Base Won't Go Flat (All Models)
If the head or foot section of your bed will lift but will not return to the horizontal flat position.
- Make sure the base is level, and you are not using the graphic representation of the base that shows on the remote as your reference.
- Verify that it's not the mattress curling up creating the appearance the bed is not flat.
- Check for obstructions like pillows, blankets, or anything preventing the deck from lowering.
- Verify the head of the bed is at least 2 inches away from the wall.
- If you have a Split King size bed, make sure the bases are not too close together. This may be causing the bed to not to go completely flat.

- If unresolved, note the 4-digit error code and continue to FlexFit Adjustable Base Error Code.
- If it wakes up on the home screen, continue to Troubleshooting E3 Connectivity Error.
Noisy Base (All Models)
Usually, sound is related to the acoustics of the room the bed is in. You can expect a humming sound from the lift motors when the bed is adjusting and a low drumming noise from the massage motors when the massage feature is turned on.
To minimize the level of normal sound emitted by your FlexFit Adjustable Base, we recommend the following:
- If you are hearing a rattling sound, check if there are headboard brackets that were left in their packaging under your bed.
- If your bed is on hard wood or tile, put carpet squares or rubber caster cups under the legs of the base
- Raise the head or foot slightly to alleviate contact with the frame when using the massage feature.
- Make sure there isn’t anything under the bed that may be vibrating against the base.
- Please contact us if you are hearing grinding or abnormal noise while operating your bed.
Massage doesn't work
FlexFit+
- Ensure power down box, the black power box underneath the base, is plugged into a working outlet, and receiving power.
- Make sure the remote has working batteries and is operating other functions of the base.
FlexFit 3
- Check under your bed to see if a wire or cable has been disconnected or damaged. We recommend pushing in all FlexFit control system connections to ensure they are secure.
Lighting doesn't work
FlexFit 3 Nightstand Lamp
There are between two to four outlets on the FlexFit 3 control box. Two are controllable nightstand outlets and two standard outlets.
FlexFit control box

- Press the Lights button on your remote.
- Select the light you want on or off and press Enter.
A light bulb icon will appear when the light selected is on and will disappear when the light is turned off.

- Verify FlexFit control box is getting power by verifying the red power switch is illuminated and testing that you can adjust the base.
- If you are still unable to turn on the nightstand through the remote, test the lamp by plugging it into a wall outlet.
- Check to see if the light bulb needs to be replaced.
FlexFit 3 Underbed lighting
- Verify the FlexFit control box is securely plugged in, and the red switch is illuminated indicating the system is receiving power.
- Verify the red underbed lighting cable is securely connected to the FlexFit control box and the red wire extension under the bed.
