Quick Answer
Using a pillow between the legs is a common sleep posture aid designed to maintain pelvic alignment and reduce strain on the lower back and hips. It typically suits side sleepers who experience discomfort from their knees knocking together or spinal rotation during the night.

FAQ Section
Are ergonomic pillows worth it?
Whether an ergonomic pillow is worth the investment depends on your specific discomforts. For many, the targeted support they provide for the neck or legs can significantly improve sleep quality compared to standard flat pillows.
Do memory foam pillows really help with sleep comfort?
Memory foam is effective for comfort because it distributes weight evenly and reduces pressure points. In the context of leg pillows, it prevents the knees from pressing together painfully.
How long does it take to adjust to a new pillow?
Most sleepers require an adjustment period of 3 to 10 days. Your body needs time to adapt to a new postural alignment, especially if you have been sleeping without support for years.
Are there downsides to cervical or leg pillows?
The primary downside is the potential for restricted movement. If you move frequently in your sleep, a specialized pillow can sometimes become an obstacle or fall out of bed, briefly interrupting your sleep cycle.
