Split Queen Box Spring Questions Answered

1. Is There Such A Thing As A Split Queen Box Spring Or A Split Foundation?
Yes—split queen box springs and split foundations are very real, and they solve a very specific problem. Standard queen box springs are one large piece, and that can be a nightmare when you’re trying to get it up a tight stairwell or around a sharp corner. That’s why mattress manufacturers created a two-piece version. It gives you the same size and support but in two smaller, easier-to-move halves.

2. Where Can You Find A Split Queen Box Spring?
You can find them at just about any mattress store that carries quality products. Not all stores will keep them on the floor, but most have access to order them through their regular manufacturers. At STL Beds, we offer split queen box springs for exactly these kinds of situations—tight turns, tricky staircases, or low ceilings.

3. Do Mattress Retailers Stock Split Queen Box Springs?
Many retailers don’t keep split queen box springs in stock due to limited demand. But ordering one is usually no problem. Depending on the manufacturer and your location, it can take anywhere from a few days to a couple of weeks to get it in. We do our best to speed up that timeline for STL Beds customers in St. Louis and beyond.

4. What Are The Measurements Of A Split Queen Box Spring?
A standard queen box spring is 60 inches wide by 80 inches long. When split, each half measures 30 inches by 80 inches. Side by side, they equal the full queen size. This makes them much easier to move through tight or awkward spaces without compromising support.

5. Can You Cut A Box Spring In Half?
Technically, yes—you can cut anything in half. But should you? Probably not. Cutting a box spring can destroy its structure and eliminate the very support your mattress needs. Even worse, it voids any warranty from the manufacturer. If you’re trying to fit through a narrow space, a properly built split queen is the right—and safe—solution.

6. Why Do Mattress Manufacturers Make Split Queen Box Springs And Split Mattress Foundations?
They’re made for real-life homes, not just showroom floors. Older houses, basements, tight staircases, or apartments with narrow doors can make moving a standard queen box spring impossible. A split version lets you maneuver each half with ease—no wedging, bending, or damaging drywall required.

7. How Strong Are Split Box Springs Compared To One-Piece Box Springs?
A lot of people think two pieces mean weaker support—but that’s not the case. In fact, split box springs can be a little stronger. They require extra framing—more wood and often additional steel—to hold their structure independently. Once in place and supported properly, they perform just as well as a one-piece version.

8. Do Split Box Springs And Foundations Come In Low Profile?
Yes, many brands offer low-profile versions to help reduce bed height. This is especially useful if your mattress is thick or you prefer a lower sleeping surface. Just keep in mind that “low profile” can vary in height by brand, so always check with your mattress dealer to confirm the exact measurement before ordering.

9. What Is The Cost Of A Split Box Spring?
Split box springs typically cost more than one-piece versions—expect to pay about $50 to $200 extra. Why the price bump? It comes down to materials and labor. You’re essentially getting two custom-built frames instead of one, and that takes more resources. The good news is it’s a one-time investment that saves a ton of stress on moving day.

10. Can I Use A Bed Skirt Or Dust Ruffle On My Split Box Spring?
Yes, absolutely. The outside dimensions of a split queen box spring are exactly the same as a one-piece version. Your existing bed skirt, dust ruffle, or bedding will fit just fine. No need to buy anything new or modify your look.

11. Do I Need A Special Supporting Steel Bed Frame Or Wood Frame For A Split Queen Box Spring Or Split Foundation?
Yes—you’ll want to make sure your frame supports the center of the bed, not just the edges. Split box springs need a center rail or support beam to keep the two halves stable and in place. Without it, they can shift or sag over time, which affects both comfort and durability. A good quality frame from STL Beds will keep everything aligned and properly supported.

Split Box Spring Vs. Regular Box Spring

Which Is Better? A Split Box Spring Or A Regular Box Spring?

The purchase of a box spring is something most people overlook. Today we are going to rundown these two different mattress support systems, but the fact is, even in the mattress business this is boring stuff so bear with us. A boxspring is boring. It just sits there like a foundation its other commonly called name and does 2 important jobs. Job one is to be a support system for the mattress. The second task is to elevate the mattress to a comfy height while simultaneously keeping it from falling through the steel bed frame. So what’s the big deal about Split Box Spring vs Regular Box Spring? Is there a difference? Actually, there is and there are a few things you will definitely want to consider before you buy one.

Which Base Should You Buy?

1. You need to consider where you will be putting this mattress set. If you plan to place it in your current home and you have a one-piece then of course the best route may be to stay with a one-piece mattress foundation. You may want to consider your future homes. For those of you who move frequently or know the mattress set may have to go upstairs or downstairs, you may want to give some extra thought to the 2 pieces split variety. It is important to remember that tight turns, stairways, and low overhangs over stairs often create real problems when moving and they may not allow access in solid one-piece configurations. In such a case you may end up back out buying yourself a new mattress base at the cost of an entire foundation.
2. A second reason to consider a two-piece split foundation vs. a regular foundation is that there is more wood and or steel in the overall construction of the foundation.  This is one of the primary reasons king-size box springs nearly always come in a split design. The added strength from the extra steel and wood make them ideal for people who are heavy, slightly overweight or just prefer high-quality support under their mattress.
3. 2 piece varieties are very lightweight utilizing 2 smaller pieces making them easier to carry and maneuver through the cramped quarters of an apartment in our house. Many times one person can handle them by themselves.

• Can You Put A Mattress On A Frame Without A Box Spring?

When a Box Spring Isn’t Necessary. Despite the benefits, sometimes using a box spring isn’t worth it. Many bed frames today are designed to go without them and already provide needed support.

• Can You Use 2 Mattresses Instead Of A Box Spring?
