This product is designed to provide excellent support under any mattress. It ships in a compact box and can be easily assembled in minutes — without any tools! Unlike traditional box springs, our foundation can be broken down quickly if you’re moving or need to maneuver around tight corners. A Casper Foundation ensures that mattresses, sleep as they should. Some older box springs or foundations don’t provide a solid surface, causing mattresses to sag from the support breaks. Our Casper Foundations slats are positioned a perfect four inches apart for optimal support. A strong and level foundation helps mattresses perform at their peak for a decade or more, no matter what kind of bed frame they sit on. Casper Foundations and mattresses are the perfect pair. We spent over a year developing the Casper Foundations, so its design has the same considerations as our mattresses.

Easy to put together. Very sturdy. There are screws heads in the bed frame in 3 places down the middle of the frame and the center piece of the foundation sits on the screw heads. So it doesn’t fit flat on the frame. Either the makers of the bed or the foundation need to accommodate this space for the screw heads. I coved the foundation with a fitted sheet since it only comes in one dark color.. Doug. Erie, MI. Wed Jun 24 2026
