What goes under a mattress?


When it comes to setting up a comfortable and supportive sleeping environment, the mattress is undoubtedly the star of the show. But have you ever wondered what goes under a mattress? In this article, we will explore the various components and accessories that are commonly used to enhance the performance and longevity of a mattress.

Box Spring or Foundation

Box springs or foundations are often used as a base for mattresses. They provide support and help distribute the weight evenly, preventing sagging and extending the lifespan of the mattress. Box springs typically consist of a wooden frame with springs or metal grids inside, covered by fabric. They are designed to absorb shock and reduce motion transfer.

Bed Frame

A bed frame is another essential component that goes under a mattress. It provides stability and elevates the mattress off the ground. Bed frames come in various styles, such as platform beds, adjustable beds, and traditional bed frames with headboards and footboards. The choice of bed frame depends on personal preference, style, and the type of mattress being used.

Mattress Topper

A mattress topper is a removable layer that sits on top of the mattress. It is often used to add extra comfort, cushioning, or support to the mattress. Mattress toppers can be made from various materials, including memory foam, latex, down feathers, or synthetic fibers. They can also help regulate temperature and provide pressure relief, making them a popular choice for those seeking to customize their sleeping experience.

Mattress Pad

A mattress pad is similar to a mattress topper but typically thinner and designed to protect the mattress from stains, spills, and general wear and tear. It acts as a barrier between the mattress and the sleeper, helping to keep the mattress clean and hygienic. Mattress pads are often made from quilted fabric and can be easily removed and washed.

Bed Skirt

A bed skirt is a decorative fabric panel that hangs down from the mattress to the floor, covering the space between the mattress and the floor. It is primarily used to conceal the bed frame or any storage space underneath the bed. Bed skirts come in various styles, colors, and lengths, allowing you to add a touch of elegance or match your bedroom decor.

Mattress Encasement

A mattress encasement is a protective cover that completely encloses the mattress, acting as a barrier against allergens, dust mites, bed bugs, and spills. It is typically made from a waterproof or water-resistant material and has a zipper closure. Mattress encasements are especially useful for those with allergies or asthma and can help prolong the life of the mattress by preventing damage.


In summary, several components and accessories go under a mattress to enhance its performance, comfort, and longevity. These include box springs or foundations, bed frames, mattress toppers, mattress pads, bed skirts, and mattress encasements. Each of these elements serves a specific purpose, whether it’s providing support, adding comfort, protecting the mattress, or enhancing the overall aesthetic of the bed. By understanding and utilizing these components, you can create a sleep environment that meets your unique needs and preferences.
