Rest assured, a zoned power-packed wrapped steel unit offers reinforced structural support where you need it most, while the fully foam encased perimeter provides edge to edge support for a larger sleep surface and supportive sitting surface. The height of this mattress is 13.75". The Pillow Top mattress is backed by a 10 Year Non-Prorated Warranty.
