How to Use Pregnancy Pillows: 5 Setups for Sleep, Rest and Nursing

To use a pregnancy pillow, lie on your side, place the pillow so it supports your belly and sits between your knees, and adjust it until your hips and spine feel level. A wedge goes under the belly, a C-shaped or U-shaped pillow wraps along your back and front, and a small pillow is a simple place to start. This guide explains how to use pregnancy pillows for sleep, resting on the sofa and feeding the baby afterwards, and then shows five specific setups with products that suit each one: the Momcozy Portable W-Shaped, the DONAMA memory foam wedge, the Boppy Side Sleeper, the Momcozy U-Shaped 57-inch and the Boppy Total Body.

We did not personally use these products. This guide is research-based, drawing on manufacturer details, listing information and public pregnancy sleep guidance named at the end. A pregnancy pillow is a comfort aid, not a medical device, and nothing here is a treatment or a promise of pain relief. Ask your doctor or midwife about sleep position and any pain, swelling or breathlessness.

Quick Comparison Table

The Basic Setup: How to Lie Down With a Pregnancy Pillow

1. Lie on your side with your knees bent. Many health organisations, including the American College of Obstetricians and Gynecologists, note that side sleeping may be best in the second and third trimesters, with one or both knees bent.

2. Put the pillow between your knees or along your front so that your top leg is supported level with the hip. This keeps the pelvis from twisting forward.

3. Support the belly. Use the upper curve of a C-shaped or U-shaped pillow, or slide a wedge under the bump.

4. Support the back. A U-shape or C-shape runs behind you; with a wedge, tuck a small pillow behind your lower back.

5. Check your head and neck. Use your regular pillow, because most pregnancy pillows do not support the head unless they are J-shaped or U-shaped with a head section.

6. Adjust for comfort. If your hip feels pressure, add height under the belly. If your chest feels tight, raise your upper body slightly with an extra pillow.

7. If you wake on your back, roll to your side and settle back down.

These steps work with any shape. The differences are in how much of your body each pillow supports and how much bed space it takes.

Which Setup for Which Situation

1. Momcozy Portable W-Shaped Pillow: Best Wedge to Start With

• Adjustable W-shaped wedge for back, belly and hip support
• Space-saving design marketed for travel
• Breathable removable cover
• Dimensions and fill type: not listed in the title

How to use it: lie on your side and tuck the middle of the W under your belly. Place one arm of the W behind your back and the other between your knees. Adjust the width of the W so that each point presses lightly rather than firmly.

Best for: second-trimester sleepers who want something small. Skip if: you want a pillow that wraps you from head to toe.

A W-shaped wedge is a small, flexible form that you can bend into several positions. It uses little bed space, which helps in shared beds, and it packs into a suitcase for travel. You will probably still want an extra pillow for your head.

Pros: compact; adjustable; removable cover; easy to carry. Cons: limited leg support; fewer details in the listing.

2. DONAMA Memory Foam Wedge: Best Memory-Foam Option

• Memory foam pregnancy pillow in an adjustable wedge shape
• Marketed as a cooling maternity pillow for belly, back and hips
• Travel-sized; “small pregnancy pillow”
• Dimensions and cover fabric: not listed in the title

How to use it: place the thicker end under the belly and angle the slimmer end behind the hip or lower back. Use a second pillow between the knees. If it feels too firm, fold a thin blanket over the top.

Best for: people who prefer firmer foam to polyester fibre. Skip if: you like a soft, cuddly pillow.

Memory foam shapes slowly to your body and holds its form, which some pregnant sleepers like and others find warm. The title says “cooling”, but the listing does not describe how, so treat that claim cautiously and check the description before buying. The wedge works best for the belly and lower back; it does not replace a full-body pillow.

Pros: holds its shape; small; useful on a sofa. Cons: firmer feel; limited coverage; cooling details not listed.

3. Boppy Side Sleeper Pregnancy Pillow: Best Light Pillow for Early Pregnancy

• Stay-put design for side sleepers
• Stretchy centre panel that grows with your bump
• Portable for travel and moving between rooms
• Fill type and size: not listed in the title

How to use it: slide it between your knees or under the belly, depending on where you feel pressure. The stretchy panel is meant to hold the pillow in place as you roll.

Best for: the first and early second trimester. Skip if: you need full-body support.

If you are new to pregnancy pillows, this is a gentle way to find out what helps. It is a modest design, so many people use it for a few months before moving to something larger.

Pros: light; portable; flexible panel. Cons: limited coverage; details are thin.

4. Momcozy U-Shaped 57-Inch Pillow: Best Full-Body Setup

• U-shaped, 57 inches
• Removable cover; support for back, legs, belly and hips for side sleepers
• Cooling cover version is also sold
• Fill type: not listed in the title

How to use it: lie in the middle of the U with your back against one arm and your front against the other. Rest your head on your usual pillow and your knees on the lower part of the pillow. When you roll over, the pillow stays put, so you do not need to move it.

Best for: the third trimester, when turning over becomes harder. Skip if: your bed is narrow or you share with a partner who needs space.

The U-shape gives support on both sides of your body, which many people find useful once the belly is large. Its size is a trade-off: it can take up much of a double bed. The listing says it comes with a removable cover, and a cooling cover version exists for people who feel warm at night.

Pros: supports both sides; no need to move pillows; removable cover. Cons: large; can feel warm; takes bed space.

5. Boppy Total Body Pregnancy Pillow: Best for Pregnancy and After Birth

• Contoured full-body shape for prenatal and postpartum support
• Roughly 48 to 53 inches long and 25 to 26 inches wide per retailer figures
• Polyester fibre fill; pillow and cover are listed as machine washable by the maker
• Removable cover included

How to use it: lay the pillow along your front with the upper curve under your belly and the lower curve between your knees. After birth, place it at your waist to support the arm that holds your baby while sitting.

Best for: people who want one pillow for both stages. Skip if: you dislike large pillows.

Because it is contoured and made for prenatal and postpartum use, this pillow can be used on the sofa, in bed and in a chair. Postpartum use is helpful for feeding positions, and you can combine it with a sling or wrap on days when you carry your baby. Never place the pillow near a baby in their sleep space.

Pros: multi-stage use; washable; contoured. Cons: bulky; dimensions vary by listing.

Also Consider

• SQYZ cooling wedge body pillow: a wedge-style body pillow with a removable, machine-washable cover.
• MOON PARK 57-inch U-shaped pillow: a lower-tier alternative to the Momcozy U-shape.
• Meiz 55-inch U-shaped pillow: a U-shape with a bamboo-derived rayon cover for people who run warm.

Using a Pregnancy Pillow for Other Positions

Sitting and resting

Place a wedge behind your lower back, or a C-shaped pillow behind your back and along one side. Keep your feet flat, or raised on a footstool if your ankles feel heavy.

Reading or watching TV

Tuck a body pillow under your arm and let the lower curve support your knees so you can stay semi-reclined without twisting.

Travelling

Use a portable wedge, and carry a small cover or pillowcase for hygiene.

After birth

Use a C-shaped or total-body pillow on your lap to bring the baby up to chest height when feeding. Use a pillow under your arm to reduce strain. If you plan to use a sling or wrap, practise with a doll before the baby arrives, and consult a babywearing educator for correct positioning.

Troubleshooting: When the Pillow Does Not Feel Right

Most complaints about pregnancy pillows come from set-up, not from the pillow. Use this table before you decide a pillow is wrong for you.

If a problem continues for more than a few nights, adjust one thing at a time. Changing the pillow, bedding and sleep position all at once makes it hard to know what helped.

Step-by-Step: Feeding and Resting After Birth

A pregnancy pillow that is built for postpartum use, such as the Boppy Total Body, can act as a lap support during feeding. These steps are general comfort tips, not feeding or medical advice. For help with latching, bottle-feeding technique or pain, speak with a lactation consultant, midwife or paediatric nurse.

1. Sit upright in a chair or on the sofa with your back supported by a regular pillow or a wedge.

2. Place the pillow around your waist or across your lap so the upper curve sits just below chest level.

3. Rest your elbow on the pillow so your arm does not carry the baby’s full weight.

4. Bring the baby to the pillow, not your shoulders to the baby. Keep the baby’s head, neck and body in line, with the face visible and the airways clear.

5. Keep your feet supported on the floor or a stool so your pelvis stays level.

6. When you finish, remove the pillow from the area where the baby will sleep. Adult pillows should never be left in a crib, bassinet or sleep space.

If you also carry your baby in a sling or wrap, remember that carrier positioning has its own rules. Follow the carrier maker’s instructions and a trained babywearing educator’s advice rather than adapting a pregnancy pillow technique.

A Week-by-Week Way to Introduce a Pillow

If you have never used a pregnancy pillow, a gradual introduction makes it easier to learn what you need.

• Night 1 to 3: use the pillow for the first part of the night only. Notice whether it supports the knees, the belly or the back.
• Night 4 to 7: keep the pillow all night. If you feel hot or cramped, change the position, not the pillow.
• Week 2: experiment with a wedge under the belly or a second pillow behind the back.
• Week 3 onward: if you have found a set-up that works, leave it alone. If not, decide whether a different shape would help.

This pacing helps because pregnancy discomfort changes from week to week. A pillow that felt too big in the second trimester may feel right in the third.

Keeping the Pillow Clean and Fresh

Wash removable covers every one to two weeks, more often if you sweat at night. Follow the label, and dry fully before putting the cover back on. Check the inner pillow’s care instructions; Boppy lists the Total Body pillow as machine washable, while some other pillows are spot clean only. Air the pillow in a dry room or outdoors for a few hours when the weather allows, and keep it away from pets that may chew foam or fibre. If you have allergies, a second cover lets you rotate while one is in the wash.

Pillow Placement Cheat Sheet by Body Area

Think of a pregnancy pillow as a way to fill the gaps between your body and the mattress. When you lie on your side there are four gaps: under the belly, behind the back, between the knees and under the head. Each gap can be filled by a different part of a pillow, or by a different pillow.

• Under the belly: the upper curve of a C-shaped or U-shaped pillow, or the thick end of a wedge. This keeps the weight of the bump from pulling your spine forward.
• Behind the back: the back arm of a U-shaped pillow, or a small wedge. This stops you from rolling onto your back in your sleep.
• Between the knees and ankles: the lower section of a C-shaped or U-shaped pillow. Support from knee to ankle keeps the top leg from dropping and twisting the hip.
• Under the head: your usual pillow, or the top of a J-shaped pillow. Keep your neck in line with your spine.

A single wedge can fill one or two of these gaps, a C-shape fills three, and a U-shape fills all four. That is the real reason people move up in size as pregnancy goes on: not because bigger is better, but because more gaps need filling as the belly grows. If you can sleep comfortably with one or two gaps filled, there is no need to buy a larger pillow.

Questions to Ask Yourself Before Choosing a Setup

• Where do I feel pressure when I lie on my side: hip, lower back, belly or knees?
• How much space does my bed give me after I subtract my partner’s share?
• Do I run warm at night, and would a cooling cover make a difference?
• Will I use the pillow after the baby arrives, for feeding or resting?
• Do I travel, or do I move between a bedroom and a sofa?

Your answers point to a shape. Pressure at the hip suggests a wedge and a knee pillow. Pressure in the back suggests a C-shape or a U-shape. A narrow bed suggests a wedge or a Boppy-style contoured pillow. Frequent travel suggests a portable wedge. A plan for postpartum use suggests a total-body pillow that the maker says is suitable after birth.

How We Chose

We shortlisted five pregnancy pillows that demonstrate the main shapes: two wedges, one small side-sleeper pillow, a U-shape and a contoured total-body pillow. We compared size, fill, cover and care information from manufacturer pages and retailer listings, and used public guidance on sleeping in pregnancy to explain positions. We did not personally use these products. We limited each brand to two picks, and flagged unclear details as “not listed”.

Buying Guide

Choose by shape

Wedges are compact and cheap, best for support in a single area. C-shapes and U-shapes support more of the body but take up space. Contoured total-body pillows add postpartum use.

Check the size against your bed

A 57-inch U-shaped pillow is nearly as wide as a 60-inch queen mattress. If you share a bed, measure first and leave at least 20 to 24 inches for your partner.

Fill and firmness

Polyester fibre is soft and washable. Memory foam is firmer and holds shape. Choose the one that matches how you like to sleep, and remember that fibre fill flattens with use.

Cover and care

Look for a removable, washable cover. Check whether the inner pillow can be washed. Cooling covers may help warm sleepers, but they do not change room temperature.

Return policies

Pillows are personal, so check the seller’s return policy before ordering a large one.

Common Mistakes to Avoid

• Placing the pillow under your belly only and ignoring the knees.
• Using a pillow that is too thick, which tilts the pelvis.
• Forgetting to wash the cover, which can lead to odours.
• Using a pregnancy pillow in a baby’s sleep space.

Frequently Asked Questions

How do you use a pregnancy pillow?

Lie on your side with knees bent, put the pillow between your knees or along your front, and support the belly with a wedge or the upper curve. Adjust until your hips and spine feel level.

How do you use a U-shaped pregnancy pillow?

Lie in the middle of the U with your back against one arm and your front against the other. The lower part supports your knees, and your usual pillow supports your head.

Where do you put a wedge pillow in pregnancy?

Place the wedge under your belly, with the thicker end under the bump. Add a second pillow between your knees.

Which side should I sleep on?

Health organisations generally support side sleeping in later pregnancy, with some sources favouring the left side. Ask your doctor or midwife what suits you.

Can I use a pregnancy pillow while sitting?

Yes. Put a wedge or C-shaped pillow behind your back, and keep your feet supported.

Can I use a pregnancy pillow after birth?

Some pillows, like the Boppy Total Body, are designed for postpartum use. Never place an adult pillow in a baby’s sleep area.

How long should I use a pregnancy pillow?

Use it for as long as it helps you feel comfortable, which is often from the second trimester until a few weeks after birth.

Which One Should You Buy?

Choose a wedge such as the Momcozy Portable W-Shaped or the DONAMA memory foam wedge if you want a small start. Choose the Boppy Side Sleeper for early pregnancy. Choose the Momcozy U-Shaped 57-inch for full-body support and the Boppy Total Body for a pillow you can keep using after birth.
