About This Product

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.

Features

  • The Casper Foundation is designed to provide excellent support under any mattress. A 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. A strong and level foundation helps mattresses to perform at their peak for a decade or more. Easily assembled in minutes — without any tools!
  • Importance of slats: Older box springs’ slats tend to be too far apart, leaving room for a mattress to sag. Our foundation’s slats are positioned a perfect four inches apart for optimal support.
  • Supportive and study: The Casper Foundation was engineered with solid wood, rigorously tested for durability, and proven to stand up to years of sleep.
  • Effortless assembly: The Foundation ships in a compact box and can be easily assembled and disassembled in a matter of minutes — and you don’t need to use any tools.
  • Compatible with standard bed frames, metal bed frames, slatted bed frames, or platforms; but should not be used bunk beds. The foundation cannot be placed directly on the floor.
