Keep reading to see if this type of mattress base is just what you need to start sleeping your best sleep ever!

What is a Split Box Spring?

Only slightly different from traditional models you’re used to, this kind is similar to a traditional one – only it comes sectioned. They typically come in two separate sections that easily can be pushed or fused together. It’s often, and almost always, with larger bed sizes; a split queen or and king split. The make of a split model is the exact same make you’d see in a traditional one piece, this is just an easier way to connect the box itself.

They are typically two sections that have a frame usually made of wood or steel. Inside the frame is a skeleton of wood and/or steel with coil springs that promote bounce for your mattress. The base’s sections are typically covered by a layer of fabric of padding. When it comes to a split design, you’re basically getting two tinier versions of a single model that come together to make a whole.

Best for:

  • People who move locations frequently
  • People who prefer height
  • People who need extra durability
  • People who need more bounce with their mattress

Not good for:

  • People who are sensitive sleepers
  • People who prefer lower sleep setups
  • Someone who may find the box spring hard to move
  • Restless sleepers


Benefits of a Split Box Spring

They are beneficial because, unlike a traditional one-piece design, these two-piece models are quite easy to move. If you’ve ever had to move a regular one from a house to another or from one apartment to another, you know firsthand just how heavy and cumbersome traditional box springs can be.

Split designs and models bring you the best of both worlds: Extra durability with the lightness of two separate pieces. So you can be sure of two things; you’ll get them in and out of any space and you wouldn’t hurt your back lifting them.

They also offer the same support a traditional one provides once the halves are fused together. The easiest way to fuse two of them is to wrap them together with a fitted sheet. Sometimes, making sure the edges are flush with a bed frame can also prevent the split foundation from slipping around or causing any fusing problems.

Another benefit of these two-piece boxes is the cost. They seem to be a bit less expensive than traditional models. This may be due to the extra step of having to fuse the two halves instead of having a single one sent to you, ready to use. That’s another thing – you’ll save some money on shipping since split ones are a bit lighter than a normal traditional model.


Downsides to a Split Box Spring

Although they will do the job as a traditional design once fused, there is always going to be that gap. These are, after all, two halves of a whole, so naturally, there is going to be a gap in between the two boxes under your mattress. Mind you, it really depends on which type of brand or model you purchase, since there are so many on the market, but typically there’s going to be a gap no matter how you fuse them together.

If you’re someone who is a super sensitive sleeper and you know the space between the two halves is going to keep you awake at night, this may not be the best setup for you. Although the gap would be underneath your mattress, you could still find yourself bothered by this.

Split bases, if not fused correctly, could also prove to be a bit more mobile than traditional ones. This is mostly due to the gap in between spaces. The two pieces can seem to shift or move around if you’re not careful to make sure both pieces are flush together and fit tightly into a bed frame.

Even with a fitted sheet, the pieces of the base can easily slip, causing the fitted sheet to become loose and come undone. This could prove to be problematic if you have to wake up several times a night to readjust the sheets on your mattress since the box spring below is constantly shifting.


Who Should Buy a Split Box Spring?

These things would be best for people who like the added height and durability of a box spring. These would also be great for people who move locations a lot since the split designs are lighter and much easier to move than the usual models and products out there.

They would also be suitable for anyone of any age, just as long as you keep the specifications and particular needs of your product in mind. This type of box spring would be suitable for anybody as long as you realize that these are two halves of a whole and need to be fused together accordingly.


Who Shouldn’t Buy a Split Box Spring?

These two-piece designs may not be the best option for someone who is an extra sensitive sleeper. There will always be a small gap in between the halves of the two pieces, so if you think this is going to bother you, it more than likely would. This could also affect the sag of your mattress. You could add some fillers to fill that gap up if it’s extra bothersome, but this won’t make a great purchase if you are a pickier sleeper.

People who move around in their sleep or restless sleepers should probably steer clear from two-piece models, as well. Since this product has two pieces, any movement could easily shift one of the halves, causing the mattress to shift with it. This could result in the mattress sagging and moving around, causing the fitted sheet or regular sheets to shift along with it.



Overall, the most important thing is finding a mattress and box spring setup that will work for you. A split box setup is much easier to use than a traditional box spring, but if the aforementioned downfalls bother you just by reading about them, odds are they will bother you in real life, too.
