Key Takeaways for Split Queen Assembly
- A split queen adjustable bed uses two independent twin-XL bases that must be assembled and wired correctly so both sides work as intended.
- Careful cable routing, matching leg heights, and installing the centre connector bracket prevent drift, noise, and uneven sleeping surfaces.
- Each base needs its own power outlet and remote pairing, and the Leva app can link both sides for shared presets like zero-gravity or anti-snore.
- Following the process outlined below supports a reliable setup in under two hours.
- Prefer professional assembly? Browse split queen packages with optional white-glove setup in select provinces.
What You Need Before You Start
Leva Sleep ships every split queen package with the tools required for assembly. Before opening the cartons, confirm you have the following on hand:
- A clear floor space large enough for both bases with room to walk around them
- A grounded household outlet within reach of each base
- The included hex wrench or leg-attachment tool stored inside the base carton
- A second person to help flip and position each base safely
- A smartphone with Bluetooth enabled for Leva app pairing
No additional tools are required. Do not use power drills on leg hardware, because hand-tightening to the resistance point protects the threads.
Step 1: Unpack Both Cartons in the Bedroom
[Leva Split Queen Assembly – Step 1]
Lay both cartons flat in the room where the bed will stay. Slide each base out without lifting by the motor housing. Lay the bases face-down on the floor and locate the hardware bag taped to the underside of each frame.
Check legs, retainer brackets, power cords, sync cable, and remotes against the packing list before you move on. This quick inventory prevents mid-assembly surprises.
Common Mistake: Carrying a base upright before legs are attached can stress the motor bracket. Keep both bases horizontal until Step 4.
Step 2: Attach the Legs at Matching Heights
[Leva Split Queen Assembly – Step 2]
Thread each leg clockwise into its socket by hand until snug, then tighten a quarter-turn with the included hex wrench. Choose the leg height that lines up with your existing bed frame or headboard before you secure the legs.
Matching the height to your furniture keeps the base aligned and comfortable to use. Both bases must use the same leg height so the sleeping surface stays level across the full queen width.
Common Mistake: Mixing leg heights between the two bases creates a ridge at the centre seam that you can feel through the mattresses and that can cause the connector bracket to bind.
Step 3: Route Power and Sync Cables Along the Inner Edge
[Leva Split Queen Assembly – Step 3]
Keep both bases face-down while you handle the wiring. Locate the power cord port and the sync port on each unit. Thread each power cord through the cable management channel that runs along the inside long edge of the frame, which is the edge that will face the centre of the bed.
Connect the sync cable between the two bases at the designated sync ports. This cable lets both motors respond to shared commands like zero-gravity or anti-snore from either remote or the app. Leave both power cords unplugged from the wall for now.
Common Mistake: Routing power cords along the outer edge of the frame leaves them exposed after the bases are pushed together, which creates a trip hazard and a possible pinch point. Always use the inner channel.
Step 4: Flip and Join the Two Bases
[Leva Split Queen Assembly – Step 4]
Work with a second person for this step. Flip each base upright one at a time by rotating it toward the head end of the frame. Position the two bases side by side with the sync-cable ports facing each other at the centre.
Slide the bases together until the inner rails sit flush. If your package includes a centre connector bracket, align the bracket holes with the frame slots and hand-tighten the included bolts. The combined footprint should now match a standard queen bed at about 153 cm wide.
Common Mistake: Skipping the centre connector bracket allows the two bases to drift apart during the night, which creates a gap that you can feel through the mattresses.
Step 5: Install Mattress Retainers at the Foot End
[Leva Split Queen Assembly – Step 5]
Mattress retainers clip onto the foot end of each base and keep the mattresses from sliding when the head or foot section rises. Clip one retainer to the outer foot corner of each base for a total of two retainers.
Leave the centre seam clear. The mattresses press against each other there and do not need extra hardware to stay in place.
Common Mistake: Installing retainers at the head end instead of the foot end restricts mattress flex during elevation and can pull on the mattress cover.
Step 6: Pair the Remotes and Connect the Leva App
[Leva Split Queen Assembly – Step 6]
Plug both power cords into separate 120 V grounded outlets. Each base needs its own outlet, because sharing a single outlet with a power bar can overload the circuit and trip a breaker when both motors run together.
Once powered, each remote enters pairing mode automatically. Hold the remote close to its base and press the pairing button until the indicator light confirms connection. Download the Leva Sleep app, sign in or create an account, and follow the prompts to add each base as its own device.
The app lets you link both sides under one household profile so shared commands such as anti-snore or zero-gravity move both bases at the same time.
Common Mistake: Pairing both remotes to the same base leaves one side without control. Confirm each remote moves only its own base before you continue.

Step 7: Place and Secure Your Mattresses
[Leva Split Queen Assembly – Step 7]
Use the remotes to lower both bases to the flat position before you place the mattresses. Slide each twin-XL mattress onto its matching base from the foot end and align the mattress edge with the outer rail.
The two mattresses should meet at the centre seam without a gap. Leva’s purpose-designed fitted sheets use deep pockets and reinforced elastic to bridge the centre seam and keep both mattresses contained during elevation.
Common Mistake: Placing a standard queen mattress across both bases instead of two twin-XL mattresses removes independent elevation and cancels the split-queen benefit.
Step 8: Test Motion and Fine-Tune the Setup
[Leva Split Queen Assembly – Step 8]
Run each base through its full range of motion. Raise the head to maximum, then the foot to maximum, and return to flat. Listen for grinding or clicking from the motor. A brief hum at the start of movement is normal as the motor engages.
Use the app to test the zero-gravity preset on both sides at the same time. Adjust leg height if the bed surface does not line up with your headboard. Confirm the sync cable is fully seated by sending a shared command from one remote and checking that both bases respond.
Common Mistake: Skipping the full-range test can hide a binding cable or loose leg until after the mattresses are loaded and the bed is in nightly use.

Before you sleep on your new split queen, confirm every item on this checklist:
- Both bases are level and the sleeping surface feels flush across the centre seam
- Each remote controls only its own base
- A shared command from the Leva app moves both bases at the same time
- Power cords run through the inner cable channel and are not pinched
- Mattress retainers are clipped at the foot end of each base
- Both mattresses sit firmly against the retainers with no gap at the centre seam
- The full elevation range runs smoothly and quietly on both sides
Advanced Tips to Keep Your Bed Performing Well
Once the bed works smoothly, a few extra habits help maintain performance over time.
Firmware updates: The Leva app sends a notice when a firmware update is available for either base. Apply updates with both bases flat and plugged in. Updates usually complete quickly and can improve motor calibration and app responsiveness.
Seasonal adjustments: Canadian homes see large humidity swings between summer and winter. Wood-framed bed surrounds can expand or contract and may nudge the bases slightly. Check the centre connector bracket bolts at the start of each heating season and re-snug them if needed.
Accessories: Leva’s purpose-designed bedding, including fitted sheets with reinforced elastic, duvet clips, and mattress protectors, is built to flex with the base through its full range of motion. Standard bedding often pulls free at elevated positions above 30 degrees.
Frequently Asked Questions
Can a split queen adjustable bed use a standard queen headboard?
Yes. The two twin-XL bases together match the width of a standard queen at about 153 cm, so most queen headboards attach without modification. Confirm your headboard’s bracket spacing before ordering, because most North American queen headboards measure approximately 62–66 inches wide.
Do both sides of a split queen move together or independently?
Each side can move on its own or in sync with the other. Every base has its own motor, remote, and power supply, so each partner can raise or lower their side independently at any time. The Leva app also offers shared presets such as zero-gravity or anti-snore that move both bases together with a single command, which is a key advantage over a standard adjustable queen.
Is white-glove assembly available everywhere in Canada?
Leva Sleep’s white-glove delivery and setup service is currently available in Ontario and Alberta. The service includes delivery to the bedroom, full assembly, leg-height adjustment, a product walkthrough, and removal of your old bed. Customers in other provinces can still purchase and self-assemble by following the steps in this guide.
What if one base stops working after assembly?
Each base operates independently, so a fault on one side does not affect the other. The working base continues to function normally. Contact Leva Sleep support with your order number, because the team can diagnose many issues remotely through the app’s diagnostic mode. If a motor or control unit needs replacement, Leva’s in-house service team manages warranty repairs directly without third-party service centres.
Will any twin-XL mattress work on a Leva split queen base?
Most all-foam and hybrid pocket-coil twin-XL mattresses work well with adjustable bases. Innerspring mattresses with a continuous coil system are not recommended, because the coil grid resists bending and can be damaged by repeated elevation. Leva designs its own all-foam and hybrid mattresses to flex through the full articulation range of its bases and also partners with brands such as Tempur-Pedic, Simmons, Beautyrest, Serta, and Kingsdown. If you choose a third-party mattress, confirm with the manufacturer that it is rated for adjustable base use before you order.
Conclusion: From Carton to First Sleep
Assembling a split queen adjustable bed stays manageable when you treat it as two synchronized twin-XL units instead of one complex queen system. The steps above guide you from unpacking and leg attachment through wiring, joining the bases, installing retainers, pairing controls, placing mattresses, and running a full test.
For couples in Ontario or Alberta who prefer trained professionals to handle everything, Leva Sleep’s white-glove service offers a direct path from delivery to a fully assembled, ready-to-use bed. Configure your split queen package with or without white-glove setup directly from the collections page.
