A growing bump can make an ordinary night’s sleep feel surprisingly complicated. The position that was comfortable last month may now leave your hips aching, your lower back tense or your shoulders feeling unsupported. Maternity pillows are designed to make those small but meaningful adjustments easier, giving your body a softer, more supported place to rest as pregnancy progresses.
The right pillow will not guarantee eight uninterrupted hours - frequent loo trips, heartburn and a busy mind can still get in the way. But good support can reduce the pressure points that make it difficult to settle, helping you find a position that feels more comfortable night after night.
Why maternity pillows can make a difference
As your body changes, so does the way you sleep. The extra weight at the front of your body can pull on the lower back, while side sleeping may place more pressure on your hips and knees. Many pregnant people also find that their usual pillow no longer gives their head and neck the support they need.
A maternity pillow works by filling the gaps between your body and the mattress. When placed between the knees, behind the back or under the bump, it can help keep your spine in a more comfortable, neutral position. This is particularly useful when sleeping on your side, a position commonly recommended later in pregnancy.
Comfort is personal, though. Some people want a large, cocooning pillow that supports several areas at once. Others sleep better with a smaller pillow they can move around easily. The best choice is the one that suits your body, your bed and the way you naturally settle down to sleep.
Choosing between maternity pillow shapes
The shape of a maternity pillow changes how it feels in bed and what it supports. Before choosing, think about whether your main concern is your bump, your back, your hips or simply getting comfortable on your side.
Full-length body pillows
A long body pillow is a straightforward, versatile option. You can hug it at the front, rest a knee over it and tuck part of it beneath your bump. This helps relieve pressure through the hips while giving your arms somewhere comfortable to rest.
Full-length pillows are often a good choice for those who like to turn from one side to the other during the night. They do not surround the body, so they are easier to reposition than larger designs. They can also remain useful after pregnancy as an extra support pillow for reading, lounging or feeding.
U-shaped maternity pillows
A U-shaped design supports both the front and back of the body at the same time. One side can sit beneath the bump and between the knees, while the other supports your back. If you wake often after rolling on to your back, having that gentle support behind you may make it easier to return to a comfortable side-sleeping position.
The trade-off is size. U-shaped maternity pillows take up a fair amount of room, especially in a double bed. They are ideal if you prefer a wrapped, secure feeling and have enough space to accommodate one comfortably.
C-shaped maternity pillows
C-shaped pillows curve around the body, usually supporting the head, bump and knees in one shape. They offer a cosy feel without quite the same bulk as a U-shaped design, making them a practical middle ground for many bedrooms.
Depending on how you position it, the lower section can sit between your knees or behind your legs. It may take a few nights to find the right arrangement, but this flexibility is part of the appeal.
Wedge and compact support pillows
A smaller wedge is designed for targeted support. It can sit under the bump, behind the back or between the knees, and it is easy to take with you if you are travelling or staying away from home.
Compact maternity pillows suit anyone who does not enjoy the feeling of a full-body pillow, or who shares a smaller bed. They are less likely to support your whole body in one go, so you may prefer to pair one with your usual head pillow or an additional cushion.
What filling and cover should you choose?
Shape matters, but the filling affects how a pillow performs over time. A pillow that feels wonderfully soft at first can become less helpful if it quickly flattens, while one that is very firm may feel uncomfortable against tender hips or ribs.
Hollowfibre fillings tend to feel light, soft and familiar. They are often a sensible everyday choice, particularly where a washable pillow is a priority. Look for a filling with enough loft to cushion the knees and support the bump without collapsing under your weight.
Memory foam gives a more moulded, pressure-relieving feel and can be especially helpful for targeted support. It does, however, feel firmer than fibre and may retain more warmth. If you often sleep hot, a breathable cover and lighter bedding can make a noticeable difference.
Natural fillings and breathable cotton covers can appeal if temperature regulation is high on your list. Whatever filling you choose, a removable, washable cover is worth having. Pregnancy can bring night sweats, spills and plenty of everyday mess, so easy care adds real value rather than being an afterthought.
How to use a maternity pillow for side sleeping
Start by lying on your side with the pillow running along the front of your body. Rest your upper arm over the pillow and place the lower section between your knees. Keeping the knees slightly apart can reduce the pull through your hips and lower back.
If your bump needs more support, gently tuck part of the pillow underneath it rather than forcing the pillow into a position that feels too high. The aim is light support, not pressure. A wedge can be particularly useful here because it stays close to the body without taking up much room.
For back support, position a section of the pillow behind you. It should feel like a reassuring cushion rather than something that pushes you forward. Small changes make a difference, so adjust the height, angle and placement until your shoulders, hips and knees can relax.
Do not forget your head pillow. A maternity pillow supports the rest of the body, but your neck still needs to stay aligned. If your usual pillow is too flat or too high, you may wake with neck stiffness even when your bump and hips feel well supported.
Making your sleep space more comfortable
A maternity pillow works best as part of a comfortable sleep set-up. Breathable sheets, a supportive mattress and bedding that lets you regulate your temperature all contribute to a more restful night. If you are overheating, lighter layers are often more useful than simply adding another pillow.
It can also help to keep the bedroom routine simple. A glass of water, a clear route to the bathroom and a pillow arranged before you get into bed can make those middle-of-the-night wake-ups less disruptive. If heartburn is troubling you, raising your upper body slightly with suitable pillow support may feel more comfortable, although it is always sensible to seek advice from your midwife or GP about persistent symptoms.
There is no need to buy the biggest maternity pillow simply because it looks the most supportive. Consider the size of your bed, whether you share it and how much room you need to move freely. A compact wedge may be perfect for one person, while another will value the all-round support of a U-shaped design.
Looking after your pillow
Check the care label before washing, as this varies by filling and construction. Removable covers should be washed regularly, while the pillow itself may only need airing or occasional cleaning. Using a spare cover can be handy when one is in the wash.
Give fibre-filled pillows a gentle shake to redistribute the filling and help them keep their shape. If a pillow no longer springs back, feels lumpy or no longer provides the support you bought it for, it may be time to replace it. Comfort should not mean making do with a pillow that has lost its purpose.
A well-chosen maternity pillow can become one of the most useful comforts in the bedroom: there when your hips need cushioning, your bump needs a little lift or you simply want a more settled place to rest. Give yourself a few nights to adjust, move it around without overthinking it, and keep the position that lets your body relax most naturally.
