About this item

The 4-inch BiFold Box Spring by Zinus is an innovative folding mattress foundation designed for mobility and functionality. Traditional box springs are hard to maneuver throughout your home, especially in staircases and through doorways, but the BiFold Box Spring is easy to use in tight places. Tougher than it looks - offers the look and functionality of a traditional box spring but made from heavy gauge steel for long-lasting durability. 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.

Returning item. Not at all what we were looking for. Didn't realize it was mostly all metal with a mesh cover.

I never knew there was such a thing! We are so pleased with this purchase. It is thinner than a normal box spring, yet it fits the bed frame perfectly.see moreof the reviewer's review
