Quick Answer
Costco sells adjustable bases from Blackstone and Beautyrest priced between $400 and $1,200, but not every mattress works well on an adjustable frame. Memory foam and latex mattresses flex properly, while innerspring models with traditional coils can be damaged by repeated bending. Call (519) 770-0001 for a guided fitting.
Brad, Owner, 40+ years of experience: "We have been helping Brantford families sleep better since 1997. Every customer gets personal attention, honest advice, and the kind of follow-up service you just do not get from big box stores."
Adjustable bases have gone from hospital equipment to mainstream bedroom furniture. The appeal is obvious, elevate your head for reading or watching TV, raise your feet to reduce lower back pressure, and find that perfect zero-gravity position for sleeping. Costco has jumped on the trend with several adjustable base options, but there's a critical question most shoppers overlook: will your mattress actually work on one?
Costco's Adjustable Base Options in Canada
Blackstone Adjustable Base
Price: $399-$599 (queen) | Features: Head and foot elevation, wireless remote, USB ports
Available seasonally in-warehouse and online
Beautyrest Advanced Motion Base
Price: $799-$1,199 (queen) | Features: Head/foot adjustment, massage, programmable positions, Bluetooth
Typically online-only through costco.ca
Costco Adjustable Base + Mattress Bundles

Limited selection, availability varies by season
The bases themselves are reasonably well-built for the price. The bigger issue is what you put on top of them.
Which Mattresses Work on Adjustable Bases?
| Mattress Type | Compatible? | Notes |
|---|---|---|
| Memory foam | Yes | Flexes easily, ideal for adjustable bases |
| Latex | Yes | Naturally flexible, excellent pairing |
| Individually wrapped coils | Usually yes | Pocketed coils flex independently; check manufacturer specs |
| Traditional innerspring | No | Bonnell coils are rigid; bending damages the support system |
| Hybrid (foam + coils) | Usually yes | Most modern hybrids are designed for adjustable bases |
| Pillow top innerspring | Risky | Thick pillow top can bunch when bent; may void warranty |

Common Mistakes When Buying Adjustable Bases at Costco
Mistake 1: Buying the base and mattress separately without checking compatibility.
Not all mattresses sold at Costco are adjustable-base compatible. Some of their innerspring models use traditional coil systems that shouldn't be repeatedly bent. Always verify before purchasing.
Mistake 2: Ignoring mattress height and weight.
Adjustable bases have weight limits. A 14-inch, 100-pound king mattress on a base rated for 80 pounds will strain the motors and shorten the base's lifespan. Costco's bases typically handle standard mattresses, but check the specs if you're buying a particularly thick or heavy model.
Mistake 3: Not testing the combination in person.
How a mattress feels on a flat surface is different from how it feels on an adjustable base. The bending changes pressure distribution and can affect firmness perception. You really need to test the pairing before committing.
What to Look For in an Adjustable-Base Mattress
Key Features
- Flexible coil system Individually wrapped coils bend independently without damaging the support structure
- Moderate profile 10-13 inches is the sweet spot; thicker mattresses resist bending and stress motors
- Quality comfort layers Higher-density foams maintain their shape even when the mattress is articulated
- No rigid border wire Some innerspring mattresses have a steel border rod that prevents proper flexing
- Manufacturer approval Check that the mattress warranty covers use on adjustable bases

Restonic Mattresses on Adjustable Bases
Brad, our senior mattress consultant at Mattress Miracle, frequently helps customers pair Restonic mattresses with adjustable bases: "Every Restonic model we carry uses individually wrapped coils that flex beautifully on adjustable bases. The ComfortCare with its 1,222 coils actually performs better on an adjustable base than most mattresses because each coil responds independently to the change in angle."
Top Restonic Picks for Adjustable Bases
- Restonic ComfortCare (Queen $1,619) 1,222 individually wrapped coils, flexible construction, excellent value for adjustable base use
- Restonic Revive Reflections ET (Queen $2,395) 1,200 coils, dual-sided flippable design that works on adjustable bases in both orientations
- Restonic Luxury Silk & Wool (Queen $2,395) 884 zoned coils, premium comfort layers that maintain shape during articulation
All Restonic mattresses at Mattress Miracle come with a warranty that explicitly covers adjustable base use, something not all brands guarantee, especially at Costco's price points.

Call 519-770-0001Can I use any Costco mattress on an adjustable base?
No. Traditional innerspring mattresses with Bonnell coils or rigid border wires should not be used on adjustable bases. Memory foam, latex, and most pocketed-coil models are compatible, but always check the specific mattress warranty to confirm adjustable base use is covered.
Does Costco sell adjustable base and mattress bundles?
Yes, Costco occasionally offers bundles that include an adjustable base and compatible mattress. These are typically available online through costco.ca and occasionally in-warehouse. The selection is limited compared to buying separately, but the bundled pricing can offer savings of $200-$400 versus buying each piece individually.
Will an adjustable base void my mattress warranty?
It depends on the mattress brand. Some manufacturers specifically exclude adjustable base use from warranty coverage, meaning any damage from bending isn't covered. Always check the warranty fine print. All Restonic mattresses at Mattress Miracle are warranted for use with adjustable bases.
How much does a good adjustable base cost?
Quality adjustable bases range from $400 to $2,000+ depending on features. Basic models with head and foot elevation start around $400-$600. Mid-range bases with massage, programmable positions, and USB ports run $800-$1,200. Premium bases with under-bed lighting, sleep tracking, and anti-snore features can exceed $2,000.
Do adjustable bases work with bed frames?
Most adjustable bases can sit inside a standard bed frame, on a platform frame, or stand on their own legs. However, the base needs clearance to articulate properly. If your current bed frame has side rails, make sure the adjustable base can move freely within them. Some customers place the adjustable base directly on the floor for a lower profile.
Is a split king adjustable base better for couples?
Split king adjustable bases let each partner control their side independently, one person can elevate their head while the other sleeps flat. This is ideal for couples with different sleep preferences, snoring issues, or health conditions requiring elevation. The trade-off is a seam down the middle and higher total cost (two twin XL mattresses plus two bases or one split base).
What headboards work with an adjustable base, and how do they attach?
Most freestanding or wall-mountable headboards work with an adjustable base - the headboard stays still while the mattress section moves up and down beneath it. The two compatibility checks: standard 22-30 inch hardware-mount hole spacing on the headboard (matches most brackets shipped with adjustable bases), and enough vertical clearance that the mattress doesn't strike the headboard at full elevation. Built-in panel-bed headboards (welded to a sleigh-style frame) generally don't transfer to adjustable bases. The Canadian Chiropractic Association notes that head-of-bed elevation is a recommended posture for managing GERD and snoring; research published in Sleep & Breathing (Souza et al., 2017) found 7.5-degree head elevation reduced apnea-hypopnea index from 15.7 to 10.7 events per hour (about 31%) in OSA patients without disrupting sleep architecture - meaning the elevation needs to actually go that high, which means any decorative surround needs to clear the head section at full elevation. Talia, on our showroom floor, walks adjustable-base shoppers through this in our showroom: bring a photo and rough measurements of the existing headboard, and she can usually confirm fit in under a minute. For a frame that integrates the headboard from the start, our King Elora Platform Bed Frame with Adjustable Headboard is purpose-built for the combination. Browse the adjustable bed frame collection for compatible options. For broader adjustable buying context see our cornerstone adjustable beds Canada guide.
What is the Lifestyle adjustable base, and how does it compare to the bases Costco sells?
"Lifestyle" in adjustable bases refers to the Lifestyle by Leggett & Platt line - one of the largest North American adjustable base manufacturers. Their PowerLift bases offer 600 to 850-pound lift capacity, wall-hugger engineering (which keeps you within reach of your nightstand at full elevation), zero-gravity preset, dual massage, and a programmable favourite-position button. Warranty is typically a structure of 1-year full service, parts coverage to year 5, and lifetime limited on the frame. Costco sells a range of adjustable bases, mostly under their own bundles or under the Sven & Son and Tempur-Pedic Ergo lines, with similar feature sets at similar pricing ($899 to $2,499 for queen). The Canadian Chiropractic Association notes that adjustable bases can help relieve back pain by allowing the head and knees to elevate slightly, which reduces lumbar pressure during sleep, regardless of brand. Talia, who fits Brantford customers with adjustable bases, says: "Lifestyle bases are well-built and the wall-hugger feature really matters if your headboard or nightstand is close to the bed. The Costco bundles can be a deal but check whether the warranty is honoured by a local technician or if you have to ship the base back."
