A Sleep Number P6 king mattress typically costs about $3,500-$4,700 before delivery, a base, or accessories; the midpoint is roughly $4,100. The final price depends most on current promotions, whether the purchase includes an adjustable base, and delivery or setup charges.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| P6 king mattress | $3,500 | $4,100 | $4,700 | Mattress only, before tax |
| Delivery and setup | $0 | $200 | $300 | Promotions and location affect fees |
| Adjustable base | $1,200 | $2,300 | $4,000+ | Price varies by base model and features |
| Mattress and base package | $4,700 | $6,400 | $8,700+ | Before tax; discounts may apply |
Assumptions: U.S. king mattress, typical retail pricing, standard delivery, and no unusual access or foundation work.
What a King P6 Mattress Usually Costs
For the P6 king mattress alone, a practical shopping range is $3,500-$4,700. A typical undiscounted or lightly discounted quote lands near $4,100, though limited-time offers can reduce the checkout price. Retail prices and promotions change, so shoppers should compare the current mattress-only price with the package price rather than relying on an old advertised figure.
Budget about $4,100 for the mattress, then add delivery, tax, and any base or frame needed. A king P6 is a split-firmness air bed: each side can be adjusted independently, but the mattress is sold as one king-size unit. State and local sales tax can add several hundred dollars at this price.
Where the King P6 Quote Goes: Mattress, Base, Delivery
The mattress is usually the largest expense. A base is a separate decision: a compatible adjustable base can substantially increase the total, while an existing supportive bed frame may avoid that purchase. Confirm compatibility and the required foundation before ordering.
| Quote item | Typical price | What changes the amount | Cost note |
|---|---|---|---|
| P6 king mattress | $3,500-$4,700 | Sale, retailer, bundle | Core mattress purchase |
| Adjustable base | $1,200-$4,000+ | Elevation, massage, preset features | Optional, sold separately |
| Delivery and setup | $0-$300 | Promotion, distance, service tier | Check the quote for included setup |
| Removal of old mattress | $0-$150 | Local service availability | May be priced separately |
| Tax and accessories | $100-$800+ | Tax rate, sheets, protector | Depends on location and choices |
Assumptions: Broad U.S. retail ranges; base pricing reflects entry through higher-feature adjustable models.
How Split King Setup and Adjustable Bases Change the Total
A standard king P6 allows separate firmness settings on the left and right sides without being two separate mattresses. A split king package instead uses two twin XL mattresses and may require a split-compatible base. Ask whether the quoted P6 configuration is one king mattress or two pieces, and whether the base supports the selected arrangement.
Adding an adjustable base can bring a mattress-and-base purchase to roughly $4,700-$8,700 or more before tax. The exact package discount matters: compare the standalone mattress and base prices against the bundled quote, and verify that the bundle includes the particular base model, delivery, and setup.
Base features—not just mattress size—can shift the total by several thousand dollars.
Which P6 Features Affect the King Price Most?
Promotional timing and package choices usually matter more than small accessory differences. Mattress-only versus adjustable-base pricing is the largest scope change; premium base functions can add another $1,000-$2,000 or more compared with a basic adjustable model. Delivery can also differ by ZIP code and service level.
For a split king, the two-mattress configuration may cost differently from a single king setup, especially when paired with a split adjustable base. Confirm the exact product configuration and the number of included remotes or other components. A quote that says “king” alone may not make the setup clear.
Assumptions: Price differences are estimates, not guaranteed manufacturer surcharges; retailer packages and discounts vary.
Delivery, Setup, and Old-Mattress Removal Fees
White-glove delivery may include bringing the mattress indoors, assembly, and setup, but included services differ. A common planning allowance is $0-$300 for delivery and setup, with old-mattress removal potentially adding $0-$150 where offered. Stairs, long carries, restricted access, or a remote delivery area can affect availability or charges.
Confirm whether the delivery team assembles the adjustable base, connects the bed, and removes packaging. Ask for the total service charge in writing, including any fee for the old mattress. Delivery details can turn an attractive online price into a higher final checkout total.
How Long Does a King P6 Purchase Take to Install?
For a clear path into the bedroom and a standard setup, delivery and assembly commonly take about 1-2 hours on site. A two-person team may assemble the base, position the mattress, and check its controls. The purchase process can take longer if a specific model or base is backordered or delivery appointments are limited.
Labor is often included in a delivery package rather than billed by the hour. For comparison only, independent furniture or bed assembly labor may run about $75-$125 per hour, but confirm that a third-party installer can handle the product correctly before hiring one.
Example: 2 hours × $75-$125 per hour equals $150-$250 if labor is billed separately.
King P6 Versus C-Series and Adjustable Base Packages
A lower-priced Sleep Number model may reduce the initial mattress bill, while a higher-tier model or more feature-rich adjustable base raises the package total. Compare the P6 with a C-series option at the same size and with the same base, delivery, and setup. Otherwise, a lower advertised price may reflect a different configuration rather than a direct equivalent.
Also compare what each quote includes, such as comfort layers, warranty terms, and trial or return conditions. A more expensive package is not automatically a better value if the buyer does not need its base features. Compare like-for-like king configurations and the final delivered total.
How to Lower the P6 King Price Without Losing Core Features
Track the mattress-only price and package price during major sale periods, then request an itemized quote. If the existing frame is compatible, skipping a new adjustable base is the largest possible saving. Avoid paying for premium base features unless they are useful, and check whether delivery, setup, or removal is already included before adding services.
Compare at least two current quotes for the same P6 king configuration, including tax and fees. Ask whether a package discount applies to the base or accessories, and whether a lower-cost delivery option is available. Keeping the scope to the mattress and necessary setup protects the budget without changing the P6 model.
