5. Operating Instructions
Your FLEXISPOT XL51 recliner comes with two remote controls: one for lift and recline functions, and another for massage and heat.

- Recline: Press and hold the "Down" arrow button (usually the bottom button) to recline the backrest and raise the footrest. Continue holding to reach a nearly 180° lay-flat position.
- Adjust Backrest Independently: Use the dedicated backrest adjustment buttons (often depicted as a chair with only the back moving) to adjust the backrest angle without moving the footrest.
- Adjust Footrest Independently: Use the dedicated footrest adjustment buttons (often depicted as a chair with only the footrest moving) to adjust the footrest height without moving the backrest.
