Sleeping in pregnancy? Easier said than done. You shift, stack pillows, adjust again—then the baby delivers a swift kick to the ribs.
Growing a tiny human throws everything off balance, especially your sleep. That’s where a pregnancy pillow can help. But how and when to use a pregnancy pillow isn’t always obvious—especially with so many shapes, styles, and opinions out there.
Key Takeaways
- Why is a pregnancy pillow necessary? Because sleep gets harder as your body changes. Most people benefit from one between weeks 12 and 20, or as soon as comfort becomes a struggle.
- Pregnancy pillows come in all shapes—U, C, wedge, modular—and each supports different pressure points. Knowing how to use the right one can make side sleeping, back pain, and bump support a whole lot easier.
- These pillows aren’t just for sleeping—they help with lounging, recovery, and even nursing. Learn how to clean, store, and reuse your pregnancy pillow to get the most out of it during and after pregnancy.
Pregnancy pillows aren’t just oversized cushions. The right one supports your belly, eases hip pressure, and keeps your spine aligned—so sleep actually feels possible.
The Sleep Health Foundation points out that “women have less deep sleep and wake more often during pregnancy,” making quality rest a bigger deal than ever.
In this guide, we’ll explain when to start using one pregnancy pillow, how to sleep with a U shaped pregnancy pillow, and what to do with it once baby’s here.

How to Use Each Type of Pregnancy Pillow
Let’s be honest—pregnancy pillows come in all shapes and sizes, and figuring out how to use them can feel like decoding IKEA instructions.
So, let’s simplify it. Here’s how each type actually works and how to use a pregnancy pillow to get the support (and sleep) you need.
U-Shaped Pregnancy Pillow
✅ Great for side sleepers and frequent position switchers
Big, supportive, and shaped like a hug that never lets go. A U shaped pregnancy pillow wraps around both sides of your body, giving support to your back, bump, hips, and even your head.
How to sleep with a U shaped pregnancy pillow:
1️⃣ Slide into the centre of the pillow so both sides curl around you.
2️⃣ Tuck one arm under the side of the pillow, and rest the other on top.
3️⃣ Pull the bottom curve between your knees.
4️⃣ Adjust sides to support your back or belly as needed.
5️⃣ Settle in and sleep soundly.
C-Shaped Pregnancy Pillow
✅ Ideal if you want back support without being fully surrounded
A little sleeker but still plenty supportive. C shaped pregnancy pillows cradle your body from behind and under the belly, following your natural curves.
How to use a C shaped pregnancy pillow:
1️⃣ Rest your head on the top curve.
2️⃣ Press your back into the long edge for support.
3️⃣ Hook your top leg over the bottom end.
4️⃣ Let the pillow take the pressure off your hips and spine.
5️⃣ Adjust as your bump grows to stay comfy.
Wedge Pregnancy Pillow
✅ Perfect for targeted support and small-space sleepers
Small but mighty. A pregnancy wedge pillow is great for targeted support—under your bump, behind your back, or even between your knees.
How to use a pregnancy wedge pillow:
1️⃣ Slide it under your belly when lying on your side.
2️⃣ Use it behind your back to stay in place.
3️⃣ Place it between your knees to ease hip strain.
4️⃣ Prop up your feet or ankles to reduce swelling.
5️⃣ Keep it handy—it’s easy to reposition anytime.
Full-Length/Body Pillow
✅ Best for those who like to hug and stretch
Think of it as a giant cuddle buddy. These long, straight pillows are easy to adjust but don’t offer the structured support of the U or C shapes.
How to use a pregnancy pillow for back pain or general comfort:
1️⃣ Lie on your side, facing the pillow.
2️⃣ Hug it with both arms.
3️⃣ Slide one leg over the pillow.
4️⃣ Let the pillow align your hips and support your bump.
5️⃣ Use it to ease lower back strain and help stay on your side.
Modular or Adjustable Pregnancy Pillow
✅ Ideal for customisers and those needing flexible support
Not every pregnancy pillow sticks to a fixed shape. Some come in modular designs, featuring a main body pillow and separate support pieces that you can move and adjust as needed.
How does this type of pregnancy pillow work?
1️⃣ Arrange the pieces to suit your current sleeping position.
2️⃣ Use all components together for full-body comfort.
3️⃣ Separate and move pieces to focus on pressure points.
4️⃣ Position supports under your belly, behind your back, or between your knees.

When Do You Need a Pregnancy Pillow?
There’s no exact week you have to start using a pregnancy pillow. Some people grab one in the early weeks for extra comfort, while others hold off until sleep turns into a nightly game of trial and error.
The real answer? Use one as soon as your body starts asking for backup.
Here are five signs it might be time to bring one into bed:
- You’re tossing and turning all night, unable to find that “just right” spot.
- Your back, hips, or pelvis ache by morning, even if you felt fine going to bed.
- Side sleeping feels awkward, especially without support under your belly or knees.
- You’re building pillow forts, trying to prop up different parts of your body.
- You’re waking up more tired than rested, despite getting enough hours in bed.
Most people start using a pregnancy pillow between weeks 12 and 20, when the bump becomes more noticeable and weight shifts start to strain your back and hips.
And it’s not just for sleeping. Many use theirs on the couch, during naps, or even while working from bed. Whenever your comfort starts slipping, that’s your cue.
Benefits of Using a Pregnancy Pillow
Let’s be real—pregnancy pillows aren’t just nice to have. When your bump’s growing, your back’s aching, and your regular pillow feels like it’s lost the plot, having proper support isn’t a bonus—it’s a game plan for better sleep.
Here’s what a good pregnancy pillow can actually do for you:
Eases pressure on your belly and hips
As your body changes, the weight on your hips and lower back increases—especially if you’re sleeping on your side. A pregnancy pillow cushions those pressure points and helps keep everything more aligned.
Supports better spinal alignment
Whether it’s a full-body pillow or a simple wedge, the extra support helps your spine stay in a more natural position. Less strain on your lower back = fewer aches when you wake up.
Helps reduce swelling
Putting a pillow between your legs or under your ankles can improve circulation, which may ease puffiness in your feet or hands—especially in the third trimester.
Encourages side sleeping
A good pregnancy pillow helps you stay on your side—comfortably and consistently. This isn’t just about support. According to NSW Health, “women who go to sleep on their side from 28 weeks of pregnancy can halve the risk of stillbirth, compared to going to sleep on their back.“
Staying off your back helps maintain healthy blood flow to your baby, and the right pillow makes it easier to keep that position through the night.
Improves overall sleep quality
With fewer interruptions, better posture, and less tossing and turning, you’re more likely to get the kind of sleep that actually feels like sleep.
And honestly, once your baby arrives, you may not want to give it up. Many new parents keep using their pregnancy pillow for nursing, lounging, or just getting through the night feeds in one piece.
How to Choose a Pregnancy Pillow
With so many shapes, fillings, and sizes out there, choosing a pregnancy pillow can feel a bit like shopping for the right mattress—overwhelming.
Here’s what to look out for when narrowing down your options:
Sleep Position Matters
Your usual sleep habits will shape (literally) what kind of pillow works for you.
- Side sleepers: U-shaped, C-shaped, and body pillows offer excellent support from every angle.
- Back sleepers transitioning to side: Look for U-shaped or modular pillows to gently keep you on your side.
Choose the Right Shape
Wondering which pregnancy pillow shape is best? That depends on your sleep style, support needs, and how much space you’ve got to stretch out. Each shape offers something different—and the best one is the one that works for you.
- U-shaped: Full support front and back. Great for restless sleepers.
- C-shaped: Good balance of support without taking over the bed.
- Wedge: Small, portable, and perfect for targeted relief.
- Body pillow: Best for hugging and leg support, but not as structured.
- Modular: Customisable and versatile—ideal for shifting comfort needs.
Material Makes a Difference
What’s inside (and outside) your pillow affects breathability, softness, and how hot you get at night.
- Memory foam: Offers great contouring but can retain heat.
- Polyfill: Softer, lighter, and often more breathable.
- Cooling fabrics or gel layers: Help regulate temperature—ideal for hot sleepers.
- Organic or hypoallergenic covers: Gentle on sensitive skin.
Think About Where You Need Support
If you’re already feeling certain aches and pains, focus on pillows that target those areas.
- Back pain: U-shape or modular pillows with lumbar support.
- Hips and knees: Anything that fits between your legs helps align your spine.
- Belly support: Wedge and C-shaped pillows lift your bump gently and comfortably.
Consider Bed Size and Sleep Setup
If you’re sharing your bed, you might not want a pillow the size of a small sofa.
Tight on space? Go for a wedge pillow or slim C-shape.
Room to stretch? Embrace the U-shape or full-length pillow option.
Don’t Forget Washability
Pregnancy comes with a fair bit of sweat, spills, and general mess. Make life easier.
Look for pillows with removable, washable covers. Bonus if the fabric is moisture-wicking or breathable.
Special Features
Some pregnancy pillows come with extras that can make a real difference—especially as your body changes from week to week.
- Cooling covers help regulate your temperature (a lifesaver if you run hot).
- Adjustable fill lets you add or remove stuffing to suit your firmness preference.
- Modular designs come with detachable or repositionable parts, so you can tailor the shape to your needs.
If your comfort setup changes often—or you just like more control—these are well worth considering.
Making the Most of Your Pregnancy Pillow
Your pregnancy pillow isn’t just for bedtime. Here are a few extra ways to get the most out of it—before, during, and even after pregnancy:
Use it beyond the bed
✅ Prop yourself up while reading or watching TV.
✅ Support your back during long sits or working from the couch.
✅ Transition it into a nursing pillow post-baby.
Store it smart
Wondering how to store a pregnancy pillow? Roll or fold it into a cotton bag, vacuum storage pouch, or under-bed organiser.
Avoid plastic if you’re storing long term—fabric bags allow it to breathe.
Keep it clean
Most come with removable covers—if you’re wondering how to clean a pregnancy pillow, just unzip the cover and toss it in the wash.
For non-washable inserts, air them out occasionally to keep things fresh.
Give it a second life
Not sure what to do with an old pregnancy pillow? If it’s still in good shape, pass it on to a mum-to-be or donate it.
A bit worn? Use it as extra support while lounging or during postpartum recovery.
The right pregnancy pillow can change everything—from the way you sleep to the way you feel when you wake up. Whether you need full-body support or something compact and cooling, Ecosa has options to match your body and your bedtime routine.
