Last updated: October 18, 2026 8:00:00 AM

What Is the Sleep Number Response Fit Pillow?
The Sleep Number Response Fit Pillow is a premium memory foam ergonomic pillow. It is engineered to maintain its shape throughout the night, providing a consistent surface for spinal alignment.
It is primarily used by individuals who experience discomfort from pillows that flatten or shift.

It targets:
- Side Sleepers: To fill the gap between the shoulder and neck.
- Back Sleepers: To cradle the head while supporting the natural curve of the cervical spine.
