How Much Does a King Size Sleep Number Bed Cost? A Practical FAQ Guide
If you’re asking “How Much Does a King Size Sleep Number Bed Cost”, you’re usually trying to figure out a realistic price range, what makes the cost go up or down, and whether any extras are worth it. This FAQ-style guide walks through the typical factors that affect pricing so you can estimate what you might pay and why.
What is a “Sleep Number–style” bed, and why does it cost more?
When people ask “How Much Does a King Size Sleep Number Bed Cost”, they’re usually referring to an adjustable air mattress system that lets each side of the bed change firmness independently.
These beds tend to cost more than basic mattresses because they typically include:
- Adjustable air chambers instead of a fixed foam or spring core
- Electronic firmness controls, often with a remote or app
- More complex construction, sometimes including foam layers and edge support
- Optional bases that raise the head/feet or add extra features
In short, you’re paying for customizable firmness and more components, not just a simple mattress.
What is the typical price range for a king size adjustable air bed?
Prices vary widely, but a king size adjustable-air mattress system (mattress only) often falls into the mid to high price range of the mattress market.
In general, many shoppers find that:
- A basic king mattress (without electronics or air systems) can be in a lower price range, depending on materials.
- A king adjustable air bed commonly costs more than many traditional innerspring or foam mattresses, largely due to the adjustable technology and dual-zone design.
The total cost can change significantly depending on:
- Whether you choose mattress only or mattress + adjustable base
- The specific series or model level (entry, mid-range, premium)
- Any added features, like extra comfort foam, smart controls, or integrated bases
Which factors affect the cost the most?
1. Mattress series or model level
Most adjustable-air brands group products into tiers:
- Entry-level models: Simpler construction, fewer foam layers, basic controls
- Mid-range models: More comfort materials, more zones, sometimes upgraded fabric
- Premium models: Thicker profiles, extra cushioning, more advanced adjustability or features
Higher tiers typically mean a higher king-size price.
2. Mattress thickness and materials
Thicker mattresses with multiple comfort layers (foam, pillow-top style, or support enhancements) usually cost more than slimmer, simpler designs.
3. Adjustable base vs. flat foundation
A major cost difference comes from whether you buy:
- Mattress only (often the lower total cost)
- Mattress + simple foundation (still relatively moderate)
- Mattress + full adjustable base (usually the highest total price)
An adjustable base that lifts the head or feet, and especially one with advanced features, often adds a significant amount to your final spend.
4. Size: Standard King vs. Split King
When shoppers ask how much a king costs, they may mean:
- Standard king: One large mattress
- Split king: Two separate mattresses side by side, often on two adjustable bases
A split king setup frequently costs more than a one-piece king, because you’re effectively buying more components.
What extra costs should shoppers keep in mind?
Beyond the sticker price, people researching “How Much Does a King Size Sleep Number Bed Cost” are often surprised by additional expenses, such as:
- Delivery or setup fees (often higher for adjustable bases)
- Removal of old mattress, if not included
- Specialty sheets for split king or thicker profiles
- Extended coverage plans, if chosen
These extras can make the real-world cost a bit higher than the base mattress price alone.
Is a more expensive king model always better?
Not necessarily. Higher price does not automatically mean better sleep for every person. Often, the best value comes from matching features to your actual needs, such as:
- Whether you truly use advanced adjustability or just need basic firmness changes
- How important added foam layers or plush tops are to your comfort
- Whether a split king is necessary or a standard king is sufficient
For many shoppers, a mid-range king adjustable air bed can feel like the best balance of features and price.
