- Disconnect hoses at the air chambers (coming out of the mattress) then cap the air chambers to help keep air inside.
- Locate the control system based on your base type.
- Disconnect the hoses, connectors, and power cord from the old control system.
- Install the new control system, reconnect the hoses and wires, then plug the bed back in.

Before you Replace the Control System
Before you begin, gather the items below and make sure you have enough space to safely access the control system (pump) area.

Note: If you have an integrated base with a compartment, it may be easier to disconnect and remove the mattress before replacing the control system.
Step 1: Prepare your bed
- Ensure your bed is in the flat position (adjustable bases only).

- If you have an integrated base: Stand at the foot of your bed and move the mattress to the left so it slightly hangs off the edge of the base. Lift the compartment lid to access the control system.
- If you do not have a base, purchased your bed before 2017, or a ComfortMode™ Mattress: The control system is usually placed on the floor at the head of the bed.
- If you have a FlexFit® adjustable base: The control system is located on the sleeper-left side at the foot of the bed, underneath the base.
-
FlexFit® adjustable bases only: Disconnect the mattress from the base at the foot of the bed. Lift the decking panels to access the control system. One person should hold the mattress while the other disconnects the old control system and installs the new one.
- Magnet Attach – Lift the mattress at the foot of the bed. Use your thumbs to push up on the edge of each magnet and disconnect it from the base.
- Strap Attach – Lift the mattress at the foot of the bed. Find the gray straps, lift the loose end to unsnap the straps.

- Place the new control system near where the old one was located.
- Reconnect each hose by gently pushing until you hear or feel the connector click into place.
- Reconnect the remaining wire connectors by gently pushing each plug into the matching port.
- Place the control system back into the compartment, bin or shelf or place it near the head of the bed.
- Plug the bed back in.
- Mattresses purchased before 2017: Place all foam parts back inside your mattress. Zip the top panel to the bottom section of your mattress cover to close your bed.
