Types of Box Springs
Traditional Box Spring: A box spring is a support on which you put a mattress. A traditional box spring has a frame that can be made of wood or metal. This frame is filled with metal springs or a metal grid, hence the name, “box spring”. This type is no longer common today though. Modern mattresses no longer need the support from springs, making springs unnecessary. Most box springs no longer have springs inside the frame. This type is call a mattress foundation, which is the next one on this list.
The Foundation: The foundation style box spring is a box spring that has no springs inside the frame. This is the most common box spring today. It is simple to make and easy to transport.
Low-Profile Box Spring: The low-profile box spring is a box spring that is lower than 7 inches, which is the usual height for box springs.
Ultra-low Box Spring: The ultra-low profile box springs are the thinnest. These box springs are usually just a bunkie board made for all sizes of mattresses.
All-in-One Box Spring: The all-in-one box spring is a foundation with no springs but it has a frame and legs. It earned the name “all-in-one” because it doesn’t need a metal frame to hold the box spring.
