A FlexFit Adjustable Base will fit inside most standard sized furniture. The FlexFit Base must stand directly on the floor inside your furniture and requires an underbed clearance of 5 inches for any cross-beams or slats. If your bed frame requires slats we recommend measuring the distance from the floor to the top of the slats. If the measurement is less than 5 inches the standard sized legs included with the base will work with your furniture. For a clearance of greater than 5 inches we recommend adding taller legs to your order before your delivery. Please call us or chat with us online if you need assistance ordering optional accessories for your bed.

FlexFit™ headboard brackets are sold separately. For instructions to attach your FlexFit Headboard brackets please refer to the FlexFit™ Assembly Guide.

Our customizable Presets are only a starting point. You can save over any Preset to further individualize your comfort and easily return to the default setting at any time.

To begin customizing your Presets, select a side of the bed. Raise the head and foot to your Favorite setting. To save as your Favorite, hold down the Star/Favorite button until prompted to save the setting. Save as your Favorite, or select an existing Preset to save over the factory setting.

To reset your Presets to the factory default settings press the Menu Button. Use the Up or Down Arrow to Select System; press Enter. Select Setting, Press Enter sfter selecting settings option. Select Bed Positions. Select All Positions or the Position you would like to reset to the factory default settings.

To turn the massage on, press the Wave/Massage button. Select upper, lower or full body and press Enter. Choose different intensities to create an individualized massage.

You can use your remote to control the under-bed light and your bedside table lamps.

To control your nightstand lamps with your remote, plug them into the left and right nightstand outlets on your FlexFit 3 Control System and switch the lamps to the on position. Press the light button to turn the lamps on or off.

To adjust the brightness of the under-bed lighting, press the Menu button. Use the Up or Down Arrow to select System; press Enter. Select Settings; press Enter. Select Reset Preferences; press Enter. Select Nightlight to adjust the brightness between high, medium or low.

You can adjust your FlexFit adjustable base to help take pressure off your pain points. Start by adjusting the bed to the Zero Gravity setting, which allows your body to float into a weightless position that alleviates pressure at the head, shoulders, hips, and knees. From Zero Gravity, make minor adjustments to the head and foot position until you find the comfort level that is best for you. To easily return to it, hold down the Star/Favorite Button, or save over an existing default setting to make it your own.

Clean liquid spills with a dry, clean, absorbent white cloth. Blot liquid spills gently, avoid rubbing the spills. Rinse with clean water and blot dry with clean white absorbent cloth. For stubborn spills, use a mild detergent and warm water solution to spot clean. Remove soap residue from the surface with clean water. If a stain remains, a solvent such as odorless mineral spirits, may be used.

We recommend working with two people to disassemble or reassemble your bed.

In most cases, the sound emitted from your Adjustable Base 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 Customer Service if you are hearing grinding or abnormal noise while operating your bed.

In most cases, either the base has lost connection to power, or there is an obstruction at the head or foot of the bed that is preventing the base from adjusting normally. Check to make sure the adjustable base is plugged in and that the base is not obstructed. 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 fully lower.

For older model adjustable bases (sold 2013 and before), follow these steps to manually return your base to flat. Press and hold the learn button on the power down box to slowly force the bed to go flat. If this function does not work, replace the battery in the Power Down Box. The Power Box requires a 9-volt battery.

If Bed Position is not listed as an option on your Home Menu, it means there was an issue with the setup of the remote.

Before you going through guided setup steps, ensure that all components of your bed are securely connected to power. The FlexFit Control System should be plugged directly into a wall outlet, not a surge protector. A power strip with a minimum of 10 amps is acceptable if additional outlet space is needed.

This usually occurs when a connection is loose. Check under your bed to see if a wire or cable has been disconnected or damaged. We recommend pushing in all FlexFit Connections to ensure that they are secure.

Check the mounted connections underneath the base. If you have an Eastern King, FlexTop King or Split King, please check the mounted connections under both sides.

Check the Connections on the back of the FlexFit Control System. Push in connections to ensure that they are secure.

After verifying connections, unplug the FlexFit Control System for 20 seconds then plug back in. If this does not resolve the issue you are experiencing, please contact Customer Service for further assistance.
