*Relative to other adjustable-air king mattresses, not to all mattress types.

Key idea: A king size adjustable-air mattress will almost always cost more than smaller sizes in the same series, since it uses more materials and components.

Why Do King Size Adjustable-Air Mattresses Cost More?

1. Size and Materials

A king size mattress uses more fabric, foam, air chambers, and support materials than a queen or full. This directly affects cost. Many shoppers notice that:

• The jump from queen to king often comes with a notable price increase
• The jump from king to California king (where available) is usually similar or slightly more

2. Comfort and Support Features

Higher-priced series may offer:

• Thicker comfort layers or added cushioning
• More sophisticated support or zoning
• Extra design elements that improve pressure relief or airflow

These features are common reasons for price differences within the same brand.

3. Built-In Technology and Adjustability

Some adjustable-air mattresses include more advanced controls or integrated tech features. As these options become more complex, the overall cost of a king size in that series tends to go up.

What Else Affects How Much a King Size Adjustable-Air Mattress Costs?

Is the Base Included?

When people ask “How Much Is a King Size Sleep Number Mattress”, they sometimes mean mattress only, and sometimes they mean mattress plus base.

A few cost-related points to keep in mind:

• Adjustable bases (that raise your head or feet) are often priced separately
• A basic platform or foundation usually costs less than a motorized or feature-rich base
• The total you pay can change a lot depending on whether you include an adjustable base, frame, or headboard

Customization and Accessories

Your final price can increase if you add:

• Mattress protectors or toppers
• Specialty pillows
• Split king configurations, where each side adjusts independently

These extras can be helpful, but they also mean the total cost of your king size setup is higher than the mattress alone.

How Does the Price Compare to Other Mattress Types?

Many shoppers want to know whether a king size adjustable-air mattress is more expensive than other king options.

In general:

• Versus basic innerspring or simple foam mattresses, adjustable-air models are often higher priced, especially in premium series
• Versus more advanced hybrid or luxury foam mattresses, prices may be similar or somewhat higher, depending on features
• The key difference is adjustability: you’re paying, in part, for the ability to change firmness over time

This helps explain why “How Much Is a King Size Sleep Number Mattress” usually leads to a wider price range than many one-firmness king beds.

How Can I Estimate What I’ll Actually Pay?

To estimate your own cost, it helps to answer a few quick questions:

• Which series tier fits you? Entry-level, mid-range, or premium?
• Mattress only or full setup? Will you use your existing frame or buy a new base?
• Standard king or split king? Split options usually cost more due to additional components.
• Must-have features vs. nice-to-have? Fewer add-ons generally means a lower total.

By clarifying these points, the broad question “How Much Is a King Size Sleep Number Mattress” becomes a more specific estimate tailored to your situation.
