Do You Need a Box Spring? (Probably Not, and Here's Why)

Box springs used to be a given. You bought a mattress, you bought a box spring, that was just how a bed worked. These days, that's mostly not true anymore, and for most modern bed frames, adding one is an unnecessary step rather than a required one.

What a box spring actually does

A traditional box spring is a wood frame wrapped in fabric, with springs or a similar structure inside, designed to sit under a mattress and absorb shock while raising it to a comfortable height. It was built to pair with older bed frame designs that used a simple metal frame with minimal support in the middle, which meant the mattress needed help from underneath to stay properly supported.

Why most modern beds don't need one

Modern bed frames, especially platform-style beds, are built to support a mattress directly. Instead of relying on a separate box spring, they use closely spaced wood or metal slats, side rails, and center support legs to do that job themselves.

Our Bushwick, Louis, and Holly bed frames are all built this way, with slats and center support doing the structural work a box spring used to handle. Adding a box spring on top of a frame like this isn't just unnecessary, it can actually push your mattress up to an awkward height and, in some cases, isn't compatible with how the frame is designed to work.

When you might still want one

There are a few situations where a box spring, or a low-profile foundation, still makes sense:

• You have an older frame that genuinely needs the support, typically a simple metal frame with just a perimeter rail and no slats.

• You want more height. Some people simply prefer a taller bed for getting in and out more easily, and a box spring or foundation is one way to add a few inches.

• Your mattress warranty specifically requires one. Some traditional innerspring mattress warranties are written around box spring use, so it's worth checking your mattress documentation specifically if you're unsure.

What to check instead

If you're setting up a new platform or slatted frame, the more useful question isn't "do I need a box spring," it's "is my mattress compatible with slats." Most memory foam and hybrid mattresses are designed to work directly on a slatted base. If you're working with a traditional innerspring mattress, it's worth a quick check with the mattress manufacturer, since a few models are built specifically to be paired with a solid or box spring foundation.

The bottom line

For a modern platform or wingback frame with slats and center support, like Bushwick, Louis, or Holly, a box spring is almost always an unnecessary extra purchase, not a required one. Skip it unless your specific mattress calls for it or you're after the extra height, and put that budget toward a headboard, bedding, or something else the room actually needs.
