A box spring is a bed base with a wooden frame and either springs or metal rods that provide support to a mattress. It is a type of foundation for mattresses. The box spring is usually the same size as the mattress that sits on it.
So, what does a box spring do? While the mattress provides support to the human body, the box spring ensures that the mattress itself is properly supported. It provides a stable surface for your mattress to rest on and absorbs shock, reducing wear on the mattress. This helps ensure your mattress maintains a long comfort life.
Box springs also raise the height of a mattress to make it easier to get in and out of bed. In a complete bed set, box springs are typically placed on top of a wooden or metal bed frame that's connected to the headboard and footboard. It's also common to see mattresses and box springs used together without a complete bed. Many sleepers who don't feel the need to have a decorative looking bed will place their box spring directly on the floor, or on casters that stand on the floor. Depending on what you need, there are different types of box springs.
Although most modern mattresses don't need a box spring to be comfortable some mattress warranties still require a box spring. In some cases adding a box spring to your mattress enhances the comfort and support you get from your bed. The information below should answer the question, 'Do I Need a Boxspring?'

Over the last several years, advancements in sleep technology have resulted in mattresses that are a lot taller than they used to be. For this reason, many manufacturers produce low profile box springs. as well as ultra-low profile box springs.
The difference in height is completely aesthetic. There's no difference in the amount of support they provide to the mattress. Whether you use a standard or low profile box spring, you can count on your mattress getting the support it needs.
Standard box springs measure 9 inches in height.
Low profile box springs measure between 5 and 5.5 inches in height.
Ultra-low box springs measure 2 inches in height.
Most manufacturers require that a mattress be supported by a box spring to file warranty claims. An exception to this is when a mattress lies on a platform bed or adjustable base. Since platform beds feature either wooden slats or a deck, the mattress doesn't need the extra support of a box spring.
The warranty also requires that the box spring be in good enough condition that it will not damage the mattress. Learn how to tell when you need a new box spring.
