1. Origin Hybrid (best mattress for pregnancy overall)

Side sleeping through pregnancy asks two things of a mattress at once: cushion the shoulder and hip that now carry your weight, but do not let the middle sag and pull your spine out of line. The Origin Hybrid does both. Its HexaGrid comfort layer flexes under the shoulder and hip to relieve pressure, while 7-zone ErgoCoil pocket springs stay firmer under the waist and lower back to keep you level as the bump grows.

The feel is a true medium-firm, which sounds firm for a soft-sleeping topic but is deliberate: it gives the cushioning of the HexaGrid without the sinking, hammocked feeling that makes it hard to roll over in later pregnancy. It also sleeps cool, and the removable, machine-washable TENCEL cover is genuinely useful in the newborn months. From $503, with a 120-night trial and a 15-year warranty, it is built to serve well past the birth.

If you already know you want a plush, sink-in feel, the medium-soft Emma Comfort further down may suit you better. But as the one bed that balances real pressure relief with reassuring support, and keeps that support as your body changes, the Origin is the safest pick for most expecting side sleepers.

Pick if...

You want dependable pressure relief for side sleeping without losing the spinal support that keeps you comfortable as your bump grows.

2. Emma Comfort (best cushioning pick)

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

When the advice is to sleep on your side and your hips ache by morning, a softer, more cushioned surface can be a relief. The Emma Comfort is the plushest pick here, a medium-soft feel around 6.7/10 built from three foam comfort layers over pocket springs. Shoulders and hips sink in and are cradled rather than propped up, which is exactly what many expecting side sleepers are chasing.

It is also outstanding for the reality of pregnancy sleep: broken. The foam-over-spring build isolates motion so well that a partner shifting, or your own repeated trips up in the night, are far less likely to jolt you fully awake. Add Australia’s most-awarded mattress pedigree, thousands of five-star owner ratings, and the longest trial on this list at 150 nights, and there is plenty of time to be sure it suits you.

The trade-off is the softness itself. At 6.7/10 it gives less pushback than the Origin or Newentor, so if you find you sink too far or struggle to turn over as the bump grows, a firmer hybrid may serve you better late in pregnancy. Because Emma discounts hard and the price swings with each sale, check the current deal rather than assume a set number.

Pick if...

You want the softest, most cushioned pressure relief and top-tier motion isolation for the broken sleep pregnancy brings.

3. Newentor Hybrid (best value pick)

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

Pregnancy is an expensive time, and the Newentor Hybrid proves you do not need to spend big for proper side-sleeping support. Its 7-zone pocket-spring core runs softer under the shoulder and firmer under the waist, so the shoulder can settle in while the lower back stays supported. A queen regularly sells under $600, leaving budget for the cot and the pram.

It is not a bare-bones bed either. A gel-infused memory foam layer takes the edge off the surface, the bamboo-charcoal cover helps you sleep cool when pregnancy runs you hot, and the foams are CertiPUR-US certified under an OEKO-TEX Standard 100 cover, which is reassuring detail at any price. A 120-night trial and 10-year warranty back it up.

The feel is medium-firm (about 6/10), a touch firmer than a dedicated soft sleeper might pick, and the cover does not unzip for washing, so pair it with a protector. For the pressure relief and support you get for the money, though, it is the standout value choice for an expecting side sleeper.

Pick if...

You want genuine zoned spring support for side sleeping without stretching the budget the rest of the baby prep needs.

4. Ecosa Mattress (best adjustable pick)

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

The one certainty of pregnancy is that your body keeps changing, and so does what feels comfortable. The Ecosa answers that better than any bed here because it is really three mattresses in one: unzip the cover and reorder the internal layers to switch between Plush, Medium and Firm. Craving a softer hip cradle in the second trimester, then more support as the bump gets heavy? You can change it at home without buying a new bed.

Underneath the flexibility is a well-made all-foam bed. A breathable contour foam supports a little like latex while sleeping cooler, the cover is removable and washable, and a waterproof protector comes in the box, handy for the newborn stage. The 15-year warranty is among the longest here, so it is a long-term buy rather than a pregnancy-only stopgap.

It is the priciest pick on the list, with a queen around $1,240, and being all-foam it lacks the springy responsiveness that makes turning over easy on the hybrids above. But if not knowing which firmness will suit you is the thing holding you back, the ability to dial it in at home is worth the stretch.

Pick if...

You expect your comfort to shift through the trimesters and want to adjust the feel between Plush, Medium and Firm at home.

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 earns a place on any list, and plenty of expecting parents search for it by name. The Koala is built on Kloudcell foam under a soft TENCEL cover, with excellent motion isolation that helps when night waking is constant, a flippable comfort layer that switches between medium-firm and firm, a 120-night trial and famously fast metro delivery.

For pregnancy side sleeping specifically, though, it lands last. Both of its flippable settings run on the firmer side, so there is no genuinely plush option to cradle a sore hip and shoulder, and being all-foam it lacks the zoned spring support the hybrids above use to keep the waist level as the bump grows. From $890 it also costs more than the value picks. It is a good, well-supported mattress and a safe brand; for an expecting side sleeper, the picks above simply cushion pressure points better.

How we choose mattresses for pregnancy

There is no lab-coat theatre here, just the same process applied to every mattress whether the brand works with us or not. This is a comfort guide, not medical advice, so for pregnancy specifically we:

• Prioritised side-sleeping pressure relief — a feel that cushions the shoulder and hip without letting the waist collapse, since side sleeping is the position most expecting parents settle into.
• Checked spinal support — zoned springs or dense support foam that keeps the lower back level as the bump adds load, rather than a bed that hammocks in the middle.
• Weighted motion isolation and cooling — because pregnancy sleep is broken and often hot, and a bed that muffles movement and breathes helps you get back to sleep.
• Read the fine print — trial length and warranty, so you have time to be sure and a bed that lasts well past the newborn months.
• Confirmed live pricing — every price was checked on the brand’s own page in July 2026, and where a brand discounts constantly we tell you to check the current sale.

Sleep Society may earn a commission if you buy through links on this page. That never changes the order: the most reassuring all-round pick leads and Koala sits last with no link at all. And for any pain, positioning or high-risk concern, please talk to your midwife, obstetrician or GP rather than a mattress guide.
