The U-shaped pregnancy pillow: sleep on your side without waking up
One pillow that holds your back, your bump and your legs at the same time. You turn over, it stays put — no more rebuilding a scaffold of pillows at three in the morning.
What wakes you is not the bump — it is the collapse

Pittsburgh sleep score in the last trimester for women given a pregnancy pillow, against 8.12 for those without one — randomised trial, 75 first-time mothers. A lower score means better sleep.
The mechanics are always the same. One pillow under the bump, a second between the knees, sometimes a third behind the back. The structure holds as long as you do not move. At the first turn, it all has to come apart and be rebuilt, half asleep, in the dark. A night in pregnancy has several of those, and each one costs you the time it takes to fall asleep again.
A U-shaped pillow solves this by its shape, not by its thickness. The two arms run down either side of you: one supports the bump and takes your bent knee, the other holds your back. When you turn over you do not leave the pillow — you move from one arm to the other. Nothing comes apart, so nothing has to be rebuilt.
Buyers say the same: out of 129 written reviews, 43 talk about sleeping comfort and sleep quality, far ahead of every other subject. It is not the material or the price that comes up first — it is getting through the night.
Three things a pregnancy pillow does that a stack of pillows cannot
It does not come apart when you move
Both arms stay put when you turn over: you move from one to the other without repositioning anything.
That is the structural difference with a stack. A single pillow has nothing holding it: it follows your body and eventually falls away. The U is one continuous volume that keeps its geometry. You do not feel the benefit as you get into bed — you feel it at the third waking of the night, the one you no longer have.
The cover goes in the machine
It comes off completely by a zip and washes on a cold cycle, as often as you need.
A pregnancy pillow is used for months, in a bed, every night. A fixed cover condemns it at the first spill. Twenty of the 129 written reviews of this model bring up the cover and how easily it comes off — a subject nobody cares about when buying, and which decides how long the thing lasts.
It will be used again after the birth
The arm of the U becomes an armrest and brings your baby to the right height while feeding.
Same object, second life. Set around your waist while seated, it supports the forearm carrying your baby — the thing that tires your shoulder on a long feed. A pregnancy lasts a few months; this pillow does not stop at the birth.
The pregnancy pillow, in your hands
It is a closed U weighing 2.9 lb (1.3 kg), filled with synthetic fiber. Neither memory foam nor microbeads: a soft filling that gives under your weight and comes back when you move. That is what lets you go from one side to the other without setting anything up again — and it is the subject that comes up most in the written reviews, 43 times out of 129.
The cover comes off completely, by a zip that runs along one arm. It goes in the machine on a cold cycle. On a pillow that stays months in a bed, that is not a comfort: it is what decides how long it lasts. Twenty buyers bring it up unprompted.
It arrives vacuum-packed, in a box of sensible size, and it needs a few hours to regain its volume — one buyer reports four to five hours. Take it out of the bag on the day it arrives if you plan to sleep with it that night: it is the one thing to know before the first night.
The stated dimensions are in the table below.

U, C or a stack: what each one holds
| Solution | Back | Bump | Legs | Holds when you turn over |
|---|---|---|---|---|
| U-shaped pillow | Yes | Yes | Yes | Yes, without repositioning |
| C-shaped pillow | One side at a time | Yes | Yes | No — you have to reposition it |
| Stack of pillows | Depends how you build it | Depends how you build it | Yes | No — the arrangement comes apart |
The U takes more room — that is its trade-off, and it is the subject 22 women out of 129 raise in their reviews. If two of you share a full-size bed, measure before choosing: we give the width it actually takes in our guide on how much bed space it takes.
During pregnancy, finding a genuinely comfortable position to sleep in is not always straightforward. A well-designed pillow like Lullacurve’s U-shaped pregnancy pillow can simply help you settle better and feel more at ease as the months go by. — Laura Mitchell, midwife · August 2026
Choosing and using your pregnancy pillow
How to settle in on the first night
Lay the pillow out flat as soon as it arrives: it ships vacuum-packed and takes a few hours to regain its volume. If you unpack it in the evening to sleep with it straight away, it will still be a little flat — no harm done, but less pleasant than on the second night.
Getting the position: lie on your side with the opening of the U pointing down. One arm goes under the bump, the other behind your back. Your upper knee folds onto the front arm, not beside it: that is what lines up your hips and takes the strain off your lower back. The curve of the U slides under your neck and replaces your head pillow — do not add one on top, or your neck will be pushed forward.
When you turn over, do not leave the pillow: pivot inside the U. The arm that was holding your back becomes the one holding your bump. That is the movement that takes two or three nights to become automatic, and it is the whole point of the shape.
After the birth, sit down and set the U around your waist, opening facing forward. The arm supports the forearm carrying your baby, at chest height. You are no longer holding that weight unsupported for the whole feed.
Care: the cover comes off by the zip and goes in the machine on a cold cycle. Air-dry it, no tumble dryer. The pillow itself does not need washing if the cover is washed regularly — just air it for a few hours now and then.

The questions we get asked
When should you start using a pregnancy pillow?
Most women start in the fourth or fifth month, when sleeping on your front stops being possible and the weight of the bump pulls on your back. Nothing stops you starting earlier — plenty use one from the first weeks simply to steady the hips.
How much room does it take in a double bed?
The stated length is 51 in (130 cm), but that measurement describes the pillow laid out flat. Once it closes around you in a sleeping position it takes up far less width — roughly half a full-size bed. Our guide on bed space gives you a way to check it at home before ordering.
Does the cover come off for washing?
Yes — it comes off completely by a zip and goes in the machine on a cold cycle. Twenty of the 129 written reviews of this model bring up the cover and how easily it comes off.
Does the pillow arrive compressed?
Yes — it ships vacuum-packed so it fits in a sensible box. It regains its shape within a few hours of being unpacked. Lay it out flat on the day it arrives if you plan to sleep with it that night: 18 women mention this in their reviews.
Can you use it after the birth?
Yes, and it is the most common use once the baby is here: the arm of the U supports your forearm and brings your baby to the right height during a feed. It is one of the two uses this shape is built for.
U-shaped, C-shaped or a stack of pillows: what is the difference?
A U supports your back and your bump at the same time, without being turned over. A C supports one side only, so it has to be repositioned every time you change position. A stack of pillows costs less but comes apart during the night, which is precisely what wakes you.
Which color should I choose?
Three colors: Herringbone Gray, Plain Gray and Blue. Herringbone Gray is by far the most ordered — it appears in 37 of the 61 customer photos — which is why it is shown first.
What if it does not suit me?
You have 30 days to change your mind. A pregnancy pillow is judged after several nights, not on unpacking it: write to us and we will refund you.
