in return, and being all-foam it lacks the zoned spring support the hybrids above use to keep a growing spine level. It is a good bed and a safe brand; it is just not the best use of a tight single-bed budget when the picks above do more for less.

How we choose single 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 single mattresses specifically we:

• Judged value, not just price — the cheapest single is no bargain if it sags, so we weighed what support and materials you actually get for the money.
• Checked the support core — a real pocket-spring or dense-foam core that keeps a growing spine level, rather than a thin slab that bottoms out.
• Checked mattress height for bunks — a single that sits too tall clears the guard rail, so we noted the profile of every pick.
• Read the fine print — trial length, warranty and washable covers, because a kids’ bed has to survive spills and years of use.
• Aggregated verified owner reviews across ProductReview.com.au, CHOICE and Australian Reddit communities, and re-checked those scores at this update.
• Confirmed live single-size pricing — every price is the actual single, checked on the brand’s own page in July 2026, with sale prices flagged where they swing.

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