How Do You Know When to Replace Your Box Spring?

The first step to building a fantastic bed that helps you fall asleep quickly, stay asleep deeply, and rest all the way until morning is a high-quality, supportive mattress. This is only the beginning, though! You also need something to support the mattress itself so it lasts as long as it should. This means giving just as much thought to your box spring as the mattress itself.

The Importance of a Box Spring

Just like your mattress supports you, it needs something to support it. The purpose of a box spring is actually threefold: (1) to raise the mattress's height, making it easier to climb in and out of bed, (2) to absorb shock and reduce wear to the mattress, and (3) to create a flat and firm structure for the mattress to lie upon. It is quite possible you could see your mattress provide full support for longer, plus enjoy your nights more, with the right box spring.

When to Replace Your Box Spring

As you can see, there are many important functions of a box spring. If you’re wondering when to replace your box spring, the easiest answer is to buy a new box spring whenever your current one stops doing what it is supposed to do! It’s also possible that you bought a cheap box spring, and it isn’t holding up to the test of time. A low-quality box spring may last a few years, while a good quality one can last more than a decade. Most will last around eight to 10 years.

Yes, a box spring can and will eventually wear out. If you didn’t replace the box spring at the same time as your last new mattress purchase, it’s quite possible that now is the time to do so. Is your mattress suddenly sagging? This is because the constant pressure of use over time starts to weaken the coils, which reduces their ability to carry out their function as a shock absorber and support platform for your mattress. 

Knowing when to replace your box spring doesn’t have to be hard. Here are a few signs that your current box spring needs to be replaced:

  • It makes a creaking or squeaking noise when you lie in bed
  • If you can see any sagging or bowing
  • If you can see any bending or damage to the steel grid
  • It is more than 10 years old
  • It is hard to climb into bed

Box Springs From City Mattress

You don’t want just any old box spring, though. You know there are great products out there. You’re right! The best box springs are strong, sturdy foundations crafted from high-quality wood. For example, our City Mattress Parks Collection Arches Foundation is made from premium wood for maximum durability, and has a full 10-year warranty. It is offered in two heights, 9" Standard or 6" Low Profile. Our City Mattress Parks Collection was specifically made so you can get a high-quality product at a value price. Whether you pair it with one of our mattresses or not, this foundation helps make that possible! We also carry a Beautyrest foundation and a Sealy Posturepedic foundation

We also encourage you to consider PranaSleep options that come with Euroslats, either a traditional Euroslat Foundation or an adjustable Euroslat bed base. The slats in a EuroSlat Foundation are hard beechwood imported from Germany and secured in rubber couplets that are designed to pivot side to side and head to toe, contouring to your natural body curves. These couplets, also known as “adjusters,” are designed to move under the weight of your body as you sleep. This ability to be pressed down means a EuroSlat Foundation offers more pressure relief than a mattress alone can provide. The slats around the hip area are adjustable, providing a customized level of comfort. By sleeping on a mattress with this kind of foundation, you will experience less pressure on your shoulders, hips, and mid-section. That is because the flexing of the slats helps the "hot spots" of your body and reduces pressure to create greater blood flow.

We also have box spring alternatives to consider, like an adjustable bed base and a bunkie board. Just because you have a box spring right now doesn’t mean you need to replace it with something the exact same.

You need more than a mattress to sleep great and more than just a mattress salesman to help you create your perfect sleep system. That is why here at City Mattress, we don’t have salespeople in our stores. We have Sleep Experts who know a lot about sleep and want to help you achieve your best night of true rejuvenation. For you, this may entail buying a new box spring that is better suited for your comfort preferences and will keep your mattress supported for years to come.
