A foundation is a modern box spring without the springs. It uses a steel grid or wood slats to provide even support without bounce—ideal for today’s mattresses.

Understanding whether you need a boxspring or foundation for your mattress is crucial. Often, these terms are used interchangeably, with modern boxsprings essentially acting as foundations without actual springs. The necessity of a boxspring or foundation depends largely on your bed frame.

For Traditional Bed Frames: If your bed frame has fewer than 10 slats or crossbars, a boxspring or foundation is necessary. It provides a level, stable surface, ensuring your mattress is properly supported. This helps in maintaining the mattress's structure and can extend its lifespan.

For Platform Beds: Many contemporary bed frames are designed as platform frames. These usually include 11 or more slats or a solid steel grid, eliminating the need for a separate foundation. Platform beds offer sufficient support for your mattress on their own.

Adjustable Bases: The rising popularity of adjustable bases, which can raise and lower your head and feet, has also influenced mattress support. These bases are self-supporting and designed to offer optimal mattress support without needing an additional foundation.

Importance of Proper Support: Regardless of your bed type, ensuring your mattress rests on a solid, level surface is vital. This not only helps in keeping your spine properly aligned but also enhances the overall comfort and durability of your mattress.
