Best Mattress for Pregnancy in Australia (2026 Guide)
Quick Answer
What is the best mattress for pregnancy in Australia? The Newentor Hybrid Pro — pregnancy means months of side sleeping, and the Pro's slightly softer, pressure-relieving surface cushions the hips and shoulders while its dual-spring core supports your changing weight. Reinforced edges also make getting in and out of bed easier in the third trimester.
Key rule: from around 28 weeks, Australian health guidance recommends going to sleep on your side — so your mattress needs to make side sleeping genuinely comfortable.
Sleeping hot? Look at the whole build: a pocket-spring core gives air room to move inside the mattress and a breathable cover helps heat escape — though the comfort layer on top also affects how warm any mattress sleeps.
Test it at home: every Newentor mattress comes with a 120-night risk-free trial and a 10-year warranty.
How pregnancy changes your sleep
Almost everything about sleep changes across the nine months: your weight and its distribution shift, your joints loosen, you run warmer, you get up more often at night, and from mid-pregnancy onward you'll be spending most of the night on your side. A mattress that was fine before can suddenly feel too hard at the hips, too hot, and too hard to climb out of.
None of that means you must buy a new mattress — but if yours is already sagging, too firm for side sleeping, or overheating you, pregnancy is when you'll feel it most.
Why sleeping on your side matters in pregnancy
From around 28 weeks, Australian safe-pregnancy guidance recommends going to sleep on your side — research links side sleeping in late pregnancy to a significantly lower risk of stillbirth compared with going to sleep on your back. The reassuring part of the same guidance: the position you fall asleep in is what matters, and if you wake up on your back, don't panic — just settle back onto your side. See Red Nose Australia for the full guidance, and talk to your midwife or doctor about what's right for you.
For your mattress, this means one thing: side sleeping has to be comfortable enough to sustain all night, every night, for months.
What to look for in a mattress during pregnancy
Pressure relief at the hips and shoulders. Side sleeping concentrates weight on two points. A too-firm surface leaves pregnant side sleepers with numb arms and aching hips — the single most common complaint.
Support that handles changing weight. Under the comfort layer you still need a proper spring core, so your spine stays level as your weight increases and shifts forward.
Breathability. Pregnancy raises your body temperature. A pocket-spring core gives air somewhere to move and a breathable cover helps heat escape — but check the whole build, because a thick foam comfort layer can sleep warm on any mattress type.
Motion isolation. You'll change positions and get up far more often — individually wrapped springs keep that from waking your partner (and vice versa).
Edge support. By the third trimester, pushing up from the edge of the bed is a real workout. Reinforced edges give you something solid to sit on and push off from.
What changes by trimester
| Stage | What changes | What helps |
|---|---|---|
| First trimester | Fatigue, tenderness, running warmer | Breathable mattress, comfortable in any position |
| Second trimester | Side sleeping becomes the norm; hips start to ache | Pressure relief at hips and shoulders; a pillow between the knees |
| Third trimester | Side sleeping recommended; frequent night waking; harder to get up | Sustained side-sleeping comfort, motion isolation, reinforced edges |
Our top pick for pregnancy: the Newentor Hybrid Pro
The Newentor Hybrid Pro fits the pregnancy checklist point for point: a slightly softer, pressure-relieving surface over a supportive dual-spring core (micro-coils on 7-zone pocket springs), strong motion isolation, breathable construction, and reinforced edges for late-pregnancy mobility. Bedbuyer, one of Australia's best-known independent mattress reviewers, rates it 3.9 out of 5.
An honest note: if you prefer a firmer feel or want the better-value option, the medium-firm Newentor Hybrid also works — and if any mattress feels too firm at the hips during pregnancy, a mattress topper adds cushioning without replacing the mattress; some of our pregnant customers have used exactly that combination.
Small things that help a lot
A pillow between your knees keeps the hips level and eases lower-back strain when side sleeping. A full-length body pillow does the same job with added bump support.
Get your head height right. Side sleeping needs a taller pillow than back sleeping — the Newentor adjustable pillow sets to four heights from 9 cm to 14 cm.
On materials: Newentor mattresses use CertiPUR-US certified foams, which are certified free from harmful substances. As with any boxed mattress, unbox it in a ventilated room and let it air — and let someone else do the lifting; the rolled mattress is heavy and lifting it is not a job for pregnancy.
When to talk to your midwife or doctor
A mattress can make sleep more comfortable, but it can't treat pregnancy conditions. Talk to your midwife, GP or obstetrician about persistent pelvic or back pain, restless legs, heartburn that disturbs sleep, snoring that starts in pregnancy, or any questions about safe sleeping positions. If you're ever advised to sleep in a specific position or elevated, follow their advice over anything you read online — including this guide.
