As your bump grows, sleeping gets harder. Back sleeping becomes uncomfortable, stomach sleeping becomes impossible, and side sleeping starts to strain your hips, back and belly. Many people end up surrounded by four or five regular pillows that slide around all night.
A pregnancy pillow replaces that pile with one shaped pillow. The best pregnancy pillow for you depends mostly on two things: how much space you have in bed, and whether you switch sides during the night.
Below are 6 pregnancy pillows we compared on Amazon, covering the three main types: U-shaped, C-shaped and small wedges. You will also find a quick guide to which shape suits which sleeper.
A quick note: this guide is about comfort. Ask your doctor or midwife about the best sleep position for your pregnancy, especially if you have back pain, swelling or other symptoms.

The 6 Best Pregnancy Pillows, Reviewed
1. Momcozy U-Shaped Pregnancy Pillow: Best Overall
A U-shaped pillow wraps around both sides of your body. You get support for your belly and back at the same time, and you can roll from one side to the other without moving the pillow. That is the main reason U-shapes are the most popular type.
The Momcozy is the most reviewed U-shaped pillow we found, with a 4.5-star average across more than 22,000 ratings. It is filled with polyester and supports your head, back, belly, hips, knees and feet. You can also fold it into different shapes for reading, watching TV or nursing.
One buyer said it stopped her waking up with a sore back after week 29, and kept her from rolling onto her back. Another used it through two pregnancies. Several non-pregnant buyers, including someone recovering from back surgery, use it as a full body pillow.
What reviewers complain about: it is heavy-ish and takes up a lot of the bed. One reviewer said it is not very comfortable before you have a bump.
✅ Pros
• Supports belly and back together
• Switch sides without moving it
• Huge review base
❌ Cons
• Takes a lot of bed space
• Fairly heavy to move
Not the right fit if: you share a full or queen bed with a partner who needs room. Look at #3 or #6.

2. QUEEN ROSE Cooling U-Shaped Pregnancy Pillow: Best Cooling
Many people run warmer during pregnancy, and a big body pillow can trap heat. The QUEEN ROSE comes with a viscose pillowcase that absorbs moisture and breathes better than a standard polyester cover.
It is 55″ long and about 31″ wide, filled with polyester. QUEEN ROSE says it replaces up to five regular pillows. It has a 4.4-star average across more than 17,500 ratings.
One reviewer tried four pregnancy pillows and kept this one, saying the others were bulky and made it hard to get up at night. Another compared it with a popular C-shaped pillow from earlier pregnancies and liked this one more.
What reviewers complain about: one side sleeper who switches often felt it was not supportive enough.
✅ Pros
• Moisture-wicking viscose cover
• Easier to get in and out of than some U-shapes
• Strong ratings
❌ Cons
• Softer support
• Still takes a lot of space
Not the right fit if: you want firm, structured support.

3. INSEN C-Shaped Pregnancy Pillow: Best C-Shape
A C-shaped pillow curls around one side of your body. It supports your head, belly or back, and knees at once, but uses less space than a U. The tradeoff is that you have to turn the pillow, or yourself, when you switch sides.
The INSEN is 58″ long, filled with long, smooth polyester fiber, and covered in soft jersey cotton. The cover is machine washable. It ships vacuum-packed, so buyers suggest kneading it and giving it time to fluff up. You can also fold it into a wedge to raise your legs.
It is rated 4.5 stars across more than 20,000 ratings. Reviewers call it soft but supportive. One buyer’s husband ordered one for himself.
What reviewers complain about: some found it skinnier than expected. A repeat buyer felt the quality had dropped.
✅ Pros
• Less bed space than a U-shape
• Soft jersey cotton cover
• Folds into a leg wedge
❌ Cons
• Must turn it to switch sides
• Slimmer than some expect
Not the right fit if: you switch sides many times a night.

4. Chilling Home 58″ U-Shaped Pregnancy Pillow: Best Budget U-Shape
If you want a full U-shape without spending much, the Chilling Home costs under $30. It is about 57″ x 28″, with a soft velvet outer cover over a polyester inner pillow.
Note the care label: the outer cover is machine washable, but the inner pillow is not. It has a 4.5-star average across 10,600+ ratings. Buyers say it helped them sleep on their side and kept working for breastfeeding after the baby arrived. A few non-pregnant side sleepers also love it.
What reviewers complain about: one buyer felt it lacked stuffing compared with a friend’s more expensive pillow. Another called it bulky.
✅ Pros
• Full U-shape for under $30
• Soft velvet cover
• Useful after pregnancy too
❌ Cons
• Inner pillow not washable
• Less fill than pricier models
Not the right fit if: you want firm, plump support.

5. Hiccapop Pregnancy Wedge Pillow: Best Wedge
Not everyone wants a giant body pillow. The Hiccapop wedge is just 15″ x 13.25″. Tuck it under your belly when you lie on your side, behind your back to stop rolling, or between your knees.
It has two sides: soft memory foam on one, firmer support foam on the other. The foam is CertiPUR-US certified and perforated for airflow. The plush velboa cover is washable.
It is rated 4.5 stars across more than 9,200 ratings. Side sleepers say it took pressure off their belly and made the third trimester easier. One reviewer said hers lasted almost two years and two pregnancies.
What reviewers complain about: it runs a little warm. One reviewer at 32 weeks felt it did not make a big difference.
✅ Pros
• Tiny, takes almost no bed space
• Soft and firm sides
• Easy to travel with
❌ Cons
• Supports one area at a time
• Plush cover can feel warm
Not the right fit if: you want back, belly and knee support all at once.

6. Boppy Side Sleeper Pregnancy Pillow: Best for Small Beds
The Boppy Side Sleeper takes a different approach. It is two small pillows joined by a stretchy center panel. One pillow sits at your belly and the other at your back, and the panel stretches as your bump grows. There are no buckles or noisy fasteners.
It is compact, so it suits smaller beds and travel. Both pillows and the jersey knit cover are machine washable. Boppy says it is tested by a third-party CPSC-accredited lab. You can read our full Boppy Side Sleeper review for more detail.
This current listing has a smaller review base, about 120 ratings and a 3.9-star average. Fans say it is the best thing they bought for pregnancy. A mom expecting her fourth baby reordered it after donating her last one.
What reviewers complain about: some found the connecting strip too stretchy to support them. One wished it were wider for later pregnancy.
✅ Pros
• Compact, leaves room for a partner
• Fully machine washable
• No fasteners
❌ Cons
• Smaller review base on this listing
• No head or knee support
Not the right fit if: you want a pillow that also supports your head and legs.

U-Shape vs C-Shape vs Wedge: Which Is Right for You?
| Shape | Best For | Watch Out For |
|---|---|---|
| U-shape | Switching sides, full back and belly support, king or queen beds | Takes up the most space, can feel hot |
| C-shape | Mostly one side, medium beds, head-to-knee support | You need to turn it when you switch sides |
| Wedge | Small beds, travel, targeted belly or back support | Supports one area only |
| Linked side pillows (Boppy) | Shared beds, belly and back support | No head or knee support |
When to Start Using a Pregnancy Pillow
There is no set week. Many people start in the second trimester, when the bump begins to make side sleeping uncomfortable. Some reviewers found a big U-shape awkward before they had a bump but loved it later. If you start early, a small wedge is an easy first step.
Tips for Sleeping on Your Side During Pregnancy
- Bend your knees and keep a pillow between them. It keeps your hips level. A full pregnancy pillow does this for you, or see our best knee pillow guide.
- Support the belly. A small pillow or wedge under the bump takes strain off your back.
- Put something behind your back. It stops you rolling onto your back during the night.
- Use the right head pillow too. Your neck still needs the right height. See our best pillow for side sleepers guide.
- Raise your upper body for heartburn. Some people find a wedge under the back helps. See our best wedge pillow guide.
FAQ: Pregnancy Pillows
What is the best type of pregnancy pillow?
For most people with enough bed space, a U-shaped pillow, because it supports both sides and you do not have to move it when you turn. C-shapes and wedges are better for smaller beds.

Whenever sleep starts to feel uncomfortable. For many people that is in the second trimester.
Can I use a pregnancy pillow after giving birth?
Yes. Many reviewers keep using them for nursing, recovery and general side sleeping.

Most have a removable washable cover. Some inner pillows are washable too, like the Boppy, while others, like the Chilling Home, are not. Check the care label.
Is a U-shaped or C-shaped pregnancy pillow better?
U-shapes are better if you switch sides often. C-shapes take up less space and work well if you mostly sleep on one side.

Yes. Several reviewers use them as full body pillows for side sleeping, back pain or recovery after surgery.
