Low profile box springs, or foundations, were created as an alternative to regular height versions. Adding a low profile foundation to your mattress lowers the overall height of the bed. Mattress manufacturers have been creating taller and taller mattresses in the last few years. A low profile foundation typically measures 4-5 inches whereas a regular foundation is 9 inches or more. This is a big help when your mattress can measure as tall as 18 inches! What is a box spring/foundation?
Most mattress manufacturers produce low profile box springs that match the new mattress that you're buying. In most cases, the warranty for your mattress requires that you pair it with a foundation. A low profile foundation is just as supportive as a standard-sized box spring. Do I Need a Box Spring With My Mattress?
