Knee Pillow for Side Sleepers — Memory Foam Leg Spacer That Aligns Hips and Spine Overnight

Side sleeping without knee support twists the spine all night: the top leg slides forward, rotating the pelvis and pulling the lower back out of line. You wake with hip or back ache and blame the mattress. The fix costs $24.99.

Frequently Asked Questions

How does a knee pillow help back pain?

When the top knee drops to the mattress, it rotates the pelvis, which twists the lumbar spine for hours. The spacer keeps the knees stacked and the pelvis level — so the spine rests straight instead of twisted.

Is it good during pregnancy?

Yes — side sleeping with knee support is the standard comfort recommendation in later pregnancy. The contour shape supports without bulk.
