bed frame type - boxspring

A conventional box spring refers to a wooden frame, with a thickness akin to a mattress, incorporating coils that provide support to the mattress atop. The fundamental function of a box spring lies in its ability to combat sagging and promote even support for the mattress.

Numerous individuals persistently employ the term “box spring” to describe a supportive base that does not actually house any springs.

Regrettably, such usage is fundamentally incorrect.

If an absence of springs manifests, the object in question cannot, by definition, be classified as a box spring. However, this by no means implies that it fails to serve the identical purpose possessed by a traditional box spring.

A supportive base devoid of coils or springs warrants the moniker of “foundation.”

A foundation typically entails a wooden, metal, or composite framework, utilizing solid wooden framing to cope with the weight exerted by the mattress above. Supports may also comprise metal or composite materials.

The defining characteristic of any foundation lies in its unyielding construction, devoid of any springs.

In most instances, a foundation bestows greater support when compared to a box spring, primarily due to its rigid support structures (which are typically spaced closer together). This is in stark contrast to box springs, which feature flexible supports.

Foundations come with the added advantage of offering varying thickness options. The three main types of foundations are as follows:

  • Foundations with a Full Profile: Full profile foundations span a thickness range of 8-12″ and represent an excellent choice if augmenting your bed’s height is a priority.
  • Low-profile Foundations: If support is your primary concern, but additional height is not a necessity, a low-profile foundation may prove to be an ideal alternative. These foundations boast the same wooden box frame, albeit with a shallower overall height—typically, a range of 3-7″ is considered low-profile.
  • Slat foundation: Although not a traditional foundation, in this section, we will explore the concept of “slat foundations”. These are wooden products that lie flat but still offer adequate support for the mattress.

    Examples of such products include:

    In spite of their lack of thickness, these products generally provide sufficient support for the mattress.

    If you prefer a lower profile, any of these slat solutions will do the job while also saving you some money.

    Now that we’ve discussed the difference between box springs and foundations, the question remains: do you actually need them?

    There are a few instances where a box spring or foundation is necessary:

    • When required by the mattress manufacturer: In many cases, mattress manufacturers specify the type of foundation or box spring to be used. Failure to comply with these requirements can be detrimental to the mattress and may void the warranty. It is essential to be aware of your mattress’s specific needs.
    • When required by your bed frame: If your bed frame lacks slats or the existing slats are too far apart, a box spring or foundation becomes necessary to ensure proper support for the mattress.
    • When seeking additional height: If you prefer the aesthetic or functional benefits of a taller bed, you might consider adding a foundation. This can provide an extra 3-12 inches in height, making it easier to get out of bed.

    can you put a mattress on the floor?

    But what if you want to save money, avoid extra height, and your mattress does not explicitly require a box spring or foundation? Can you place the mattress directly on the floor?

    The answer is yes.

    Placing your mattress directly on a solid floor offers even and consistent support, eliminating the risk of sagging.

    Critics of this practice primarily cite hygiene and humidity as potential drawbacks.

    A mattress placed directly on the floor is more exposed to dust, dirt, bacteria, insects, and other microscopic particles commonly found on the floor.

    To address this concern, consider using a mattress encasement. A mattress encasement is a six-sided product that fully encloses your mattress, providing protection and helping to keep it clean and fresh for longer.

    #2. Humidity

    If you reside in an area known for its high humidity levels, you might want to reconsider the idea of laying your mattress directly on the floor. Placing your mattress on the floor obstructs proper airflow around and within it, which can lead to troublesome consequences in a humid environment.

    In such conditions, it becomes highly likely for mold or mildew to accumulate beneath your mattress, eventually causing significant issues.

    Therefore, given these considerations, the question arises: should you opt for a box spring or a foundation? Which one is more suitable for you?

    • You desire additional height.
