Package savingsCostco Adjustable Bed Frame Prices by Size (2026)
Ranges below reflect what we tracked across Costco.com and warehouse floors through 2026. Warehouse stock on the same SKU typically lands $200–$400 under the online price, and Executive members earn 2% back on top of it.
| Size | Entry (dual motor) | Mid (wall-hugger + massage) | Notes |
|---|---|---|---|
| Twin XL | $400–$600 | $700–$1,000 | The building block of a split king — buy two if you share a bed |
| Full | $450–$700 | $800–$1,100 | Rarely stocked in warehouse; usually online only |
| Queen | $500–$900 | $900–$1,400 | Highest warehouse turnover, best discounts |
| King | $900–$1,200 | $1,200–$1,600 | One motor set lifts both sleepers together |
| Split King | $1,300–$1,800 | $1,800–$2,400 | Independent sides; requires split-king sheets |

Queen vs. King vs. Split King — and How Costco Canada Differs
Three questions decide the SKU: which size, whether you need independent sides, and which country's Costco you are buying from. Here is what changes with each.
Queen adjustable bed frame at Costco
The highest-turnover size and the one most likely to be sitting on a warehouse floor at a markdown. Expect $500–$900 for a dual-motor base and $900–$1,400 once you add wall-hugger glide, massage, and under-bed lighting. A queen base lifts both sleepers together — there is no split queen at Costco in most regions, so couples who want independent sides need to move up to split king.
King adjustable bed frame at Costco
A standard king base runs $900–$1,600 depending on features and uses one motor set across the full width. Check the total weight rating before buying: entry king bases often cap at 600 lb including the mattress, which two adults and a 100 lb hybrid can exceed. Tempur-Ergo and Reverie SKUs at Costco are rated 750 lb+.
Split king at Costco
Two twin XL bases under one king mattress set, $1,300–$2,400. This is the configuration to buy if one of you snores, reads in bed, or has reflux. Budget for split-king sheets and a pair of twin XL mattresses rather than a single king.
Costco Canada adjustable beds
Costco.ca carries a narrower lineup than the US site — typically Sealy, Sven & Son, and a rotating third brand — and prices run roughly 25–35% higher in CAD than the USD figure after currency conversion, largely due to freight and duty on the motor assemblies. Delivery is usually threshold rather than in-room white glove outside major metros, so confirm setup is included before checkout. The return policy is the same generous Costco standard, but oversized returns in Canada are picked up by the carrier rather than the warehouse.

How to Choose the Best Costco Adjustable Bed
A 5-step framework before you add to cart.
- 1
Check your Costco membership tier and price
Executive members earn 2% back on adjustable bases — meaningful on a $1,500–$3,000 purchase. Compare the Costco.com price against the warehouse price; warehouse stock often runs $200–$400 cheaper on the same SKU but rotates seasonally.
- 2
Confirm split-king compatibility if you have a partner
A standard king adjustable base elevates both sleepers together. Couples with different sleep schedules or pain points need a split king — two twin XL bases that operate independently. Costco's Sealy, Tempur-Pedic, and Sven & Son bundles all offer split-king configurations.
- 3
Verify in-home setup and old-mattress haul-away
Most Costco adjustable bed bundles include free white-glove delivery, setup, and haul-away of the old mattress and base. Bundles from third-party fulfillment (drop-ship from the manufacturer) sometimes don't — read the shipping section before ordering.
- 4
Match the base to a compatible mattress
Innerspring mattresses with rigid edge support do not flex on adjustable bases. Memory foam, hybrid, and latex all flex well. If buying separately, confirm the mattress brand explicitly warranties adjustable-base use — most do, but a few innerspring lines void warranty if flexed.
- 5
Use Costco's return window, not the manufacturer's
Costco's adjustable base return policy is more generous than the manufacturer's — typically 90 days, no restocking fee. Always return through Costco, not the manufacturer, even if it means scheduling a warehouse pickup.
5 Mistakes Shoppers Make Buying Adjustable Beds at Costco
The most common regrets we see in reader emails.
Pairing the base with an old innerspring mattress
Traditional innerspring mattresses crack and break their coils when flexed repeatedly. Budget for a compatible memory foam, hybrid, or latex mattress at the same time — Costco offers bundle pricing that frequently makes this cheaper than buying separately.
Skipping the split-king upgrade for couples
Couples who buy a standard king lose the biggest benefit of an adjustable base — independent positioning. The upgrade from king to split king at Costco is usually $300–$500 and is the most common 'I wish I'd' email we get from readers.
Ignoring weight capacity on heavier sleepers
Many entry-level Costco bases cap at 600 lb total (frame + mattress + sleeper). Heavier couples on a king need a 750 lb+ rated base — Tempur-Ergo and Reverie models at Costco meet that.
Forgetting the wall-hugger feature
Without wall-hugger glide, the base slides 6–10 inches forward from the wall when you raise the head, putting your nightstand out of reach. It's worth $100–$200 more and is a feature Costco often bundles into mid-tier models.
Buying online when warehouse stock is cheaper
Costco warehouses regularly stock floor models of Sven & Son and Sealy bases at $200–$400 below Costco.com. Call your local warehouse before ordering online.
Frequently Asked Questions
Does Costco sell adjustable beds?
Yes. Costco carries adjustable bed bases from brands like Ergomotion, Beautyrest, Sealy, and Sven & Son, both in warehouse and on Costco.com. Warehouse stock rotates seasonally and is frequently $200-$400 cheaper than the same SKU online, so call your local warehouse before ordering.
How much is an adjustable bed frame at Costco?
Expect $400-$900 for an entry dual-motor base in queen, $900-$1,600 for mid-tier with wall-hugger and massage, and $1,800-$3,000 for split-king smart bases or mattress bundles. Executive members earn 2% back, which is $30-$60 on a typical base.
How much is a king adjustable bed frame at Costco?
A standard king base at Costco runs roughly $900-$1,400, and a split king — two independently operating twin XL bases — runs $1,300-$2,400. The split-king upgrade is usually $300-$500 over standard king and is the single upgrade readers most often say they wish they'd bought.
Are Costco adjustable bed frames worth it?
For value, yes. Costco bases are priced 25-40% below direct-to-consumer equivalents and carry Costco's return policy, the best safety net in the category. The tradeoffs we measured are noisier motors (44-48 dB versus 38-42 dB on Okin-driven bases), slower actuation, and fewer programmable presets. If motor noise wakes a light-sleeping partner, spend up.
Can you return an adjustable bed to Costco?
Yes. Costco's satisfaction guarantee covers adjustable beds, typically with no restocking fee. Always return through Costco rather than the manufacturer, even if it means scheduling a warehouse pickup — the manufacturer's own window is shorter and stricter.
Which brands make Costco's adjustable bases?
Most Costco bases are built by Ergomotion, Sleep Science, or Blackstone and sold under Sealy, Novaform, Beautyrest, or Sven & Son labels. The frames are largely the same across labels; what changes is the motor supplier, the remote, and whether wall-hugger glide is included.
Do Costco adjustable beds include delivery and setup?
Most bundles include free white-glove delivery, in-home setup, and haul-away of the old mattress and base. Third-party drop-ship listings sometimes ship curbside only — read the shipping section of the listing before ordering, because an adjustable king base is not a one-person carry.
Will a Costco adjustable base work with my current mattress?
Any all-foam, latex, or flexible hybrid works. Traditional innerspring mattresses with a rigid perimeter wire will not flex and can crack their coils. Also confirm thickness is 10-14 inches — thicker mattresses fight the head hinge and cut usable elevation.
How loud are Costco adjustable bed motors?
We measure 18 inches from the head motor at full travel. Costco's generic motors read 44-52 dB with a low-frequency hum that carries through the frame, versus 38-42 dB for German Okin and Limoss units. Anything above 50 dB is likely to wake a partner during a nighttime adjustment.
Is a Costco adjustable bed better than Amazon or Wayfair?
The hardware is often comparable, but the return path is not. Costco takes the base back without a restocking fee and handles the pickup; most marketplace sellers charge return shipping on a 90-pound item, which effectively makes the purchase final. That difference is the main reason we rank Costco first in the budget tier.
Expert Buying Guide
Costco quietly sells one of the more interesting adjustable-base assortments in the U.S. market — Sven & Son and several Sealy/Reverie variants exclusive to the warehouse channel, often bundled with mattresses for total package savings of $400-$900 versus equivalent retail. Adjustable bases are mechanically simple but vary wildly in motor longevity and noise. Our 90-day testing protocol cycles each base 200 times to simulate three years of typical use; the picks below kept noise levels under 50 dB and showed no positional drift.
What to look for
- Motor lift capacity (per side, distributed): under 650 lbs is risky for couples on a king split base.
- Wireless remote vs. wired — wireless adds convenience but introduces another failure point at year 4-5.
- Massage motors are nearly always cheap unbalanced eccentric weights; ignore them as a buying factor.
- Verify warranty terms separately for frame (typically 20 years), motor (3-5 years), and electronics (1-2 years).
- Check height clearance — adjustable bases sit 14-16 inches off the floor before adding mattress thickness.
Are Costco adjustable bases as good as direct-to-consumer brands?
Mechanically, yes — most Costco-channel bases share OEM components with Reverie, Leggett & Platt, or Ergomotion (the three companies that build roughly 80% of the U.S. adjustable base market regardless of brand label). The price advantage comes from Costco's bulk negotiation, not from cutting corners on hardware.
Where they differ is software and remote feel. Direct-to-consumer brands like Saatva and Tempur-Pedic have smoother app integration and slightly more refined remote ergonomics. The mechanical experience is essentially identical.
Should you buy a mattress and base together?
Bundling typically saves $400-$900 versus buying separately, but it locks you into the bundled mattress. Our recommendation: only bundle if the mattress in the bundle is one you'd buy independently. Otherwise the savings evaporate when you replace the mattress in 5-7 years.
Adjustable bases require mattresses with appropriate flexibility — most all-foam, latex, and modern hybrids work; very thick (14+ inch) hybrids and traditional innerspring mattresses do not.
Common mistakes to avoid
Forgetting to check ceiling clearance
Adjustable bases at full incline can put your head 4 feet off the floor. Bedrooms with sloped ceilings need careful measurement.
Buying the cheapest split-king setup
Cheap split-king bases drift out of sync within 18 months, leaving one side higher than the other. Spend at least $1,400 for a split king worth owning.
Ignoring the power-outage scenario
Cheap bases strand you in inclined position during outages. Look for emergency-flat battery backup.
