Support core
- GhostBed Massage Foam
- 7.5 inches of high-density base foam; no coils
- GhostBed Massage Hybrid
- 6 inches of individually wrapped reinforced coils over 1.5 inches of high-density base foam
Why it matters: This is the main $300 construction decision. Foam favors a closer, quieter contour. Reinforced pocketed coils add spring-back, open space for airflow, and more perimeter structure while leaving the massage system unchanged.
