5 Proven Benefits of Using a Body Pillow During Pregnancy
Sleep in pregnancy gets harder by the trimester. A growing bump rules out stomach sleeping. Back sleeping becomes uncomfortable and is advised against from the second trimester onwards. That leaves expectant mothers with side sleeping as the recommended position, particularly on the left side, where it supports circulation and blood flow to the baby. The trouble is that side sleeping without proper support generates its own problems: hip pressure, lower back strain, and shoulder ache that can wake you several times a night.
A body pillow is the most useful single object for solving this. Not a regular pillow propped between the knees, which usually shifts during the night, but a long curved pillow designed to support hips, bump, knees, and head simultaneously.
Are Body Pillows Effective in Pregnancy?
A randomised controlled trial published in BMC Pregnancy and Childbirth examined the effect of pregnancy pillow use on sleep quality and back pain in pregnant women. The intervention group, which used a pregnancy pillow nightly, showed statistically significant improvements in sleep quality scores and reductions in lower back pain compared with the control group, who used standard pillows.
Put simply, the right pillow geometry - supporting multiple pressure points at once - does meaningful work that regular pillows can't match. The Simba Body Pillow with Stratos® Cool Touch Tech is designed precisely for this: a long curved shape that supports both hips and bump, with cooling tech for the night sweats that often accompany pregnancy.
Benefit 1: Hip and Pelvic Support
The growing weight of the bump pulls the pelvis forward and down, which puts pressure on the hip joint of whichever side you're lying on. Without support, the upper leg slides forward over the lower leg, rotating the pelvis and twisting the lower spine. A body pillow held between the knees keeps the legs stacked, the pelvis neutral, and the hip joint properly aligned.
Benefit 2: Bump Support
In the second and third trimesters, the bump's weight pulls the abdomen downward when you're lying on your side, which strains the round ligaments and the lower back. A body pillow positioned under the bump takes that weight, reducing the pulling sensation and the discomfort it causes.
The curved shape of a proper body pillow is what makes this work. A straight pillow can support either the bump or the knees but not both at the right angle. The curve lets one piece of bedding hold the bump up and the knees apart at the same time.
Benefit 3: Cooler Sleep Through Pregnancy Heat
Pregnancy raises core body temperature, particularly in the third trimester, and overheating is one of the most common reasons pregnant women wake during the night. A body pillow that adds insulation without cooling can make the problem worse.
Simba's Body Pillow uses Stratos® thermoregulating technology, and the fill is Simba Renew™ (recycled PET fibres combed into airy layers), designed for airflow rather than heat trapping. For a pregnant woman who's already running warm, that thermal profile matters. A regular cotton-filled body pillow can act like an additional duvet wrapped around the body, which is the opposite of what's wanted.
Benefit 4: Reduced Tossing and Turning
The cumulative effect of better hip, bump, and knee positioning is that the body doesn't need to keep readjusting through the night. Each adjustment costs sleep; the brief wakings that follow a position change can fragment sleep architecture and reduce restorative deep sleep.
The Simba Body Pillow's shape is designed to hold position, which means once it's properly placed, it tends to stay there. The recycled PET fibre fill also retains shape better than down or polyester ball fill, both of which compress and clump over the course of a night.
Benefit 5: Continued Use After the Baby Arrives
A body pillow isn't a single-trimester purchase. It remains useful through:
- Postpartum recovery, particularly after a c-section, where the pillow can support the abdomen during sleep and prop the body up for breastfeeding
- Nursing, where the curve supports baby's weight at the breast and reduces strain on the back and shoulders
- Returning to regular side sleeping, where the pillow continues to support hip alignment for anyone who finds side sleeping puts pressure on the hip joint
The Body Pillow's Stratos® cool-touch technology and machine-washable cover (40°C delicates) makes the practical side manageable through what's often a messy period of life.
How to Position a Body Pillow in Pregnancy
Position |
What it supports |
When it helps |
|---|---|---|
|
Bump, hips, knees, ankles |
Standard side sleeping, all trimesters |
|
|
Tucked behind the back (curve facing forward) |
Lower back, prevents rolling onto back |
Late pregnancy when back sleeping must be avoided |
|
Curve under the bump and between the knees |
Bump weight, hip alignment |
Heaviest part of the third trimester |
Simba's recommended position for maternity use is the first one in the table: hug one end, wrap legs around the other, top leg bent slightly.
Final Thoughts
A body pillow does several jobs at once that a regular pillow can't, supporting the hips, bump, and knees, encouraging side sleeping, and reducing the position changes that fragment pregnancy sleep. Combined with a cooling technology for the temperature rise that comes with pregnancy, the right pillow can meaningfully reduce night waking through the second and third trimesters. It continues to earn its place after the baby arrives, which makes it one of the better-value pieces of bedding to buy during pregnancy.
FAQs
Most pregnant women find it useful from around the second trimester onwards, when stomach sleeping is no longer possible and the bump starts to add weight. Some begin earlier; it's a question of when side sleeping starts to feel uncomfortable without support.
Yes, with the standard caveat that adult bedding should be kept away from a baby's sleep space. The pillow itself doesn't present any pregnancy-specific risk.
Back sleeping is generally advised against from the second trimester onwards, because the weight of the uterus can compress the inferior vena cava and reduce blood flow. A body pillow positioned behind the back can help prevent unintentional rolling onto the back during the night.
U-shape pillows wrap around the body with support on both sides; C-shape pillows have one curve; straight body pillows are essentially long bolsters. Simba's Body Pillow is a long curved shape, which suits side sleeping with bump and knee support.
Possibly. Sciatic nerve pain in pregnancy is often aggravated by misalignment of the pelvis when side sleeping; a body pillow that keeps the legs stacked and the pelvis neutral can reduce that pressure. It's not a treatment for sciatica, but it removes one of the postural triggers.
Yes, though there's an honest size adjustment. A long body pillow takes up meaningful bed space; couples in smaller beds may find a king or super king mattress more comfortable to share.
