A king size adjustable bed typically costs $1,200-$5,500, with many complete frame-and-mattress packages averaging $2,800. Price depends on whether the bed is a standard king or split king, the frame’s features, mattress compatibility, and delivery or setup fees.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| King adjustable base | $800 | $1,800 | $4,000 | Frame only; features affect price |
| King mattress | $500 | $1,300 | $3,000 | Compatible foam or hybrid models |
| Complete bed package | $1,200 | $2,800 | $5,500 | Base and mattress, before some fees |
| Delivery and setup | $0 | $150 | $400 | May be included or charged separately |
King adjustable bed prices by package type
A basic king adjustable base alone generally runs $800-$1,500. A midrange base with a compatible mattress usually brings the total to $2,000-$3,500, while premium packages with advanced positioning, massage, and upgraded mattresses can reach $4,000-$5,500 or more.
These estimates assume a new, standard king-size setup with ordinary access and no custom furniture changes. A split king uses two independently adjustable halves and may cost more, particularly when each side has its own mattress and controls. Assumptions: U.S. retail pricing, standard delivery access, no major sale or custom installation. For most buyers, the complete base-and-mattress package—not the frame-only price—is the useful budget comparison.
What the adjustable base, mattress, and setup add
Quotes can bundle costs differently, so buyers should check whether the listed price includes the mattress, delivery, and removal of an old bed. These typical component ranges apply to a king setup.
| Cost component | Typical range | What changes the charge | Pricing basis |
|---|---|---|---|
| Adjustable base | $800-$4,000 | Motors, lift capacity, presets, massage | Per king base |
| Compatible mattress | $500-$3,000 | Foam or hybrid construction, materials | Per king mattress |
| Delivery and setup | $0-$400 | In-home assembly, stairs, distance | Per delivery |
| Old-bed removal | $50-$200 | Hauling distance and disposal rules | Per item |
| Accessories | $30-$300 | Retainer bars, legs, compatible frame | Per accessory |
Setup labor may be included in white-glove delivery or billed separately. Where charged by time, a two-person crew for 1-2 hours at roughly $75-$125 per worker-hour can add $150-$500; this is a planning estimate, not a universal retailer rate. Ask for an itemized quote that separates the base, mattress, delivery, assembly, and disposal.
How king versus split king changes the quote
A standard king measures about 76 by 80 inches and typically uses one adjustable platform. A split king consists of two twin XL sides, each about 38 by 80 inches, which can move independently. The split configuration often adds $200-$800 for the second adjustable base or upgraded dual-control features; the exact difference depends on whether the package includes two bases or a linked system.
Split king bedding can also cost more: separate fitted sheets and specialty mattress protectors may add $50-$250 compared with standard king bedding. A split setup is not automatically more expensive if a retailer prices a two-base bundle competitively. Compare the number of independently moving bases, not just the label “king” on the package.
Which mattress materials work with a powered king base?
Foam and many latex mattresses generally flex well with an adjustable base, while some hybrids are designed for bending too. A compatible king mattress commonly costs $700-$2,000 for foam or $1,000-$2,800 for a hybrid, with premium materials and thicker builds increasing the price. Innerspring models with rigid interconnected coils may not flex properly and can void warranty coverage.
Check the mattress maker’s compatibility rules, maximum thickness, and warranty before reusing an existing mattress. A mattress that is too rigid or heavy can limit movement or strain the mechanism. Replacing a mattress that is still compatible can add more to the budget than upgrading the base itself.
Delivery, stairs, and labor can raise installation charges
Free threshold delivery may leave assembly to the buyer; room-of-choice delivery and setup commonly cost $100-$300 when not included. Stair carries, narrow hallways, remote delivery areas, or an old bed that needs dismantling can add roughly $50-$200, depending on the retailer and local service terms. Confirm whether packaging removal is included.
Most straightforward installations take about 1-2 hours with two workers. A bedroom with difficult access or furniture that must be moved can take longer. Measure the doorway, stairwell, and route to the bedroom before delivery to avoid a failed-delivery or extra-labor fee.
Regional delivery rates vary across U.S. markets
Retailer promotions and local labor availability can shift the delivered price. Large metro areas may run about 5%-15% above a national baseline for setup or specialty delivery, while rural addresses can face a 10%-25% surcharge or limited service windows. These are planning ranges; a retailer’s stated delivery zone and quote determine the actual fee.
Local sales tax also changes the checkout total, often adding several percent based on the delivery address. Compare final totals from sellers that offer the same base features and mattress, rather than comparing advertised prices alone. Check tax, delivery, setup, and old-bed removal together before choosing the lowest quote.
Three king-bed quotes show realistic package totals
| Example setup | Base and mattress | Delivery and setup | Estimated total |
|---|---|---|---|
| Basic standard king, foam mattress | $1,400-$2,100 | $0-$150 | $1,400-$2,250 |
| Midrange split king, two adjustable sides | $2,700-$3,900 | $100-$300 | $2,800-$4,200 |
| Premium king, hybrid mattress, massage | $4,000-$5,500 | $150-$400 | $4,150-$5,900 |
These examples assume standard residential delivery and exclude sales tax, financing charges, and optional old-bed hauling. A promotion may lower the package price, but included accessories or mattress tiers can differ. Use the exact model numbers and included services to make competing quotes comparable.
Ways to lower the price without losing needed features
Choose only functions that will be used: head and foot elevation are core features, while massage, app controls, under-bed lighting, and programmable presets can add hundreds of dollars. A standard king may also cost less than a split king if independent movement is not necessary. Keep a compatible mattress rather than replacing it solely to match a bundle.
Compare sale pricing with the regular delivered total, ask whether setup is included, and check whether the frame warranty covers motors and labor separately. Avoid paying for a furniture-style surround or adjustable-compatible headboard unless it is needed for the room. Controlling the feature list and delivery scope usually saves more than choosing the cheapest base without checking compatibility.
