A full size Sleep Number bed typically costs about $1,100-$4,500 for the mattress, with many buyers paying around $2,500 before delivery or an adjustable base. The model, optional base, delivery, and local labor rates are the biggest reasons a final quote may differ.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Full mattress | $1,100 | $2,500 | $4,500 | Price varies by model and features |
| Adjustable base | $400 | $900 | $1,500 | Optional; depends on base type |
| Delivery and setup | $100 | $250 | $400 | Check current quote and service area |
| Mattress, base, and setup | $1,600 | $3,650 | $6,400 | Approximate combined budget |
What a full size Sleep Number mattress usually costs
For the mattress alone, a practical budget is $1,100-$4,500. Entry-level models generally sit near the lower end, while models with more cushioning, temperature features, or advanced adjustment controls can cost several thousand dollars. Promotions may reduce the checkout price, but prices and available models change.
For a typical full mattress without an adjustable base, plan on roughly $2,500 before taxes and delivery. A full mattress measures about 54 by 75 inches; the estimate assumes standard residential access and no unusual removal or setup work. Assumptions: U.S. retail pricing, full-size mattress, standard delivery conditions.
How mattress, base, and delivery charges shape the quote
A quote can combine the mattress with a foundation, adjustable base, delivery, and optional removal. Compare the written quote line by line: a low advertised mattress price may not include the support system or service charges. Sales tax depends on the delivery address and applicable local rules.
| Quote item | Typical range | Pricing basis | What changes it |
|---|---|---|---|
| Full Sleep Number mattress | $1,100-$4,500 | $1,100-$4,500 per mattress | Model, sale, included features |
| Adjustable base | $400-$1,500 | $400-$1,500 per base | Basic versus powered functions |
| Delivery and setup | $100-$400 | Per order | Distance, service tier, access |
| Old mattress removal | $0-$150 | Per mattress | Local availability and retailer policy |
| Taxes and accessories | $50-$500 | Varies by order | Local tax, protectors, bedding |
Delivery, base, and extras can add several hundred to more than $1,500 to the mattress price. Confirm whether delivery includes in-room placement, assembly, and removal; these services may be bundled or charged separately.
Which model features raise the full mattress price?
Model tier is the largest price driver. Compare the exact full-size model and its included features rather than relying on a brand-wide starting price. Added comfort layers, adjustable firmness controls, temperature-management features, and included accessories can move a mattress toward the upper end of the range.
Also check whether the quoted configuration is available in full size. Some features, packages, or promotions may apply only to selected sizes or models. Matching the model name, size, and included components on every quote prevents misleading price comparisons.
Does an adjustable base change the total substantially?
Yes. A full mattress on a basic compatible foundation costs less than a package with a powered adjustable base. A base may add roughly $400-$1,500, depending on features such as head or foot elevation and other controls. Existing foundations should be checked for compatibility before assuming they can be reused.
A frame or foundation is not always included in the mattress price. Ask whether the quote specifies a foundation, adjustable base, or neither, and confirm the dimensions and weight requirements. Reusing a compatible support can avoid a major add-on, but an incompatible base may affect setup or coverage.
How delivery distance and setup affect the final price
Delivery and installation commonly add about $100-$400, though the charge depends on the seller, service area, and delivery tier. Stairs, narrow hallways, long carries, or a remote address can affect service availability or create extra charges. Rural buyers should confirm the service boundary and any mileage or access fee before scheduling.
Setup time is usually shorter when the room is clear and the route is accessible. If the job includes removing an old bed or assembling a powered base, ask whether those tasks are included. Get a written list of included labor instead of treating delivery and installation as interchangeable.
Three full size purchase budgets with different equipment
A mattress-only purchase at $1,500 with $200 delivery comes to about $1,700 before tax. A midrange mattress at $2,500, a $900 adjustable base, and $250 setup total about $3,650 before tax. A premium mattress at $4,200, a $1,300 base, and $350 delivery totals roughly $5,850 before tax.
These examples use illustrative prices rather than guaranteed model quotes. Removal, bedding, and sales tax are excluded unless stated. For an apples-to-apples comparison, use the same mattress size, base type, delivery service, and removal choice for every seller.
Ways to lower the price without losing needed features
Compare the mattress-only price with a bundled package, then check whether the bundle discount outweighs the cost of components that are not needed. Choose the least expensive model that includes the desired comfort and adjustment features, and avoid paying for accessories that can be purchased separately for less.
Ask about current promotions, price matching, delivery fees, and removal charges before placing an order. If a compatible foundation is already available, include its condition and compatibility in the decision. Controlling the base and accessory choices is often more effective than sacrificing a feature that matters for everyday use.
