Quick Answer
Plac Oct 18, 2026 · Amazon.com: Derila Pillow ing a pillow under the knees while sleeping is a postural support technique designed to maintain the natural curve of the lower back. It primarily suits back sleepers who experience tension in the lumbar region. While effective for spinal alignment, its key limitation is that it is not a medical treatment for chronic conditions and may not provide relief for those with specific structural injuries.
What Is Pillow Under Knees Sleeping?
Pillow under knees sleeping refers to the practice of elevating the legs slightly to reduce the pull on the psoas muscle and the lower spine. While many use standard bed pillows, others opt for specialized memory foam, ergonomic wedges, or cooling pillows designed specifically for this purpose.
- How it’s used: A sleeper lies flat on their back and slides a pillow directly beneath the bend of the knees.
- Who it targets: Primarily back sleepers looking for neutral spinal alignment. Side sleepers generally use a similar technique by placing a pillow between their knees instead of under them.

Additionally, there is no guarantee of improvement for deep-seated musculoskeletal issues.
