Is It Time to Replace Your Box Spring Too?

Upgrading your mattress is one of the best investments you can make for better sleep. But many customers wonder: “Do I really need to replace my box spring too?” It’s a fair question and the answer depends on several factors, including the age, condition, and type and size of mattress you’re buying.

What Is a Box Spring?

Back when box springs first became common, innerspring mattresses were much thinner, and one of the primary purposes of a box spring was to add bounce and absorb shock. This helped balance out the feel of the bed and extend the lifespan of older mattress models.

Although the name “box spring” has stuck, many modern bed foundations don’t contain springs at all. Instead, they’re often just a sturdy, fabric-wrapped wooden or metal-framed box with slats on top for support. These modern mattress foundations still provide an array of comfort-enhancing benefits, including:

• Elevating the mattress
• Absorbing shock and reducing wear on the mattress
• Supporting weight evenly across the bed
• Improving airflow beneath the mattress

Do All Mattresses Still Need Box Springs Now That They’re Essentially Just Empty Boxes?

Today’s thicker mattresses often require more stable support than the old-school flexible box springs could provide. Depending on your mattress type, there are several support options:

• Modern box springs – best for traditional innerspring mattresses
• Platform beds – solid wood or slatted surfaces that provide firm, even support and airflow
• Adjustable bases – motorized frames for latex mattresses or specially made hybrid mattresses that can raise or lower the head and foot of the mattress
• Slatted foundations – beds with evenly spaced wooden slats

When Should You Replace Your Box Spring?

It’s More Than 8–10 Years Old

Like mattresses, box springs degrade over time. The slatted foundation may have weakened or even have cracked slats. Using an old foundation can shorten the life of a new mattress.

It Squeaks, Creaks or Bends

If you hear noises when you sit or lay down, or if the box spring visibly sags, it’s no longer doing its job. Uneven support can wear down a new mattress and cause discomfort.

You’re Switching Mattress Types

Most modern memory foam or hybrid mattresses require a firmer, flatter surface. A traditional box spring may not provide the stability these materials need, even if it's new.

Visible Damage or Stains

If the frame is broken or warped, or if there are signs of water damage, mold, or pests, replace the box spring immediately.

You Have a Cat (or Several)

Many box springs have a thin fabric cover on the bottom, which cats love to tear into so they can crawl up inside. If your cat has clawed through the material, you’ll likely end up with holes, hanging fabric or a shredded underside.

What Happens If You Don’t Use a Foundation?

Skipping a foundation entirely, by placing a mattress directly on the floor, can have several drawbacks:

• Reduced airflow, which can cause heat retention or mildew
• Faster wear and sagging due to uneven pressure
• Difficulty getting in and out of bed, especially for older adults
• Voided warranty, as many mattress manufacturers require proper support

While some people like the minimalist look of a mattress on the floor, using an elevated foundation will help your mattress last longer, sleep cooler, and feel more comfortable.

Are Platform Beds and Adjustable Bases Better?

That depends on your needs. Platform beds are great for simplicity and affordability, while adjustable bases offer added comfort for reading, watching TV or relieving issues like snoring or acid reflux, especially for older adults.
