The Flex LS is our streamlined adjustable base. Head up, foot up, flat, with a full massage system layered on top. It does not have the neck and lumbar zones of the higher-tier models, but it covers everything most people actually reach for every night.
This guide translates the Flex LS owner's manual into one readable resource. Whether you are setting it up for the first time or working through a problem months later, everything you need is here.

Before You Start
Dispose of all packing materials immediately. Plastic bags pose a smothering risk to children and pets. Keep children and pets clear of the area before operating any moving parts.
How to Set Up the Flex LS
The Flex LS sets up two ways: freestanding on its own legs, or inside a bed frame on a slat base. Pick your method before you start, because the steps split early.
Setup Without a Bed Frame
Seven steps from box to first test. Work through them in order; the leg installation sequence matters more than it looks.
Freestanding Setup, Step by Step
-
1Open and unpack Open the box and remove all accessories. Set them aside and verify every part is present before discarding the packaging.
-
2Remove the safety clip Pull the red plastic safety clip from the folded base. Remove the locking pin by pulling upward and rotating 90 degrees counterclockwise to release the fold.
-
3Install the first four legs Using a flipping motion, stand the base upright on the headboard end. Install four legs there and tighten each one fully before moving on.
-
4Flip and install the remaining legs Flip the foot section out of the box and lay the base flat. Install the final two legs at the foot end, then tighten all six completely.
-
5Attach the mattress retainer bar For our mattresses, insert the flat retainer bar into the securing strap at the bottom of the mattress, then snap it into the retainer mounts. For other mattresses, install the bar one side at a time using the standard method.
-
6Make the base flat and connect power Lay the base completely flat. Connect the DC power cord from the control box into the power supply, then plug the AC cord into a grounded outlet. A surge protector is strongly recommended.
-
7Insert batteries and test Insert AAA batteries into the remote. Test all functions before placing your mattress on the base.
Setup Inside a Bed Frame
Skip the legs entirely. Place the Flex LS directly onto the slat surface and flip it flat, then route the DC power cord through the bottom or side of the frame toward your power source.
From there, the retainer bar installation and power connection follow the same steps as the freestanding setup. Everything downstream of the legs is identical.
Remote Control: Every Button Explained
The Flex LS remote handles head and foot adjustment independently, plus massage, LED lighting, and two programmable positions. There is no LCD screen on this remote; confirmation comes through blue backlight flashes and audio tones.
Head Up and Down
Raises and lowers the head section independently. Useful for reading, watching TV, or finding the angle that feels right.
Foot Up and Down
Raises and lowers the foot section independently, including positions that bring your legs above the level of your heart.
Flat
Returns the base to fully flat in one touch. Always store the base flat when it is not in use.
Programmable Positions
Save two custom positions. Hold the LED button, then hold your chosen position button for 5 seconds until you hear a beep. Repeat the steps to update.
Head and Foot Massage
Three intensity levels per zone. Press the head or foot massage button to cycle through intensities; press STOP to turn both zones off.
Under-Bed LED
Toggles under-bed lighting on and off. The LED button also does double duty as part of the programmable position save sequence.
That double duty on the LED button trips people up more than anything else on this remote. If a saved position is not sticking, the button order is almost always why.
Syncing Two Flex LS Bases
Running two Flex LS bases in a split king or similar setup? You can sync them to move together. Which method you use depends on your remote version, so check that first.
Wireless Sync
- Confirm both remotes are individually paired to their foundations.
- Bring both bases to the flat position.
- Press and hold HEAD and the up button on both remotes at the same time for 5 seconds, until the blue backlights flash.
- To unsync, hold HEAD on both remotes at the same time for 5 seconds until the backlights flash again.
Wired Sync
- Unplug both foundations from power.
- Connect the male ends of the sync cord to the female sync plugs on both control boxes.
- Plug both foundations back into power.
- Confirm all cords are secure. Either remote now operates both foundations at once.
Not sure which remote version you have? Check the label on the back of the remote for the model number; V2.0 or newer is printed there if it applies. If nothing is printed, assume pre-V2.0 and use the cord.
Need to Re-Pair the Remote?
Unplug the power cord and remove any 9V backup batteries from the power supply. Press and hold the HEAD button and the down button at the same time until the blue backlights turn off, then plug the cord back in. You will hear an activation sound within 2 seconds confirming the pairing is complete.
Setting Up the BEDGEAR App
The app gives you full phone control over the Flex LS. It connects over Bluetooth and pairs automatically when you open it, with no account and no extra steps.
How to Download and Connect
Search for "bedgear" in the App Store or Google Play and install the app. Turn on Bluetooth and confirm the Flex LS is powered on before opening it. The app finds the base automatically within the 33-foot (10-meter) Bluetooth range.
From there you get head and foot adjustment, programmable positions, massage intensity, and under-bed lighting. The settings screen also lets you rename the base, check the control box serial number, and open the built-in troubleshooting guide.
Pacemaker Notice
The Flex LS contains Neodymium magnets that may interfere with pacemakers, ICDs, and other magnetically sensitive medical devices. If you use such a device, consult your physician before using this product. The massage feature vibrations may also be falsely interpreted as movement by some pacemakers. Speak with your doctor before using the massage function.
Troubleshooting the Flex LS
Most issues come down to power, pairing, or sync. Work through the table below before reaching for the phone.
Common Issues and Fixes
| Problem | What to Check |
|---|---|
| Remote won't respond | Replace the AAA batteries first. If the batteries are fine, re-pair the remote using the steps above. |
| Base won't power on | Confirm the DC cord is fully connected to both the control box and the power supply. Check that the AC cord is plugged into a working grounded outlet. A surge protector is strongly recommended. |
| Sync not working between two bases | For wireless sync, check the remote version (V2.0 or newer required) and make sure both bases are fully flat before you start. For wired sync, confirm the cord is fully seated in both control boxes and both bases are powered. |
| Programmable position not saving | Hold the LED button first, then hold the programmable position button; the order matters. Hold both for the full 5 seconds until you hear the beep, because releasing early will not save the position. |
| Audio system won't pair or has no sound | Restart the base. Confirm you are within 26 feet and not pairing through a wall. Volume at minimum on the paired device will also produce no sound. Only one device pairs at a time, so disconnect the current one before adding another. |
If your issue is not covered above, open the BEDGEAR app and check the troubleshooting section in settings. You can also reach our customer service team at 631-414-7763.
Getting the Most From Your BEDGEAR Flex LS Adjustable Base
Setup rewards patience. Install the legs in order, tighten all six before moving on, and test every remote function before the mattress goes on. Ten minutes there beats lifting a mattress back off later.
After that, two things make the Flex LS feel like yours: save both programmable positions, and confirm your remote version before you try to sync a second base. If you want the neck and lumbar zones this model leaves out, our Flex LSX setup guide covers the step up in the same detail.
