In this article, we will help guide you through the process of finding the perfect box spring for your needs, focusing on the factors that affect the cost and how to make a well-informed decision.

Understanding Box Springs

A box spring is an essential part of your bed setup, as it provides support and stability to your mattress.

As you explore the cost of a king-size box spring, it's important to consider the various factors that can influence the price.

When shopping for a box spring, you'll come across numerous options.

There are standard box springs, which typically have a wooden frame and steel coils that help to evenly distribute your body weight across the mattress.

Then, there are low-profile box springs, which are thinner and ideal for those who prefer a lower bed height.

Additionally, you might encounter split box springs, consisting of two separate pieces that are easier to maneuver in tight spaces.

Why Choose a King Size?

Space Considerations

When choosing a bed, it's important to consider the space available in your bedroom.

A king size box spring offers a spacious sleeping area, especially for couples who need extra room to stretch out.

With a typical dimension of 76 inches wide and 80 inches long, a king size bed provides ample space for both partners to sleep comfortably without disturbing each other.

Consider measuring your bedroom before making a purchase to ensure that a king size box spring will fit comfortably.

You should account for additional furniture, walking room, and the size of your home's doorways for easier transportation and assembly.

Comfort Factors

A king size box spring can significantly enhance your sleeping experience by providing:

Better Support

King size box springs are designed to evenly distribute the weight of your mattress, providing optimal support and reducing the likelihood of sagging.

Motion Isolation

The larger size of a king size bed means there is more space between you and your partner, which can help minimize disturbance caused by their movements during the night.

Extra Sleeping Space

The generous surface area of a king size bed allows you to spread out comfortably, which can be particularly beneficial for individuals who tend to toss and turn or sleep with pets.

Comparing Box Spring Costs

When looking for a king-size box spring, you'll notice that prices can vary quite a bit.

Generally, the cost of a king-size box spring ranges from $100 to $500.

Several factors influence the price, such as the material, brand, and additional features.


The most basic king size box springs typically cost around $150 to $250.

These budget-friendly options may be of lower quality materials and construction but will get the job done for some time.

Keep in mind that you may need to replace these options sooner than a higher-end box spring.


On the other hand, mid-range box springs can run between $300 and $500.

These options usually offer more durability and support, meaning they are more suitable for long-term use.

The materials tend to be of better quality, and some may even have additional features such as foam layering for extra comfort and support.


If you're willing to invest in a luxury king-size box spring, you can expect to pay anywhere from $600 to over $1000.

These high-end models are often made with the best materials and construction techniques, ensuring that they provide optimal support and have a longer lifespan.

They may also come with added features like cooling systems and adjustable settings for a truly personalized sleeping experience.

Factors Affecting the King Size Box Spring Price

When considering a king size box spring, it's important to understand the factors that can influence its price.

Manufacturing Materials

One of the most significant factors that affects the price of a king size box spring is the materials used in its construction.

Box springs are typically made from wood, steel, or a combination of both.

  • Wooden box springs - more affordable but may lack the durability of steel options
  • Steel box springs - known for their strength and longevity, but more expensive

Typically, wooden box springs are more expensive due to their sturdiness and classic appearance.

However, metal box springs can be more affordable and lighter, making them easier to move.

The type of wood or steel used, as well as any other materials like the fabric covering, can also impact the price.

Higher-quality materials often result in a higher price tag.

Brand Reputation

Another factor to consider when shopping for a king size box spring is the reputation of the brand.

Some well-known brands may charge a premium for their products due to factors like customer loyalty or a track record of producing high-quality box springs.

On the other hand, lesser-known or newer brands might offer more affordable options but could have a lower overall quality or less established reputation.

It's important to weigh the benefits of a well-known brand against your budget and personal preferences when making your decision.

Additional Features

Lastly, the presence of additional features can also affect the price of a king size box spring. Some examples of these features include:

1. Built-in Storage

Some box springs come with built-in drawers or other storage solutions, which can be convenient but may also increase the cost.

2. Easy Assembly

Box springs that are easy to assemble or disassemble for moving or storage purposes might also come with a higher price tag.

3. Adjustable Firmness

Some box springs offer adjustable firmness options, which can be appealing to those who prefer customizable support.

Keep in mind that while these additional features can enhance your overall sleep experience, they may also contribute to a higher price.


A good warranty can provide peace of mind and protect your investment in the long run.

Box springs with longer and more comprehensive warranty coverage tend to be more expensive upfront, but they might save you money on replacements or repairs in the future.

Ways to Save on a King Size Box Spring

There are several ways to find a high-quality box spring at a fraction of the cost.

Shopping During Sales

One of the easiest ways to save money on a king size box spring is by taking advantage of sales and discounts.

Retailers often offer substantial markdowns during:


Major holidays such as Black Friday, Presidents' Day, and Labor Day typically see huge discounts in the mattress industry.

End-of-Season Clearance

Retailers often clear out inventory at the end of seasons to make room for new products. Keep an eye out for these sales to snag a great deal.

Online Exclusive Sales

Many online retailers offer special promotions and discounts that you might not find in brick-and-mortar stores.

Sign up for newsletters or follow retailers on social media to stay informed about these sales.

Choosing Less Known Brands

While well-known brands can offer high-quality products, they often come with a hefty price tag.

Instead, consider researching and purchasing from less-known brands, which can offer equally good quality at a lower cost.

Some tips for choosing lesser-known brands include:

  • Reading online reviews from customers to get a sense of the quality and durability of the product.
  • Checking for trial periods and warranties that can give you peace of mind about the purchase.
  • Visiting showrooms or trying out mattresses at friends' homes to gauge the comfort and support of the box spring.

Second Hand Purchases

If you're not opposed to buying a used king size box spring, you can save a significant amount by opting for second-hand purchases.

Here are some tips for buying a used box spring:

Check the Condition

Make sure the box spring is clean, sturdy, and free of any defects or damage. Also, inquire about any lingering odors or allergens from the previous owner.

Ask About the Age

A box spring's lifespan is generally eight to ten years. Ensure the product you're buying has not exceeded this timeframe, or you might end up having to replace it shortly.

Negotiate the Price

When buying second-hand, you have more room to negotiate and potentially bring the price down even further.

Do Big Retailers, like Walmart and Amazon, Offer Cheap King Size Box Springs?

Shopping for King Box Spring
