A pregnancy pillow is designed to support your growing body while you sleep. It helps relieve pressure on your hips, back, bump and pelvis, making side sleeping more comfortable and helping many mums get a better night's sleep.
As a mum of two, I know just how quickly sleep can become one of the hardest parts of pregnancy. During both of my pregnancies, a pregnancy pillow became one of the few things that genuinely helped me stay comfortable at night. It was that experience that eventually inspired me to design the Belly Bliss Pregnancy Pillow.

Wondering What a Pregnancy Pillow Actually Does?
If you've been researching ways to sleep more comfortably during pregnancy, you've probably come across pregnancy pillows everywhere.
But if you're asking yourself, "What does a pregnancy pillow do?", you're not alone.
At first glance, it can seem like just another pillow. But once your bump starts growing, your hips ache, and side sleeping becomes your new normal, you quickly realise why so many mums say a pregnancy pillow was one of their best pregnancy purchases.
By the time your bump starts growing, you'll probably find that the sleeping position you've always loved just doesn't feel as comfortable anymore. That's where a pregnancy pillow can make a real difference. Rather than simply being another pillow on the bed, it's designed to support your changing body and take pressure off the areas working the hardest.
Why Sleep Gets Harder During Pregnancy
Pregnancy places new demands on your body every week.
During my second pregnancy, rolling over in bed became one of the hardest parts of the night. I'd wake every time I changed sides because of the pressure through my hips and pelvis. Once I started sleeping with proper support between my knees, under my bump and behind my back, I noticed I wasn't waking nearly as often.
As your baby grows, you may experience:
- Hip pain
- Pelvic discomfort
- Lower back pain
- Pressure on your belly
- Frequent waking during the night
- Difficulty finding a comfortable sleeping position
Many women are also encouraged to start side sleeping during pregnancy, particularly from the second trimester onwards.
Health New Zealand recommends sleeping on your side from around 28 weeks of pregnancy, as side sleeping supports healthy blood flow for both you and your baby. While side sleeping is recommended, it isn't always comfortable without support.
That's where a pregnancy pillow comes in.

What Does a Pregnancy Pillow Do?
A pregnancy pillow is designed to support your body in multiple places at once.
Rather than using several standard pillows that move around during the night, a pregnancy pillow provides targeted support where you need it most.
Supports Your Growing Bump
As your belly grows, the weight can place strain on your back, hips, and abdominal muscles.Ā A pregnancy pillow helps support the bump, reducing pressure and making side sleeping feel much more comfortable.
Helps Keep Your Spine Aligned
When your hips, knees, and back are properly supported, your spine stays in a more natural position.
This can help reduce:
- Lower back pain
- Hip discomfort
- Morning stiffness
Reduces Pressure on Hips and Pelvis
Pregnancy hormones naturally loosen your joints and ligaments in preparation for birth.Ā While this is completely normal, it can also lead to discomfort around the hips and pelvis.Ā Supporting your knees and legs while sleeping helps keep your hips aligned and can significantly reduce overnight pain.
Encourages Comfortable Side Sleeping
Many maternity care providers recommend side sleeping during pregnancy, especially later in pregnancy.Ā A pregnancy pillow helps make side sleeping feel more natural by supporting your body and helping prevent uncomfortable rolling.

A pregnancy pillow isn't designed to make pregnancy disappear, it simply helps support the areas of your body working the hardest. By keeping your body in better alignment while you sleep, many mums find they wake feeling less sore and more rested.
Why the Belly Bliss Pregnancy Pillow Is Different
Not all pregnancy pillows are created equal. One of the most common frustrations I hear from mums is that traditional pregnancy pillows can feel bulky, restrictive, or difficult to adjust.
After using pregnancy pillows myself, I realised they all seemed to have the same problem. They were often bulky, difficult to reposition, and once baby arrived they were pushed into the cupboard.
When I started Belly Bliss, I wanted to design something different.
I chose a modular three piece design because I wanted one pillow that could adapt as your body changed throughout pregnancy, then continue being useful after birth.
I love buying products that last beyond one stage of life, and I wanted our pregnancy pillow to do exactly that.
This flexibility is one of the reasons it has become a favourite among New Zealand mums.

A Pregnancy Pillow Can Help Beyond Sleep
Most people think pregnancy pillows are only for sleeping.Ā In reality, many mums continue using theirs long after baby arrives.
Breastfeeding Support
A pregnancy pillow can provide additional support during feeding sessions by helping position baby comfortably and reducing strain on your arms, shoulders, and back.

Postpartum Recovery
Many women use their pregnancy pillow during postpartum recovery for:
- Extra back support
- Comfortable sitting positions
- Resting after birth
- Feeding support
This makes a pregnancy pillow one of the few pregnancy products that continues to be useful well into motherhood.
Do You Really Need a Pregnancy Pillow?
Technically, no, you can absolutely use regular pillows.
In fact, that's exactly what I tried during both of my pregnancies. Every night I'd build a little nest of pillows around me, only to wake up with them scattered across the bed a few hours later.
A pregnancy pillow simply keeps everything where it needs to be, so you're not constantly readjusting throughout the night. If you're waking sore, struggling to get comfortable, or finding it hard to stay asleep, it can make a huge difference.
Me breastfeeding my son using the Belly Bliss Pregnancy Pillow.
One of my favourite things about the modular design is that it doesn't stop being useful once your baby arrives. After pregnancy, I simply reconfigured the pillow and used it almost every day while breastfeeding. It helped support my son and took the pressure off my shoulders, neck and arms during those long newborn feeds.
FAQs About Pregnancy Pillows
When should I start using a pregnancy pillow?
There's no perfect time. Some mums start in the first trimester, while others don't need one until much later. Personally, I started around 16 weeks because my sleep was already becoming uncomfortable, and I'm so glad I did. The earlier you introduce one, the more natural it feels by the time your bump is at its biggest.
Can a pregnancy pillow help with hip pain?
It certainly can. One of the biggest benefits is the support it provides between your knees, which helps keep your hips aligned while you sleep. During my pregnancies, this made rolling over and waking up in the morning much more comfortable.
Do pregnancy pillows help with side sleeping?
Absolutely. They're specifically designed to make side sleeping more comfortable and sustainable.
Can I use a pregnancy pillow after birth?
Yes. Many women continue using their pillow for breastfeeding, bottle feeding, and postpartum recovery.
Is a pregnancy pillow worth it?
For many mums, improved sleep, reduced discomfort, and continued postpartum use make it one of the most worthwhile pregnancy purchases.
Final Thoughts
Pregnancy pillows aren't just about comfort, they're about supporting your body through one of the biggest physical changes you'll ever experience.
By helping support your bump, back, hips, and pelvis, a pregnancy pillow can make side sleeping easier, improve sleep quality, and reduce common pregnancy aches and pains.
Key things to remember:
- Pregnancy pillows support your changing body throughout pregnancy.
- They help make side sleeping more comfortable and sustainable.
- Proper support can reduce pressure on your hips, back, and pelvis.
- Many pregnancy pillows continue to be useful after birth.
Looking back, buying a pregnancy pillow was one of the best investments I made during pregnancy. Better sleep doesn't just help you feel more comfortable, it helps you cope with everything else pregnancy throws at you.
If you're finding it harder to get comfortable at night, don't wait until you're exhausted. A little extra support can make a world of difference.
A Note From Elle
I created Belly Bliss after experiencing just how difficult sleep can become during pregnancy. Every article I write is based on both my own experience as a mum of two and current pregnancy guidance, because my goal is to help other mums feel more comfortable and better supported throughout pregnancy and beyond.
If you're still deciding whether a pregnancy pillow is right for you, I hope this guide has helped you feel a little more confident in making the choice that's best for you.
