The Casper foundation was designed to withstand normal wear and tear along with that occasional bounce on the bed throughout its lifetime. Our foundation underwent a series of static load, dynamic load and impact tests that assess the strength and durability of the frame as well as the slats. Additionally, we tested our foundation with our mattress to a long-term durability test standard, ASTM F1566. For ASTM F1566 a 240-pound roller was pressed into the mattress and foundation and rolled back and forth 100,000 times to simulate 10 years of use. Both the mattress and foundation passed with flying colors. For best results, we recommend use within these boundaries.
