A leg pillow keeps your legs in a steadier position when you lie down. For some people with back pain, it makes sleeping on the side or back more comfortable, especially if the pain is worse in the morning.
This guide covers what the NHS says about back pain, hip pain and swollen legs, the main types of leg pillow, and thirteen leg pillows to compare.
General information, not medical advice; see a doctor if back pain does not improve after a few weeks, or follow your surgeon’s instructions after surgery.

Leg pillow basics
- The NHS says back pain usually improves within a few weeks, and suggests staying active and not staying in bed for long periods.[1]
- The NHS suggests putting a pillow between your legs for extra support in bed if you have pelvic and lower back pain in pregnancy.[4]
- The NHS suggests raising swollen ankles, feet or legs on a chair or pillows when you can, which is what a wedge is for.[3]
- See a GP if hip pain stops you doing normal activities, affects your sleep, or has not improved after 2 weeks of home treatment.[2]
- Match the shape to the job. Knee pillows go between the knees, bolsters go under or between the legs, and wedges raise the legs.

Some Reasons for Back Pain
The NHS says back pain, particularly lower back pain, is very common, and it usually improves within a few weeks but can sometimes last longer or keep coming back. A common cause is an injury such as a pulled muscle (strain). Medical conditions such as a slipped disc or sciatica can also cause it, and very rarely it is a sign of a serious problem.[1]
For pain that does not improve after a few weeks, or pain that stops you doing your day-to-day activities, the NHS advises seeing a GP.[1]
Remedies and Treatments for Back Pain
The NHS says back pain often improves on its own within a few weeks, and suggests that you:[1]
- Stay Active – Continue your daily activities and do not stay in bed for long periods.
- Use Heat or Cold – Wrap an ice pack or bag of frozen peas in a tea towel to reduce pain and swelling, or use a heat pack or hot water bottle wrapped in a tea towel for stiffness and muscle spasms.
- Take Pain Relief – Ibuprofen or another anti-inflammatory can help, but it may not be suitable for everyone, so check with a pharmacist or GP.
- Try Exercises and Stretches – Stop if the pain gets worse and see a GP for advice.
Good bedding and pillows can add comfort, but they are not a treatment on their own.
Types of Leg Pillow for Back Pain
- Knee Pillows – These go between the knees when you sleep on your side. The NHS suggests a pillow between your legs for pelvic and lower back pain in pregnancy.[4]
- Half-Moon and Bolster Pillows – These fit under or between the legs, and some also work behind your lower back. Our lumbar pillow guide covers pillows made for your lower back.
- Wedge Pillows – These raise the legs. The NHS suggests raising swollen ankles, feet or legs on a chair or pillows when you can.[3]
- Cooling Gel Pillows – A gel layer keeps the surface cooler than plain foam. See our gel pillow guide for more.
For hip pain, the NHS says to see a GP if it stops you doing normal activities or affects your sleep, or has not improved after treating it at home for 2 weeks.[2]
