Kneeling chairs can offer real relief for pregnancy-related back pain — but there are important considerations for each trimester. Here’s what Australian mums-to-be need to know before buying one.
Why pregnancy causes back pain while sitting
During pregnancy, several things change that affect how sitting feels:
- Anterior pelvic tilt: As the belly grows, the centre of gravity shifts forward, pulling the pelvis into a forward tilt and increasing the curve of the lower back. Standard chairs at 90 degrees often exacerbate this.
- Relaxin hormone: The body produces relaxin to loosen ligaments in preparation for birth — making joints less stable and poor sitting posture more uncomfortable.
- Sciatic nerve pressure: The growing uterus can press on the sciatic nerve, and sitting in a standard chair position increases this pressure for many women.
How a kneeling chair can help during pregnancy
The forward-tilted seat angle opens the hip angle and encourages a more neutral pelvic position — which can directly counter the exaggerated anterior tilt that causes pregnancy-related lower back pain. The open hip position also reduces direct pressure on the sacrum (tailbone area), a common source of pregnancy back pain.
For correct positioning that reduces back strain, read our guide on how to sit on a kneeling chair correctly — the weight distribution principles are especially important during pregnancy.
Trimester-by-trimester guide
🟢 First trimester — generally fine
Using a kneeling chair in the first trimester is generally fine for most women. The body hasn’t changed significantly in terms of centre of gravity, and the main benefit is getting used to the chair before you need it most. Start with short sessions of 20–30 minutes and build up gradually, same as any new user.
🟡 Second trimester — most beneficial
This is typically when kneeling chairs provide the most benefit during pregnancy. The belly is growing but still manageable, and many women find the open hip position more comfortable than a standard chair. The reduced lower back pressure is particularly appreciated at this stage. Keep sessions to 30–45 minutes and get up to walk and stretch regularly.
🔴 Third trimester — proceed with caution
This is where individual variation matters most. Some women continue to find a kneeling chair comfortable right up to late pregnancy. Others find that as the belly grows very large, getting into and out of the kneeling position becomes awkward or uncomfortable. Listen to your body — if getting in and out requires significant effort or causes discomfort, that’s a signal to stop. A fixed-base chair is safer than a rocking base in the third trimester.
Important safety considerations
- Getting in and out safely: Position the chair near something you can hold for support as your pregnancy progresses.
- No rocking chairs for later pregnancy: The rocking motion may feel less stable when your centre of gravity has shifted significantly. A fixed-base chair is safer in the third trimester.
- Short sessions only: 20–30 minutes maximum, then stand, walk, or change position.
- Shin comfort: Some women experience increased fluid retention in the legs during pregnancy, which can make shin pressure from kneeling pads more noticeable. If your shins feel uncomfortable, switch to a regular chair.
If you want back support combined with the posture benefits, a kneeling chair with a backrest is a safer option during pregnancy. See our guide to kneeling chairs with backrest vs without to understand the difference.
✅ Potential benefits during pregnancy

- More comfortable than standard chairs for many women
⚠️ Considerations and cautions
- Always check with your midwife or GP first
- Getting in/out becomes harder in third trimester
- Avoid rocking base in late pregnancy
- Leg fluid retention may increase shin discomfort
- Short sessions only — never sit for hours
