Shopping for a new mattress or bed frame? You’ve probably asked yourself: What is a box spring, and do I really need one? The answer is–it depends! With so many types of mattresses and bed frames available today, it’s not always clear whether this once-standard bed base is still a must-have.
We’ll break down what a box spring does, when it makes sense to use one, and how to choose the right foundation for your sleep setup.
First: What is a Box Spring?
A box spring is a sturdy base designed to sit underneath your mattress. Traditionally, a box spring includes a fabric-wrapped wooden or metal frame filled with coils or a grid that adds height, supports the mattress, and absorbs movement. A box spring was once the go-to foundation option for innerspring mattresses, especially if your bed was placed atop a basic metal frame.
So… why did we use box springs in the first place? A box spring supports your mattress, helps extend its lifespan, and adds height to your bed. But as mattress technology has evolved, the need for one now depends more on what type of bed setup you have.
What’s the Point of a Box Spring in Today’s Bedrooms?
The traditional purpose of a box spring was to add comfort, including prevention of aches and pains, and support to an inner-coil mattress setup. Box springs absorbed impact from tossing and turning, protected the mattress from wear, and created airflow underneath, preventing you from getting too hot at night.
But things have changed. Today’s mattresses—especially memory foam, latex, and hybrid options—are often built with multiple layers of support already built in… and cooling technology, too.. That means you might not require that extra spring underneath.
Still, there are a few situations where a box spring can come in handy–and, either way, you’ll still want a bedframe of some kind.
Do All Beds Require a Box Spring?
The short answer is no. Thanks to the rise of modern bed bases and integrated support systems, many bed frames are built to fully support a mattress on their own. Instead of a box spring, your setup might include:
- Platform beds with slats or solid panels, offering low-profile support.
- Adjustable bases for customizable comfort that eliminate the need for extra components.
- Bunkie boards, which will provide a thin, sturdy foundation ideal for foam mattresses or bunk beds.
These options can help you create a streamlined, supportive bed without the extra height or bounce of a box spring.
Why is a Box Spring Necessary in Some Cases?
So, you know that you might not always need a box spring for your mattress. But that begs the question: when do you need a box spring with a mattress?
The answer depends on 1) the type of mattress you own and 2) the kind of bed base you’re working with.
When You Do Need a Box Spring for a Mattress
While it’s not required for every setup, there are still cases where a box spring makes sense. You may want to add one to your bedroom if:
- You’re using an innerspring mattress. These mattresses still benefit from the added bounce and shock absorption that a box spring provides.
- Your bed frame doesn’t have built-in support. Traditional metal frames without slats rely on a box spring to hold the mattress in place.
- You prefer a higher bed profile. Box springs can lift your bed several inches off the ground, making it easier to get in and out, especially if your mattress is lower in height.
In these situations, a box spring helps maintain the structure of your mattress and offers a more traditional sleep experience.
When You Shouldn’t Use a Box Spring with a Mattress
Here are some situations where you probably don’t need a box spring–and in fact, using one could be a bad idea:
- If you have a platform bed. Platform beds feature slats or a solid surface, and often don’t require a box spring at all. These frames provide all the support your mattress needs.
- If you have a memory foam, latex, or hybrid mattress. These are typically designed to rest on firm, flat surfaces. A box spring could even reduce their effectiveness by allowing too much give.
- If you have an adjustable base, it isn’t compatible with standard box springs. Adjustable bases move and bend with your body and mattress.
If your mattress warranty or manufacturer’s instructions specify a particular type of support, that’s your best guide. Skipping the proper base could impact your comfort or void your warranty!
