1. Quick Answer

A knee pillow is a specialized ergonomic cushion—often hourglass or bolster-shaped—placed between or under the legs to promote neutral spinal alignment. It is most suitable for side sleepers looking to reduce pressure on the hips and lower back. However, a key limitation is that they can be restrictive for active sleepers who frequently toss and turn, often slipping out of place during the night.

2. What Is the Best Knee Pillow for Sleeping?

The best knee pillow for sleeping is typically an orthopedic support tool designed to fill the anatomical gap between the knees (for side sleepers) or under the hamstrings (for back sleepers).

• Type: Most modern versions utilize high-density memory foam, cooling gel-infused foam, or adjustable shredded fills.
  
• Usage: Side sleepers place the pillow between their knees to keep the hips square; back sleepers use bolster-style pillows to maintain the natural curve of the lower spine.
  
• Target Audience: Primarily side sleepers, pregnant individuals, and those exploring ergonomic sleep solutions for general comfort.
