The mattress has a medium tension spring system, a traditional spring. 

Multiple layers of fillings are built on top of the spring system on both sides of the mattress so it can be turned and rotated for a longer life.  The outer cover is a durable, and breathable damask fabric.

The mattress is suitable for use on bed frames with slats or divan bases.
