About this item
The 4-inch BiFold Box Spring by Zinus is an innovative folding mattress foundation designed for mobility and functionality.

No assembly required; simply open the box, slide the foundation out and unfold; it will immediately open to the shape of a box spring. Worry-free 5-year limited warranty.
