A split king adjustable bed setup typically costs $1,800-$6,000, with many buyers paying about $3,500 for two adjustable bases and two Twin XL mattresses. The final price depends on base features, mattress type, delivery, setup, and whether the existing bed frame or headboard needs changes.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Two adjustable bases | $900 | $1,800 | $4,000 | Pair of Twin XL bases, before premium features |
| Two Twin XL mattresses | $700 | $1,500 | $3,500 | Foam, hybrid, or specialty models |
| Delivery and setup | $0 | $150 | $400 | May be included or charged separately |
| Complete split king setup | $1,800 | $3,500 | $6,000 | Two bases, two mattresses, and typical delivery |
Assumptions: U.S. pricing for a standard split king with two Twin XL sides, midrange products, and no major bedroom modifications.
Typical split king bed prices by setup
For two bases and two mattresses, a practical budget is $1,800-$6,000, with about $3,500 representing a common midrange purchase. A basic setup may pair simple adjustable bases with entry-level foam mattresses. A higher-priced configuration may include independent head and foot lift, lumbar adjustment, massage, under-bed lighting, premium mattresses, and in-home installation.
Two Twin XL mattresses make the standard split king width of about 76 inches and length of about 80 inches. The two sides adjust independently, so partners can choose separate positions and mattress firmness. Prices generally apply to the pair; a quote for just one Twin XL base or mattress will not cover the full bed.
Base-only pricing commonly runs $450-$2,000 per Twin XL unit, or $900-$4,000 for the pair. Mattress pricing is often $350-$1,750 per Twin XL, or $700-$3,500 for two. The total can exceed $6,000 when buyers choose luxury mattresses, high-capacity bases, specialty upholstery, or extensive delivery services.
Retail bundles may cost less than buying each piece separately, but bundle contents differ. A low advertised price may cover bases only, exclude mattresses, or require customers to collect the products. Check whether the quote includes two bases, two compatible mattresses, remotes, delivery, setup, and applicable sales tax.
What two bases, mattresses, and delivery add to the quote
The biggest line items are the adjustable bases and mattresses; installation and accessories usually matter less unless the room needs special handling. The following ranges reflect a pair of Twin XL items and typical U.S. retail pricing rather than a fixed national rate.
| Quote component | Low | Typical | High | What changes the price |
|---|---|---|---|---|
| Two adjustable bases | $900 | $1,800 | $4,000 | Lift motors, massage, presets, capacity |
| Two Twin XL mattresses | $700 | $1,500 | $3,500 | Foam, hybrid coils, cooling layers, brand |
| Delivery and room setup | $0 | $150 | $400 | Threshold delivery versus in-home assembly |
| Frame or headboard hardware | $0 | $100 | $350 | Compatibility, brackets, retainer bars |
| Old bed removal | $0 | $75 | $200 | Haul-away availability and local fees |
Some retailers include delivery in the advertised price, while others charge for carrying the bases upstairs, assembling them, or removing packaging. Ask whether the delivery crew will connect both bases, test the remotes, and place the mattresses. A basic installation may take less than an hour; stairs, narrow hallways, or a long carry can increase the charge.
Accessories such as sheets made for split king beds, mattress retainers, or a connector kit may add $30-$200. A split king fitted sheet set often costs more than ordinary king bedding because each side has its own fitted sheet. If the bases sit inside an existing bed frame, confirm the required dimensions and bracket compatibility before purchase.
How lift features and mattress thickness change pricing
Feature upgrades can add hundreds or thousands of dollars to the pair, so the base model and mattress construction deserve separate comparisons. A basic adjustable base typically changes the head position and may raise the feet. More expensive units can add preset positions, programmable memory, massage motors, USB ports, lighting, lumbar support, or wall-hugging movement.
A base with head and foot articulation often falls around $450-$1,000 per Twin XL. Models with added lumbar adjustment, massage, or advanced remote controls may run $900-$2,000 per side. Confirm whether a feature operates independently on both sides and whether the price is for one base or the pair.
Mattress compatibility is another price consideration. Foam and many hybrid mattresses are designed to flex, but not every innerspring model is suitable for repeated adjustment. Two basic foam mattresses can cost $700-$1,200 together; midrange foam or hybrid pairs often cost $1,200-$2,400; premium or specialty models can reach $3,500 or more.
Mattress thickness, weight, and flexibility affect how well a setup moves. A thick mattress may limit articulation or require deeper-pocket sheets, while a heavy mattress may approach the base’s weight capacity once sleepers are included. Check the manufacturer’s maximum mattress thickness and load rating rather than assuming every king mattress fits.
Base capacity varies by model, but a common rating is roughly 600-850 pounds per side, including the mattress and occupants. For sleepers or mattresses that bring a side near its stated limit, a reinforced base may cost more but can be necessary. The relevant comparison is the maximum load per Twin XL unit, not the combined capacity of both sides.
Regional delivery rates and labor for bedroom setup
Regional differences usually affect delivery and installation more than the factory price of a base or mattress. Prices in major coastal cities and high-cost metro areas can be about 10%-20% above a lower-cost rural or Midwestern market, particularly when labor, stairs, and disposal are involved. That difference is not universal; retailer promotions and local competition can narrow it.
In-home setup may be included with a premium bundle or billed at $100-$250 for a straightforward delivery. A third-party furniture crew may charge around $75-$125 per hour, often with a minimum visit charge. A one-hour appointment could therefore cost $75-$125 before travel or service fees, while a more involved carry and assembly may require two workers for 1-2 hours.
Rural addresses can have delivery surcharges of roughly $50-$200 when the home lies outside a retailer’s normal service area. Apartments with elevator reservations, narrow stairwells, or limited parking can also affect the quote. Ask for the delivered price to the bedroom, not just the price to the curb or front door.
Delivery windows can be longer for less common configurations, including split king bases with specialized fabrics or high-capacity ratings. Rush delivery may add $50-$200 where offered. A delay is not automatically a cost, but it can become one if a separate installer or moving crew must make another appointment.
Three realistic budgets for a complete split king
These examples show how product choices and service level shift the total while keeping the standard two-base, two-mattress configuration. Actual retailer quotes may combine the line items differently, and local tax is excluded from each example.
| Example | Specifications | Product and labor estimate | Total |
|---|---|---|---|
| Budget bedroom | Two basic bases at $475 each; foam mattresses at $375 each; curbside delivery | $1,700 products + $50 delivery | $1,750 |
| Midrange couple | Two feature-rich bases at $850 each; hybrid mattresses at $700 each; room setup | $3,100 products + $175 setup | $3,275 |
| Premium setup | Two advanced bases at $1,650 each; premium mattresses at $1,500 each; removal and setup | $6,300 products + $350 services | $6,650 |
The budget example assumes no massage or premium mattress construction. The midrange example includes common convenience features, while the premium case includes high-end equipment and mattresses that push the price above the typical range. A quote that is far below these examples may omit mattresses or in-home service, so compare the included items rather than the headline figure.
Split king versus king mattress and adjustable alternatives
A split king generally costs more than a single king mattress setup because it requires two bases and two mattresses. A conventional king mattress and fixed foundation may cost about $800-$3,000 together, while a split king with adjustable bases commonly totals $1,800-$6,000. The extra expense buys independent movement and separate mattress choices.
Two Twin XL mattresses on a fixed foundation can provide different firmness levels without adjustable movement. That arrangement may cost roughly $700-$3,500 for the mattresses and foundation, depending on construction. It is a lower-cost alternative when independent head and foot lift is not essential.
A single king adjustable base with one king mattress can cost less than a split setup, but it does not provide independent positioning for each sleeper. A king base paired with two Twin XL mattresses may not work as intended unless the base is built for that arrangement. Verify manufacturer compatibility and the retailer’s return policy before mixing sizes.
Some buyers consider buying one adjustable side and keeping the other side fixed. A single Twin XL adjustable base may cost $450-$2,000, but the resulting bed may require custom framing or create a height difference. It is worth checking the cost of suitable side-by-side support before treating a one-sided upgrade as a simple half-price option.
Extra charges for old-bed removal and room access
Removal, access, and frame changes can turn an attractive equipment price into a higher delivered total. Haul-away commonly costs $75-$200 when available, and some retailers do not remove existing beds at all. Local disposal rules, mattress recycling programs, or building policies can affect both availability and fee.
Most two-piece bases can be carried separately, but the packaged components still need to fit through doorways and stairwells. Before delivery, measure the narrowest hallway, stair turn, and bedroom entrance. A return visit caused by blocked access may carry a fee, and special handling can add $50-$200 depending on the delivery provider.
Existing frames can require brackets or retainer bars to keep the bases positioned. Hardware and minor modifications may cost $30-$350, while replacing an incompatible bed frame can add considerably more. Do not assume a decorative headboard will attach directly to the adjustable bases; ask whether brackets are included and whether installation affects the warranty.
Sales tax depends on state and local rules, and delivery or installation may be taxable in some locations. For example, a $3,500 taxable purchase in a location with 7% sales tax adds $245. Request an itemized total that shows product prices, delivery, setup, accessories, haul-away, and tax.
How to lower the split king price without losing useful features
The clearest savings come from comparing complete packages and paying only for features that will be used. Get at least three itemized quotes for the same two Twin XL bases and mattress types. Compare the pair price, per-side price, included delivery, return terms, warranty, and any required accessories.
Choose the base functions that match actual needs. Head and foot articulation may be enough for many households; massage, app controls, lighting, and lumbar adjustment can raise the price without improving basic positioning. If only one sleeper wants premium adjustments, compare a split configuration with different bases rather than automatically buying two identical top-tier units.
Consider a midrange mattress rather than paying a premium for features unrelated to articulation. Confirm that the selected mattress is approved for adjustable use and that both sides can have different firmness levels if desired. A sale on a base-only bundle can be misleading if compatible mattresses and delivery later erase the savings.
Keep the existing bed frame if the bases fit securely and the manufacturer permits that installation. Handle simple room preparation and old bedding disposal independently, but do not disassemble or modify equipment in a way that voids the warranty. Bundling bases, mattresses, and delivery may reduce the total, though separate quotes can reveal whether the bundle discount is genuine.
Check whether the quote includes a trial period, return pickup, and warranty coverage for motors and electronics. A cheaper base with a short warranty may not be the lowest-cost choice if a failed motor requires paid service. For paid setup, estimate labor as 1-2 hours multiplied by the quoted crew rate, then add delivery and any minimum service fee.
