Sleep gets harder as pregnancy goes on, and a pillow is one of the few purchases that can help. The shapes below do slightly different jobs, so the right one depends on how you sleep and how much room you have. Ask your doctor about sleeping position if you have been given specific advice.
C vs U vs wedge vs long pillow
| Shape | Supports | Bed space | Easy to turn over | Best for |
|---|---|---|---|---|
| C-shaped | Back, belly, knees | Medium | Moderate | Most side sleepers |
| U-shaped | Both sides, full body | Large | Easy | Restless sleepers, king beds |
| Wedge | One spot at a time | Very little | You move it | Early pregnancy, travel, a trial |
| Long body | Whatever you prop | Small to medium | You arrange it | Flexible use, after birth |
Which one fits you?
- Standard double bed shared with a partner: a C-shaped or long pillow.
- Wide bed and restless nights: a U-shaped pillow.
- Not sure yet, or travelling: a wedge costs little and is the lowest-risk first buy.
- Hot sleeper: pick a breathable cover whatever the shape.
The four options
Product types to search for. We have not tested them, and we are not recommending a brand.
C-shaped pregnancy pillow
Best for: Side sleepers who want back and belly support in a smaller footprint
Curves around your back and between your knees. Takes less room than a U pillow, so it fits a standard bed beside a partner.
What to look for
- Removable washable cover
- Firm, resilient filling that does not flatten
- Length that suits your height
U-shaped pregnancy pillow
Best for: People who toss and turn and want support on both sides
Wraps around the whole body, so you do not have to rearrange it when you turn over. It takes a lot of bed, and many people find it hot.
What to look for
- Breathable cover
- Enough bed width for you and a partner
- Washable cover
Pregnancy wedge pillow
Best for: Targeted support under the belly or back, and travel
A small triangular pillow you place where you need it. Cheap, easy to move around, and a good starter before you commit to a full-body one.
What to look for
- Firm foam rather than loose fibre
- Washable cover
- Size that fits under your belly
Long body pillow
Best for: Anyone who wants to hug and prop a leg without a shaped pillow
A straight, long pillow you shape yourself. The most flexible, and also useful after delivery for feeding support.
What to look for
- Length close to your height
- Removable cover
- Filling that holds its shape
What to check before buying
- A removable cover you can wash. This one matters more than the shape.
- Filling that springs back when you press it. Cheap fibre can flatten within weeks.
- The return policy. Pillow comfort is personal and you will not know until you sleep on it.
