The Ultimate Guide to Pregnancy Pillows: How They Help, When to Use Them & Choosing the Best One

Author: Miriam Splett

You know that feeling when turning in bed becomes a full-body workout and finding any comfortable position feels impossible?

Pregnancy brings joy, anticipation… and, let’s be honest, some serious physical discomfort. From back pain and hip strain to sleepless nights and sore muscles, your body is doing a lot and your bed should support that journey, not make it harder.

That’s where a pregnancy pillow comes in.

Whether you’re googling “best pregnancy pillow” for the first time or wondering when to get one, this guide breaks down exactly what a pregnancy pillow is, why it works, when to use it, and how to find the perfect one - plus how it can support you even after birth.

What Is a Pregnancy Pillow, Really?

A pregnancy pillow is a specially designed support pillow that aligns with your body’s changing shape during pregnancy. Unlike your standard pillows, pregnancy pillows provide targeted support for your bump, hips, lower back, and legs reducing pressure and helping you find that elusive comfortable sleeping position.

There are different types, from C-shaped and U-shaped full-body pillows to more compact wedge pillows, each designed to relieve different pain points depending on how you sleep.

Why Do Pregnancy Pillows Help?

Think of a pregnancy pillow as a gentle, supportive hug that holds your body in alignment while you rest. As your bump grows, your center of gravity shifts - putting strain on your lower back, hips, knees, and neck.

Here’s how a good pregnancy pillow makes a difference:

  • Reduces back and hip pain by promoting better spinal alignment

  • Improves blood circulation by encouraging side-sleeping (especially on your left side)

  • Supports your bump and relieves pressure on muscles and ligaments

  • Eases swelling in legs and feet

  • Minimizes tossing and turning so you sleep more deeply

When Should You Start Using a Pregnancy Pillow?

There’s no hard rule, but most people start using one around week 20, when the bump becomes more pronounced and sleep gets less comfortable.

That said, if you’re feeling achy, uncomfortable, or just not sleeping well earlier than that, don’t wait. The right support early on can improve sleep quality and reduce long-term strain.

How to Use a Pregnancy Pillow (For Sleep & More)

Depending on the shape, there are a few different ways to use a pregnancy pillow:

For Side Sleepers (recommended in pregnancy):

  • Place the pillow along your body, with one leg over it and the other beneath it

  • Tuck it slightly under your bump for lift and under your lower back for support

For Back Support (while lounging or sitting):

  • Position it behind your lower back to reduce lumbar pressure

  • Use the ends as armrests while sitting upright

For Leg Elevation (to reduce swelling):

  • Lay on your side and elevate your legs slightly on the pillow to improve blood flow

And yes—it’s totally normal to use it even when you're not pregnant. These pillows are that comfy.

Can You Use a Pregnancy Pillow After Birth?

Absolutely. Your body doesn’t bounce back overnight. A pregnancy pillow can continue to:

  • Support your lower back and hips while breastfeeding or bottle-feeding

  • Help ease postpartum pressure or discomfort

  • Provide a cozy cushion for healing after a C-section

  • Become the most fought-over pillow in the house (we’ve seen it happen)

How to Choose the Best Pregnancy Pillow for You

With so many options out there, how do you know which one’s best?

Here’s what to look for:

✔️ Shape:

  • U-shaped: Great for full-body support and people who toss and turn

  • C-shaped: Supports back, hips, and bump with a little less bulk

  • Wedge: Compact option to place under belly or lower back

✔️ Materials:
Look for breathable, hypoallergenic, and easy-to-clean materials—like organic cotton or bamboo. Avoid synthetic fills that trap heat.

✔️ Adjustability:
Some pillows (like our Knot-A-Pillow) are modular and moldable, meaning you can reshape them to your needs throughout pregnancy and postpartum.

✔️ Washability:
Pregnancy and postpartum can get messy—so make sure your pillow has a removable, washable cover.

How to Clean a Pregnancy Pillow

Let’s keep it simple:

  • Removable cover? Toss it in the wash with mild detergent

  • Inner pillow? Spot clean with a damp cloth or follow manufacturer instructions

  • Pro tip: Let it air dry fully before putting the cover back on to avoid trapped moisture

Keeping your pillow fresh is key for hygiene—especially when hormones (and sweat!) are in overdrive.
